From neurological diseases such as Guillainthese sites, infection can spread via Barre syndrome, and, rarely, a lupusthe bloodstream to produce metastatic like syndrome. Therefore, it is not surprising that B-cell maturation beyond the pre-B-cell mutations in each of these elements causes stage found in the bone marrow, requires early-onset antibody deficiency associated signals received through the pre-B-cell with lack of circulating B cells. This condition is called X-linked antibody (this process is called affinity agammaglobulinemia, which was the first maturation). Through these processes, immunodeficiency to be described in 1952 memory B cells are generated within by Colonel Ogden Bruton. If the T-cell immunity, they also suffer from point mutation(s) result in increased bindopportunistic infections characteristic of ing affinity to the inducing antigen, the BT-cell deficiency.

Although ischemic events do happen and are therefore important to discuss erectile dysfunction treatment success rate buy cialis 10mg free shipping, they seem to be exceptionally rare and represent a small percentage of complications in individual clinical practices. However, the true incidence of this complication is unknown because of underreporting by clinicians. Typical clinical findings include skin blanching, livedo reticularis, slow capillary refill, and dusky blue-red discoloration, followed a few days later by blister formation and finally tissue slough. Mainstays of treatment (apart from avoidance by meticulous technique) are prompt recognition, immediate treatment with hyaluronidase, topical nitropaste under occlusion, oral acetylsalicylic acid (aspirin), warm compresses, and vigorous massage. Secondary lines of treatment may involve intra-arterial hyaluronidase, hyperbaric oxygen therapy, and ancillary vasodilating agents such as prostaglandin E1.

As with all transport, finally resulting in vascular obstruction, ischcomplications, prevention should be the primary goal. Clearly, dermal fillers other referral sources in his capacity as medical director. Escalating pain is felt in areas affected by ischemia and Absence of pain is therefore unreliable in the early phases of injury, if local may not respond to treatment with analgesics. Pallor or blanching phase Blanching of skin may occur immediately after intra-arterial Not pathognomonic. May also be seen if epinephrine is included in the filler injection as a temporary phase. Pallor from epinephrine (in the anesthetic formulation) is due to arterial contraction and generally lasts 5 to 10 minutes, but this is highly variable. Livedo phase Blotchy reddishor blue-mottled discoloration typically Not pathognomonic. Partial occlusion, or the presence of collateral circulation, follows blanching phase but progresses to bluish can modify the clinical appearance. Also, skin color may be altered by discoloration, as oxygen is depleted in cases of ambient temperature and modulated by patient sensitivity to cold. Slow capillary refill Digital compression of affected area shows slow blood Return of normal pink color after 1 or 2 seconds is considered normal. Blue or gray-blue phase With local tissue oxygen depletion, the deep blue of Metabolic activity in the affected tissues consumes all available oxygen in deoxygenated blood predominates. Demarcation phase In the advanced state of ischemia that has progressed to Localized tissue necrosis is a late sign, followed by tissue slough, often necrosis, a distinct margin of hyperemia surrounds a involving several layers of tissues (not just dermis). Epithelial integrity is lost, and results then heals slowly by secondary intention. Repair and remodeling phase Final stages after slough of necrotic tissue; inflammation Healing occurs by secondary intent, as epithelial cells migrate and mature to subsides, and tissue repair and remