Summary New surgical approaches are being developed to solve old problems and often require surgeons to revisit familiar ana to my from an unfamiliar perspective or with a different understanding of complex ana to mic relationships. Examples of innovative surgical approaches that require renewed understanding of ana to mic relationships include laparoscopic or robotic surgery, midurethral incontinence slings that traverse the obtura to r or retropubic spaces, and prolapse kits that traverse pararectal and paravesical spaces. Ana to mic alterations secondary to disease, congenital variation, or intraoperative complications may make familiar surgical terri to ry suddenly seem foreign. All of these situations require surgeons to be perpetual students of ana to my, regardless of their breadth or depth of experience. Several strategies for continuing education in ana to my are suggested: Review relevant ana to my before each surgical procedure. Operate with more experienced pelvic surgeons, particularly when incorporating new surgical procedures in to practice. Periodically dissect fresh or fixed cadaveric specimens; this practice may be arranged through local or regional ana to my boards or medical schools or by special arrangement at the time of au to psy. Take advantage of newer computer-generated three-dimensional pelvic models and virtual reality interactive ana to mic and surgical simula to rs, when available, to better understand functional ana to my and to help plan complicated surgical procedures (49,50).

Berek the regulation and maintenance of normal tissue requires a balance between cell proliferation and programmed cell death, or apop to sis. The regulation of ovarian function occurs through au to crine, paracrine, and endocrine mechanisms. Disruption of these au to crine and paracrine intraovarian pathways may be the basis of polycystic ovarian disease, disorders of ovulation, and ovarian neoplastic disease. Growth fac to rs trigger intracellular biochemical signals by binding to cell membrane recep to rs. Many of the proteins that participate in the intracellular signal transduction system are encoded by pro to -oncogenes that are divided in to subgroups based on their cellular location or enzymatic function. Oncogenes comprise a family of genes that result from gain of function mutations of their normal counterparts, pro to -oncogenes. The normal function of pro to -oncogenes is to stimulate proliferation in a controlled context. Activation of oncogenes can lead to stimulation of cell proliferation and development of a malignant phenotype. Tumor suppressor genes are involved in the development of most cancers and are usually inactivated in a two-step process in which both copies of the tumor suppressor gene are mutated or inactivated by epigenetic mechanisms like methylation. T lymphocytes have a central role in the generation of immune responses by acting as helper cells in both humoral and cellular immune responses and by acting as effec to r cells in cellular responses. T cells can be distinguished from other types of lymphocytes by their cell surface phenotype, based on the pattern of expression of various molecules, as well as by differences in their biologic functions. H Advances in molecular biology and genetics have improved our understanding of basic biologic concepts and disease development. Normal cells are characterized by discrete metabolic, biochemical, and physiologic mechanisms. Specific cell types differ with respect to their mainly genetically determined responses to external influences (Fig. An external stimulus is converted to an intracellular signal, for example, via a cell membrane recep to r. The intracellular signal is transferred to the nucleus and generates certain genetic responses that lead to changes in cellular function, differentiation, and proliferation. Although specific cell types and tissues exhibit unique functions and responses, many basic aspects of cell biology and genetics are common to all eukaryotic cells. Proteins are constantly degraded and replaced depending on the specific cellular requirements. The cell cycle is regulated by a small number of heterodimeric protein kinases that consist of a regula to ry subunit (cyclin) and a catalytic subunit (cyclin-dependent kinase). Association of a cyclin with a cyclin-dependent kinase (CdkC) determines which proteins will be phosphorylated at a specific point during the cell cycle. The duration of the cell cycle may be highly variable, although most human cells complete the cell cycle within approximately 24 hours. During a typical cell cycle, mi to sis lasts about 30 to 60 minutes, the G phase 7 to 10 hours, S1 phase 10 hours, and G phase 5 hours. With respect to the cell cycle, there are three2 subpopulations of cells: Figure 6. Red blood cells, striated muscle cells, uterine smooth muscle cells, and nerve cells are terminally differentiated. Other cells, such as fibroblasts, exit from the G phase in to the1 G phase and are considered to be out of the cell cycle. These cells enter the cell cycle0 following exposure to specific stimuli, such as growth fac to rs and steroid hormones. G Phase1 In response to specific external stimuli, cells enter the cell cycle by moving from the G phase in to the G phase. Release of1 1 the S phase CdkC complex subsequently stimulates entry in to the S phase. Variations in the duration of the G phase of the cell cycle, ranging from less than 8 hours to 1 longer than 100 hours, account for the different generation times exhibited by different types of cells. This inhibition ascertains that each chromosome is replicated only once during the S phase. Failure to detect and correct these genetic errors can result in a broad spectrum of adverse consequences for the organism and the individual cell (1). Exceptions to the diploid cellular content include hepa to cytes (4n) and the functional syncytium of the placenta. Mi to tic CdkC complexes induce chromosome condensation during the prophase, assembly of the mi to tic spindle apparatus, and alignment of the chromosomes during the metaphase. The nuclear envelope breaks down in to multiple small vesicles early in mi to sis and reforms around the segregated chromosomes as they decondense during telophase. Cy to kinesis is the process of division of the cy to plasm that segregates the endoplasmic reticulum and the Golgi apparatus during mi to sis. After completion of mi to sis, cells enter the G phase1 and either re-enter the cell cycle or remain in G. In a complete hydatidiform mole, an oocyte without any nuclear genetic material. This karyotype seems to be found in patients with recurrent hydatiform moles and is associated with a higher risk of persistent trophoblastic disease. These observations demonstrate the importance of maternal genetic material, in particular the X chromosome, in normal embryonic and placental development. Abnormalities of chromosome number, which often are caused by nondisjunction during meiosis, result in well-characterized clinical syndromes such as trisomy 21 (Down syndrome), trisomy 18, and trisomy 13. Genetic Control of the Cell Cycle Cellular proliferation must occur to balance normal cell loss and maintain tissue and organ integrity. This process requires the coordinated expression of many genes at discrete times during the cell cycle (3). In the absence of growth fac to rs, cultured mammalian cells are arrested in the G phase. With the addition of growth0 fac to rs, these quiescent cells pass through the so-called restriction point 14 to 16 hours later and enter the S phase 6 to 8 hours thereafter. The restriction point or G /S1 boundary marks the point at which a cell commits to proliferation. To successfully complete the cell cycle, a number of cell division cycle (cdc) genes are activated. Cell Division Cycle Genes Among the fac to rs that regulate the cell cycle checkpoints, proteins encoded by the cdc2 family of genes and the cyclin proteins appear to play particularly important roles (8,9). The early and delayed-response genes act as nuclear transcription fac to rs and stimulate the expression of a cascade of other genes. Early response genes such as c-Jun and c-Fos enhance the transcription of delayed-response genes such as E2Fs. E2F transcription fac to rs are required for the expression of various cell cycle genes and are functionally regulated by the retinoblas to ma (Rb) protein. Binding of Rb to E2F converts E2F from a transcriptional activa to r to a repressor of transcription. Phosphorylation of Rb inhibits its repressing function and permits E2F mediated activation of genes required for entry in to the S phase. Cdk4-cyclin D, Cdk6 cyclin D, and Cdk2-cyclin E complexes cause phosphorylation of Rb, which remains phosphorylated throughout the S, G, and M phases of the cell cycle. After completion of2 mi to sis, a decline of the level of Cdk-cyclins leads to dephosphorylation of Rb by phosphatases and, consequently, an inhibition of E2F in the early G phase. The Cdk4 inhibi to r P1446A-05, for example, specifically inhibits Cdk4-mediated G -S phase1 transition, arresting cell cycling and inhibiting cancer cell growth (10). Mi to sis is initiated by activation of the cdc gene at the G -M checkpoint2 (11,12). In the presence of abnormally replicated chromosomes, progression past the G -M checkpoint does not occur. Cells exposed to radiation therapy exhibit an S-phase arrest that is accompanied by increased expression of p53. In the presence of p53 mutations, the S-phase arrest that normally follows radiation therapy does not occur (13,14). Apop to sis the regulation and maintenance of normal tissue requires a balance between cell proliferation and programmed cell death, or apop to sis. The reduction in the number of endometrial cells following alterations in steroid hormone levels during the menstrual cycle is, in part, a consequence of programmed cell death (20,21). Programmed cell death, or apop to sis, is an energy-dependent, active process that is initiated by the expression of specific genes. This process is distinct from cell necrosis, although both mechanisms result in a reduction in to tal cell number. Programmed cell death is triggered by a variety of fac to rs, including intracellular signals and exogenous stimuli such as radiation exposure, chemotherapy, and hormones. Cells undergoing programmed cell death may be identified on the basis of his to logic, biochemical, and molecular biologic changes. His to logically, apop to tic cells exhibit cellular condensation and fragmentation of the nucleus. Biochemical correlates of impending programmed cell death include an increase in transglutaminase expression and fluxes in intracellular calcium concentration (23). His to rically, neoplastic growth was characterized by uncontrolled cellular proliferation that resulted in a progressive increase in tumor burden. It is recognized that the increase in tumor burden associated with progressive disease reflects an imbalance between cell proliferation and cell death. Cancer cells fail to respond to the normal signals to s to p proliferating, and they may fail to recognize the physiologic signals that trigger programmed cell death. Modulation of Cell Growth and Function the normal cell exhibits an orchestrated response to the changing extracellular environment.

Patients with a deletion of the long arm of the X chromosome (Xqfi) from Xq13 to Xq26 have sexual infantilism herbals that lower cholesterol purchase ayurslim american express, normal stature, no somatic abnormalities, and streak gonads (7). Patients with a deletion of the short arm of the X chromosome (Xp) usually are phenotypically similar to individuals with Turner syndrome (8). Many genes on the Xp chromosome escape X inactivation and act similarly to genes on au to somes. The effective monosomy created by the deletion results in the phenotypic features of Turner syndrome (5). Most patients with a ring X have ovarian failure and phenotypes similar to Turner syndrome, although some are able to reproduce successfully. These patients differ from those with Turner syndrome in that they are more likely to have intellectual disability and have syndactyly. Half of the women with balanced translocations of the X chromosome to an au to some have gonadal failure. Typically, the normal X is inactivated to preserve the balance of au to somal genes. The gonadal failure can be caused by the chromosomal break occurring in a gene that is required for ovarian function, abnormal meiosis, or X inactivation of the translocated X and adjacent au to somal genes (5,9). The gonads are usually streaks, but there may be some development of secondary sexual characteristics, and a few episodes of uterine bleeding. If Y sequences are present, gonadec to my is advised because of the risk of gonadoblas to ma (22). Rare Enzyme Deficiencies Congenital Lipoid Adrenal Hyperplasia Patients with this au to somal recessive disorder are unable to convert cholesterol to pregnenolone, which is the first step in steroid hormone biosynthesis. A defect was not found in the P450scc gene, which is the conversion enzyme responsible for this step in the pathway. This protein appears to be the rate-limiting step for steroid hormone biosynthesis stimulated by tropic hormones. Genetic clusters of the disorder are found in the Japanese, Korean, and Palestinian Arab populations. With appropriate mineralocorticoid and glucocorticoid replacement, these patients can survive in to adulthood. More than 20 mutations that alter the reading frame of the gene are identified, even though very few people have the disorder (26). Patients with 17fi-hydroxylase deficiency have primordial follicles, but gonadotropin levels are elevated because the enzyme deficiency prevents synthesis of sex steroids. Aromatase Deficiency this very rare au to somal recessive abnormality prevents the affected individual from aromatizing androgens to estrogen (28). This syndrome may be suspected even before birth because most mothers of affected children become virilized during pregnancy. This occurs because the placenta cannot convert the fetal androgens to estrogen and they diffuse in to the maternal circulation. At birth, a female child has cli to romegaly and posterior labioscrotal fusion (ambiguous genitalia). At puberty, there is no breast development, primary amenorrhea, worsening virilization, absent growth spurt, delayed bone age, and multicystic ovaries. Estrogen therapy improves the ovarian and skeletal abnormalities but must be titrated to mimic normal estrogen levels. Estrogen administration should be minimal during childhood and increased at puberty (29,30). Galac to semia In girls, galac to semia often is associated with ovarian failure, but this condition usually is detected by newborn screening programs. A galac to se-1 phosphate uridyl transferase level can be measured to assess the patient for galac to semia or carrier status. Other Causes of Primary Ovarian Failure without Secondary Sexual Characteristics Severe damage to the ovaries before the onset of puberty can lead to ovarian insufficiency and failure to develop secondary sexual characteristics. Ovarian dysfunction can occur in association with irradiation of the ovaries, chemotherapy with alkylating agents. Other causes of premature ovarian failure (also known as primary ovarian insufficiency) are more commonly associated with amenorrhea after the development of secondary sexual characteristics, as described below. Physiologic Delay Physiologic or constitutional delay of puberty is the most common manifestation of hypogonadotropic hypogonadism. Kallmann syndrome is often associated with anosmia (inability to perceive odors), although a woman may not be aware of her impaired sense of smell. The hypogonadism and anosmia arise because of failure of proper neuronal migration during fetal development. Prolactin-secreting pituitary adenomas are rare in childhood and more commonly occur after development of secondary sexual characteristics. Genetic Disorders 5fi-Reductase Deficiency 5fi-Reductase deficiency should be considered a cause of amenorrhea (39). Patients with 5fi-reductase deficiency differ from patients with androgen insensitivity because they do not develop breasts at puberty (Fig. These patients have low gonadotropin levels as a result of tes to sterone levels that are sufficient to suppress breast development and allow normal feedback mechanisms to remain intact. Normal male differentiation of the urogenital sinus and external genitalia do not occur because dihydrotes to sterone is required for this development. Normal internal male genitalia derived from the wolffian ducts are present because this development requires only tes to sterone. Male pattern hair growth, muscle mass, and voice deepening are tes to sterone dependent. Most affected patients are compound heterozygotes, but homozygous au to somal recessive mutations are identified. Pregnancy was achieved in one patient after induction of ovulation with injectable gonadotropins (43). Constitutional delay without underlying causes is less common in girls than in boys, and the reason for lack of development should be vigorously pursued (51). Evaluation of Women with Amenorrhea Associated with the Absence of Secondary Sexual Characteristics A careful his to ry and physical examination are necessary to appropriately diagnose and treat primary amenorrhea associated with hypogonadism. The physical examination may be particularly helpful in patients with Turner syndrome. A his to ry of short stature but consistent growth rate, a family his to ry of delayed puberty, and normal physical findings (including assessment of smell, optic discs, and visual fields) may suggest physiologic delay. Headaches, visual disturbances, short stature, symp to ms of diabetes insipidus, and weakness of one or more limbs suggest central nervous system lesions (38). Galac to rrhea may be seen with prolactinomas, a condition more commonly associated with secondary amenorrhea in the presence of normal secondary sexual characteristics. Partial deletion of the X chromosome, mosaicism, pure gonadal dysgenesis, and mixed gonadal dysgenesis are diagnosed by obtaining a karyotype. Because of the association with coarctation of the aorta (up to 30%) and thyroid dysfunction, patients with Turner syndrome should undergo echocardiography every 3 to 5 years and thyroid function studies yearly. Patients with Turner syndrome should be evaluated for hearing loss, renal malformations, diabetes, and hypertension. If the karyotype is abnormal and contains the Y chromosome, as in gonadal dysgenesis, the gonads should be removed to prevent tumors (13). This diagnosis should be considered when testing indicates elevated serum progesterone (>3. Suprasellar or intrasellar calcification in an abnormal sella is found in approximately 70% of patients with craniopharyngioma (38). Treatment of Amenorrhea Associated with the Absence of Secondary Sexual Characteristics Individuals with primary amenorrhea associated with all forms of gonadal failure and hypergonadotropic hypogonadism need cyclic estrogen and proges to gen therapy to initiate, mature, and maintain secondary sexual characteristics. Prevention of osteoporosis is an additional benefit of estrogen therapy: Therapy is usually initiated with 0. If the patient is short in stature, higher doses should not be used because premature closure of the epiphyses should be avoided. Most of these patients are of normal height, and higher estrogen doses may be used initially and reduced to the maintenance doses after several months. Estrogen can be given daily in combination with proges to gen (medroxyprogesterone acetate or progesterone) to prevent hyperplasia that could result from unopposed estrogen stimulation of the endometrium in patients with a uterus. Oral micronized progesterone may be administered at a daily dose 100 mg every day of the month or 200 mg daily for 12 to 14 days per month. Cyclic hormone therapy (with 12 to 14 days of proges to gen per month) more closely mimics the natural menstrual cycle. Progesterone supposi to ries may be administered at a dose of 50 mg daily or 100 mg for 12 to 14 days monthly. Occasionally, individuals with mosaicism and gonadal streaks may ovulate and be able to conceive either spontaneously or after the institution of estrogen therapy. If 17fi-hydroxylase deficiency is confirmed, treatment is instituted with corticosteroid replacement and estrogen. If possible, therapeutic measures are aimed at correcting the primary cause of amenorrhea: Craniopharyngiomas may be resected with a transsphenoidal approach or during cranio to my, depending on the size of the tumor. Some studies show improved prognosis with radiation therapy used in combination with limited tumor removal (38,53). Prolactinomas and hyperprolactinemia often may respond to dopamine agonists (bromocriptine or cabergoline) (55). Specific therapies are directed to ward malnutrition, malabsorption, weight loss, anorexia nervosa, exercise amenorrhea, neoplasia, and chronic diseases. This form of therapy is impractical because it requires the use of an indwelling catheter and a portable pump for prolonged periods and the lack of availability of this equipment in the United States. The primary focus of treatment should be to correct the underlying problem that is causing the menstrual dysfunction. If a patient is unable to correct the underlying condition, she may be treated with cyclic estrogen and proges to gen therapy at least until sexual maturity is achieved. Once sexual maturation is achieved, hormone therapy can be continued to treat hypoestrogenic symp to ms until the underlying disorder leading to amenorrhea can be adequately treated. Patients with Kallmann syndrome, and patients with other etiologies for hypothalamic amenorrhea, can be treated with hormone replacement, as described above. For individuals with anorexia, intensive treatment to achieve weight gain and emotional well-being is preferable to long-term treatment with hormone therapy (56). If the patient has physiologic delay of puberty, the only management required is reassurance that the anticipated development will occur eventually. The gonads of these individuals should be removed when the condition is diagnosed to prevent malignant transformation. There is some evidence that hirsute individuals without Y chromosomes should undergo gonad removal. One patient with hirsutism and the karyotype 45,X was noted to have a streak gonad; the contralateral gonad was dysgenic and contained developing follicles, well-differentiated seminiferous tubules, and Leydig cells. Clomiphene citrate is most often ineffective for inducing ovulation in patients with hypogonadism who desire pregnancy because such patients are hypoestrogenic. In patients with hypogonadism, ovulation induction with injectable gonadotropins is generally successful. There are reports of deaths in pregnant patients with Turner syndrome resulting from aortic dissection and rupture (58). Careful counseling and investigation should be undertaken in patients with Turner syndrome before treating them with donated oocytes. Amenorrhea with Secondary Sexual Characteristics and Abnormalities of Pelvic Ana to my Causes Outflow and Mullerian Anomalies Amenorrhea occurs if there is blockage of the outflow tract, if the outflow tract is missing, or if there is no functioning uterus (Table 30. Most women with mullerian abnormalities will have normal ovarian function and thus will have normal secondary sexual characteristic development. Such outflow obstructions include imperforate hymen, transverse vaginal septum, and absence of the cervix or vagina. Transverse blockage of the outflow tract with an intact endometrium frequently causes cyclic pain without menstrual bleeding in adolescents. The blockage of blood flow can cause hema to colpos, hema to metra, or hemoperi to neum, and endometriosis. Mullerian Anomalies Mayer-Rokitansky-Kuster-Hauser syndrome includes vaginal agenesis with variable mullerian duct abnormalities accompanied in some cases by renal, skeletal, and audi to ry abnormalities (60). Mullerian agenesis accounts for approximately 10% of cases of primary amenorrhea (2). Mayer Rokitansky-Kuster-Hauser syndrome is associated with abnormal galac to se metabolism (64). Absence of Functioning Endometrium Amenorrhea may occur if there is no functioning endometrium. When the findings of the physical examination are normal, ana to mic abnormalities of the uterine cavity should be considered. A congenitally absent endometrium is a rare finding in patients with primary amenorrhea. Asherman syndrome, which is more common with secondary amenorrhea or hypomenorrhea, may occur in patients with risk fac to rs for endometrial or cervical scarring (Fig. Such risk fac to rs include a his to ry of uterine or cervical surgery, infections related to use of an intrauterine device, and severe pelvic inflamma to ry disease. Asherman syndrome is found in 39% of patients undergoing hysterosalpingography who previously underwent postpartum curettage (65). Infections such as tuberculosis and schis to somiasis may cause Asherman syndrome but are not common for women who have lived their whole lives in the United States. Cervical stenosis resulting from surgical removal of dysplasia (cone biopsy, loop electroexcision procedure) may lead to amenorrhea.

A variety of graft materials have been employed with posterior colporrhaphy and defect-directed repairs including au to graft top 10 herbs buy ayurslim without prescription, allograft herbals medicine order ayurslim with visa, xenograft herbs not to mix ayurslim 60caps overnight delivery, and synthetic mesh herbs nursery cheap 60 caps ayurslim with mastercard. It can either be intended to replace existing fascia as a permanent barrier or to provide an absorbable scaffold for collagen deposition herbals on york carlisle pa cheap ayurslim 60 caps with amex, scar formation lotus herbals 3 in 1 matte sunscreen discount ayurslim 60caps on line, and remodeling. The ideal material should have a low erosion rate, be relatively inexpensive, and decrease recurrence rates without causing bowel or sexual dysfunction. The outcomes for rec to cele repair using graft materials placed either vaginally or abdominally appear in Table 28. High ana to mic cure rates of 89% to 100% occurred, and symp to ms of constipation, difficult evacuation, and vaginal bulge also appeared to improve. Patients were randomly assigned to fascial replacement with polyglactin 910 mesh at the time of anterior and posterior colporrhaphy. There were no differences in recurrence rates when comparing 70 women with a traditional colpoperineorrhaphy with 73 women having a traditional repair plus mesh: 10% versus 8%, respectively. This study did not describe changes in bowel or sexual function, and there were no mesh-related adverse events. As previously noted, the randomized controlled trial comparing posterior colporrhaphy, defect-directed repair, and defect-directed repair with porcine small intestine submucosal graft augmentation revealed higher ana to mical failure rates in the graft-augmented group compared to the site-specific alone or the posterior colporrhaphy group (46% vs. Importantly, the risks of vaginal mesh erosion and severe complications may be relatively low but carry significant morbidity, including rec to vaginal fistula, persistent vaginal bleeding and discharge, dyspareunia, and the need for additional surgery (199,207). Nonsynthetic grafts appear to be safer, with fewer erosions compared with synthetic grafts; however, there is no evidence to suggest that the addition of a graft to the posterior compartment improves outcomes (210,218,219). Abdominal Rec to cele Repair the abdominal approach to rec to cele repair may be of value when a superior defect in the rec to vaginal fascia occurs in a patient with accompanying enterocele, uterine prolapse, or vault prolapse. If a patient is undergoing an abdominal or laparoscopic procedure such as a sacral colpopexy, the graft can be extended along the posterior vaginal wall to correct proximal defects in the rec to vaginal septum (220). The indication for this procedure, as well as the need for additional vaginal repair of distal defects, is often determined intraoperatively. An ancillary study from the Pelvic Floor Disorders Network evaluating bowel symp to ms 1 year after sacrocolpopexy found that the majority of bothersome bowel symp to ms resolve after this procedure. There was no difference in pos to perative bowel symp to ms among those who underwent a concomitant rec to cele repair and those who did not. It is important to note that the study was not developed to evaluate the impact of concomitant rec to cele repair on bowel symp to m resolution, and those who underwent a rec to cele repair had more severe baseline bowel symp to ms including worse obstructive symp to m (221). Sacral Colpoperineopexy for Perineal Descent Sacral colpoperineopexy is a modification of sacral colpopexy aimed at correction of apical prolapse combined with rec to cele and perineal descent (39). A continuous graft is placed from the anterior longitudinal ligament of the sacrum down to the perineal body. This procedure can be accomplished either through a to tal abdominal approach or a combined abdominal and vaginal procedure. If performing a to tal abdominal approach, the rec to vaginal space is opened, and the rectum is dissected off the posterior vaginal wall and rec to vaginal septum to ward the perineal body. The graft is secured to additional points along the posterior vaginal wall and apex, and sacral colpopexy is completed in the usual fashion. If performing a combined abdominal and vaginal approach, the graft is secured to the perineal body vaginally. The posterior vaginal wall is opened, and a defect-directed rec to cele repair is performed. Sacral colpopexy is accomplished in the usual fashion except that the vaginal dissection is opened superiorly, creating a window to the abdominal dissection. The graft can then be passed down from the abdominal field to the vaginal field and anchored inferiorly to the perineal body and laterally to the arcus tendineus fascia rec to vaginalis (Fig. This sagittal view shows the posterior graft sutured to the rec to vaginal fascia and perineal body after defect-directed rec to cele repair. Complete cessation of defeca to ry dysfunction symp to ms was accomplished in 66% of patients. The failure rate was 25% and mesh erosion rate was 5% for 205 patients with up to 10-year follow-up. A study of Mersilene mesh erosion rates related to sacral colpopexy and sacral colpoperineopexy noted similar erosion rates between sacral colpopexy and colpoperineopexy when the vagina was not opened (3. However, the erosion rate was 16% with vaginal suture placement and 40% when the mesh was placed vaginally. The use of nonsynthetic grafts such as dermal allograft and xenograft may help prevent high erosion rates. In a case series of 11 patients, researchers performed sigmoid resection (if indicated) and suture rec to pexy in conjunction with sacral colpoperineopexy using AlloDerm for women with coexistent rectal prolapse, perineal descent, and defeca to ry dysfunction. A recently published retrospective cohort of 38 women revealed high satisfaction following abdominal sacral colpoperineopexy, despite the persistence of obstructed defecation symp to ms 5 years after surgery (225). Sacral colpoperineopexy may have value for a select group of patients, but larger prospective series with long-term ana to mic and symp to matic outcomes are necessary to evaluate the durability of this procedure. Rectal Prolapse Numerous surgical procedures have been described for the treatment of rectal prolapse and are broadly categorized in to perineal or abdominal approaches. Most surgeons prefer an abdominal procedure because of lower recurrence rates, reserving perineal procedures for more debilitated patients. Abdominal Procedures Abdominal procedures vary with respect to the extent of rectal mobilization, method of rectal fixation, and inclusion or exclusion of bowel resection. During abdominal rec to pexy, the mesorectal plane is developed and the rectum mobilized down to the pelvic floor posteriorly, with care taken to identify and preserve the hypogastric nerves. The concern is that division of the lateral ligaments will lead to rectal denervation and increased pos to perative constipation. If performing a suture rec to pexy, the fascia propria of the rectum is secured to the sacral periosteum from S-1 to S-3 (226). If performing a sigmoid resection with the rec to pexy (Frykman-Goldberg resection rec to pexy), the bowel resection is performed after mobilization and before suturing (227). The theoretical advantages of a rec to sigmoid resection are creation of a dense area of fibrosis between the anas to motic suture line and the sacrum; removal of abundant rec to sigmoid, avoiding to rsion or volvulus; additional fixation through straightening of the left colon and decreased mobility from the phrenocolic ligament; and relief of constipation in select patients. It is typically reserved for patients with a long redundant sigmoid colon, although specific criteria have not been proposed. Mesh rec to pexies are usually avoided because of concern for increased complications and infections associated with placement of a foreign body at the time of bowel resection. There are two basic types of mesh rec to pexy: posterior mesh rec to pexy and anterior sling rec to pexy (Ripstein procedure) (228,229). A variety of materials have been used for this procedure, including absorbable and permanent mesh. The assumption is that placement of this material will provide increased support through increased fibrous tissue formation. During the Ripstein procedure, an anterior sling of fascia lata or synthetic mesh is placed in front of the rectum and sutured to the sacrum. Modifications using a posterolateral wrap have been developed to resolve this problem. In a series of more than 10 patients, there were five open series and five laparoscopic reports for suture rec to pexy (230). Most reports showed an improvement in fecal incontinence symp to ms, but the results for constipation were variable. There were no mortalities noted and no difference between laparoscopic and open results. For posterior mesh rec to pexy, there were 14 open series and five laparoscopic reports. As with suture rec to pexy, there was general improvement in fecal incontinence, mixed results for constipation, and no differences between laparoscopic and open outcomes. The mortality rate was between 0% and 3%, with increased rates of infection if resection rec to pexy was performed. For anterior sling rec to pexy (Ripstein procedure), there were eight studies with a recurrence rate between 0% and 12%. Again, there was a trend to ward improvement of fecal incontinence and mixed response for constipation. For resection rec to pexy (Frykman-Goldberg procedure), there were nine open series and three laparoscopic reports. There was general improvement in continence as well as an overall reduction in constipation observed in most studies. This study was a small, randomized trial comparing 15 patients undergoing resection rec to pexy to 15 patients undergoing absorbable mesh rec to pexy. The authors concluded that sigmoid resection did not seem to increase operative morbidity but tended to diminish pos to perative constipation, possibly by causing less outlet obstruction. The laparoscopic series demonstrated similar safety and efficacy to the open techniques, and the effect on continence and constipation tended to mirror the type of rec to pexy performed. In a small, randomized trial, there were significant short-term benefits with laparoscopic rec to pexy compared with open rec to pexy, including earlier ambulation, more rapid return to normal diet, shorter hospital stay, and lower morbidity (232). Most surgeons believe that there are no differences in recurrence rates between suture and mesh rec to pexy. A Cochrane review performed in 2008 concluded that division of the lateral ligaments was associated with less recurrent prolapse but more pos to perative constipation (233). The authors acknowledged the limitations of their review, which consisted of very few trials with small sample sizes and methodological weakness. A review of seven open and four laparoscopic series involving division of the lateral ligaments revealed a general improvement in fecal incontinence and either no change or worsening of constipation (230). Conversely, there were 15 open and 4 laparoscopic series with preservation of the ligaments that displayed improved continence and a trend to ward reduced constipation. This study suggests that preservation of the lateral ligaments is associated with an improvement in fecal incontinence and constipation symp to ms. Perineal Procedures Perineal procedures are more easily to lerated because they avoid laparo to my. Thus, they are ideal for patients at high risk for perioperative and pos to perative morbidity and mortality. There are basically two perineal procedures: the Delorme procedure and perineal rec to sigmoidec to my (Altemeier operation). Perianal encirclement procedures such as the Thiersch procedure are not recommended because of poor success rates, high recurrence rates, and fecal impaction. The Delorme procedure was first described in 1900 and involves separation of the rectal mucosa from the sphincter and muscularis propria, followed by resection of the rectal mucosa and plication of the distal rectal wall (muscularis propria) (234) (Fig. A review of 10 series found a recurrence rate ranging between 4% and 38% and mortality rates of 0% to 4% (230). The low mortality rates are impressive considering the higher-risk population; however, the recurrence rates make it a less desirable procedure among healthy patients. Fecal incontinence (presumably indicating anal sphincter disruption or denervation), chronic diarrhea, and severe perineal descent are associated with failure of this procedure (235). The Delorme operation may be preferred in cases when the prolapsing segment is shorter than 3 to 4 cm or there is no circumferential full-thickness prolapse, making perineal rec to sigmoidec to my difficult to perform (230,236). After mucosal stripping to the full extent of the prolapse, the circular smooth muscle or the rectum is plicated. Perineal rec to sigmoidec to my (Altemeier operation) has become the perineal procedure of choice (237). Among 12 studies, performance of full thickness excision of the rec to sigmoid was associated with recurrence rates from 0% to 16% and mortality rates of 0% to 5%. Patients generally have minimal pain and a relatively uneventful pos to perative course. Incontinence results are modest at best but seem to improve substantially with the addition of leva to rplasty. The addition of leva to rplasty also appears to decrease the short-term recurrence rate, but there is no significant change in constipation with this procedure (238). Most agree that perineal rec to sigmoidec to my with leva to rplasty is the best procedure for very elderly patients and those with profound comorbidity. This is the preferred approach for patients with incarcerated, strangulated, or even gangrenous prolapsed rectal segment who are not candidates for abdominal rec to pexy. Although there is a general consensus that abdominal rec to pexy is better than perineal rec to sigmoidec to my, there is only one small, prospective, randomized controlled trial comparing these procedures. This study did not have the power to detect a difference in recurrence rates but found that patients undergoing abdominal resection rec to pexy had less fecal incontinence and better physiological results than patients who had perineal rec to sigmoidec to my (233,239).

Because breast cancer presents first as local disease just herbals discount 60 caps ayurslim with mastercard, screening mammography for breast cancer in asymp to matic women can detect small tumors and offer a better prognosis herbals export generic ayurslim 60 caps on line. These tumors had less opportunity to metastasize regionally or systemically; thus women have more options for treatment with reduced to xicity zenith herbals purchase genuine ayurslim. The American Cancer Society published an extensive review of the benefits herbals for hair growth purchase ayurslim cheap, limitations vaadi herbals review buy ayurslim in united states online, and potential harms of screening mammography (35) herbals plant actions cheap ayurslim 60 caps without a prescription. It addresses the role of physical examination, discusses screening in older and high-risk women, and reviews the role of newer technologies. A summary of the guidelines recommends that women of average risk for breast cancer begin mammographic screening at age 40. The rationale for beginning mammographic screening at age 40 is a 24% reduction in mortality in screened populations (28). For women in their 20s and 30s, a clinical breast examination is suggested at least every 3 years, and preferably annually, as part of a well-woman examination. For women older than age 40 years, annual clinical breast examination and mammography are recommended. For older women, recommendations for mammographic screening may be individualized based on the presence of any comorbidities. Chronologic age alone should not be considered a contraindication to mammographic screening as long as a woman is in reasonable health and would be a candidate for breast cancer surgery (35). The American Geriatrics Society recommends annual or at least biennial mammography for women up to age 75 years, and after that age, every 2 to 3 years if the woman has a life expectancy of more than 4 years (36). The natural his to ry of the disease in older women must be balanced against life expectancy as a function of overall health (42). No screening test is perfect, and false-negative imaging studies or benign clinical examinations may lead the patient to an erroneous sense of well-being only to be confronted later with a subsequent cancer. Likewise, a false-positive result can lead to significant anxiety and unnecessary biopsy. Mammographic Abnormalities A mammographic abnormality includes a mass (solid versus cystic), microcalcifications (benign, indeterminate, suspicious), asymmetric density, architectural dis to rtion, and appearance of a new density. Calcifications can be macrocalcifications, which are coarse and usually represent benign degenerative breast conditions. Calcifications associated with breast cancer are clustered pleomorphic microcalcifications; typically five to eight or more calcifications are aggregated in one part of the breast (45). A malignant density usually has irregular or ill-defined borders and may lead to architectural dis to rtion, which may be subtle and difficult to detect in a dense breast. Other mammographic findings suggesting breast cancer are architectural dis to rtion, asymmetric density, skin thickening or retraction, or nipple retraction. Examples of mammographic abnormalities can be found in several electronic sources (46). Known malignancy (a category that is often used for follow-up of a lesion that is undergoing neoadjuvant treatment) the patient should be referred for tissue diagnosis if the report identifies a lesion as a category 4 or 5 (47). A category 0 indicates incomplete evaluation, and further diagnostic studies are required. Category 3 connotes a finding that is most likely benign; a short interval follow-up is recommended, and breast examination by an expert should be considered. Correlation of Findings Biopsy must be performed on patients with a dominant or suspicious mass despite absence of mammographic findings (48). Mammography should be performed before biopsy so other suspicious areas can be noted and the contralateral breast can be checked (Fig. Mammography is never a substitute for biopsy because it may not reveal clinical cancer, especially when it occurs in the dense breast tissue of young women with fibrocystic changes. Mammography is less sensitive in young women with dense breast tissue than in older women, who tend to have fatty breasts, in which mammography can detect at least 90% of malignancies (50). Small tumors, particularly those without calcifications, are more difficult to detect, especially in women with dense breasts. Reliable, portable, computer-enhanced ultrasonography with high-frequency transducers and improved imaging is available to evaluate and treat problems of the breast (52). It is a sensitive, minimally invasive technique that is used frequently to evaluate some breast symp to ms, especially in younger women with dense breast tissue, but is dependent on the availability of a skilled ultrasonographer (53). Breast ultrasonography is not recommended for routine screening, but is being studied as a means to screen women with dense breast tissue (54). Following are indications for breast ultrasonography: Characterization: Palpable abnormality Ambiguous mammographic findings Silicone leak Mass in woman younger than 30 years, lactating, or pregnant Guidance for interventional procedures Possible role for additional imaging in high-risk individuals Ultrasonography is useful in distinguishing benign from malignant lesions identified by mammography (56). Ultrasonography may be especially useful if the patient feels a mass, but the physician cannot detect an abnormality and the mammogram does not disclose one. It may identify cancers in the dense breast tissue of premenopausal women, but it is usually used to distinguish a benign cyst from a solid tumor. Ultrasonography cannot reliably detect microcalcifications, and it is not as useful as mammography in assessing women with fatty breasts. Handheld or real-time ultrasonography is 95% to 100% accurate in differentiating solid masses from cysts (57). This finding is of limited clinical value because a dominant mass should be evaluated by biopsy, and a cystic mass can be studied by needle aspiration, which is far less expensive than ultrasonography. Rarely ultrasonography may identify a small cancer within a cyst, an intracystic carcinoma. Magnetic Resonance Imaging Magnetic resonance imaging may be of value in assessing breast lesions of an indeterminate nature detected by clinical and mammographic examination or occurring in patients who have implants (58). It tends to be highly sensitive but not specific, leading to biopsies of benign lesions. Image enhancement with gadolinium discriminates between benign and malignant lesions with varying degrees of accuracy. A scar can easily be distinguished from recurrent tumor based on the evaluation and diminution of the scar over time. Some scars do not resolve rapidly and are confused with cancer or, more commonly, with recurrent cancer after breast-conserving surgery and whole breast irradiation. Although not specifically approved for the initial diagnosis of breast cancer or for staging the axilla, it can be useful in patients with advanced disease (59,63). This technique is used to identify occult breast lesions with positive axillary lymph nodes (59). Breast Tissue Evaluation: His to logy and Cy to logy the safest course is tissue or cy to logic biopsy evaluation of all dominant masses found on physical examination and, in the absence of a mass, evaluation of suspicious lesions shown by breast imaging. Investiga to rs of the Fifth Radiologic Diagnostic Oncology Group demonstrated that image-guided biopsy of breast lesions provides high diagnostic accuracy. About 30% of lesions suspected to be cancer prove on biopsy to be benign, and about 15% of lesions believed to be benign prove to be malignant (23). Dominant masses or suspicious nonpalpable breast lesions require his to pathological examination. His to logic or cy to logic diagnosis should be obtained before the decision is made to moni to r a breast mass (69). An exception may be a premenopausal woman with a nonsuspicious mass presumed to be fibrocystic disease. An apparently fibrocystic lesion that does not completely resolve within several menstrual cycles should be sampled for biopsy. Any mass in a postmenopausal woman who is not taking estrogen therapy should be presumed to be malignant. Some clinicians will moni to r a mass when results of the clinical diagnosis, breast imaging studies, and cy to logic studies are all in agreement, such as with fibroadenoma. Some surgeons excise lesions when the sampling technique shows only fibrocystic disease. Simultaneous evaluation of a breast mass using clinical breast examination, radiography, and needle biopsy can lower the risk of missing cancer to only 1%, effectively reducing the rate of diagnostic failure and increasing the quality of patient care (70). Treatment should not be determined based on results of physical examination and mammography alone, in the absence of biopsy results. This two-step approach allows patients to adjust to the diagnosis of cancer, carefully consider alternative forms of therapy, and seek a second opinion. Studies show no adverse effect from the 1 to 2-week delay associated with the two-step procedure (71). Because cancer is found in the minority of patients who require biopsy for diagnosis of a breast mass, definitive treatment should not be undertaken without an unequivocal his to logic diagnosis of cancer. It can be performed easily, with no morbidity, and is much less expensive than excisional or open biopsy. It requires the availability of a pathologist skilled in the cy to logic diagnosis of breast cancer to interpret the results, and it is subject to sampling problems, particularly when lesions are deep. Cy to logic diagnoses must be correlated with clinical and imaging findings to achieve triple-test concordance and to decrease the false-negative rate (73). Core Needle Biopsy A core of tissue can be obtained from palpable lesions using a large cutting needle (76). Image-guided large-core needle biopsy is a reliable diagnostic alternative to surgical excision of suspicious nonpalpable breast lesions (77). As in the case of any needle biopsy, the main drawback is false-negative findings caused by improper positioning of the needle. False-negative findings may be reduced if core biopsy is performed with ultrasonographic guidance. Its utility is reserved for when the results of needle biopsy are nondiagnostic or equivocal. His to logic Analysis His to logic evaluation with hema to xylin and eosin (H&E) staining confirms benign or malignant disease. Images of benign and malignant breast lesions can be viewed through the Internet Pathology Labora to ry for Medical Education (79). Assessment of prognostic fac to rs, tumor grade; estrogen, progesterone, her-2/neu recep to r status; and proliferative indices is performed on paraffin-fixed tissue by immunohis to chemistry (78). Ductal Lavage Cy to logy Ductal lavage using a microcatheter is a modality that was investigated in high-risk women (81). A duct that yields fluid is cannulated with a microcatheter, and 10 to 20 mL of saline are introduced in 2 to 4-mL increments. The cy to logic assessment of a sample obtained by ductal lavage is more sensitive than that of nipple aspiration. Ductal lavage performed to identify abnormal cells is not an effective to ol in detecting breast cancer and is rarely performed (81). Benign Breast Conditions Benign breast disorders account for most breast problems. These conditions are frequently considered in the context of excluding breast cancer and often are unrecognized for their own associated morbidity (82). To provide appropriate management, it is important to consider benign breast disorders from four aspects: (i) clinical picture, (ii) medical significance, (iii) treatment intervention, and (iv) pathologic etiology (83). It includes symp to ms, his to logy, endocrine state, and pathogenesis in a progression from a normal to a disease state. Most benign breast conditions arise from normal changes in breast development, hormone cycling, and reproductive evolution (82). During the mature reproductive period (25 to 40 years), cyclic hormonal changes affect glandular tissue and stroma. The third phase is involution of lobules and ducts or turnover of epithelia, which occurs during ages 35 to 55 years. Those associated with ductal involution are duct dilation (nipple discharge) and periductal fibrosis (nipple retraction), and those with epithelial turnover are mild hyperplasia (pathologic description). Disease conditions with increased epithelial turnover are epithelial hyperplasias with atypia. Breasts are under endocrine control and show a wide range of appearances during reproductive life. Fibrocystic Change Fibrocystic change, the most common lesion of the breast, is an imprecise term that covers a spectrum of clinical signs, symp to ms, and his to logic changes (76). The term refers to a his to logic picture of fibrosis, cyst formation, and epithelial hyperplasia (83). Cysts arise from the breast lobules and are an aberration of normal breast involution (82). Macroscopic cysts occur in approximately 7% of women, and microscopic, nonpalpable cysts occur in about 40% of women (84). It is common in women 35 to 55 years of age, but rare in postmenopausal women not taking hormone therapy. This finding is supported by the observation that it is present bilaterally, increased in the perimenopausal age group, and responsive to endocrine therapy (85). In essence, a diagnosis of fibrocystic change can lead to significant patient anxiety but is of little clinical significance as long as malignancy is excluded (86). Cyst Fluid Analysis Investiga to rs examined the electrolyte and protein content of cyst fluid, but this is of little significance in the clinical management of fibrocystic disease. The potassium- to -sodium ratio is a marker that may be used to distinguish cyst subtypes (87). The role of this serine protease in proliferative breast disease is not fully unders to od. Clinical Findings in Fibrocystic Disease Fibrocystic changes may produce an asymp to matic mass that is smooth, mobile, and potentially compressible. Fibrocystic change is more often accompanied by pain or tenderness and sometimes nipple discharge. In many cases, discomfort coincides with the premenstrual phase of the cycle, when the cysts tend to enlarge. Fluctuations in size and rapid appearance or disappearance of a breast mass are common.
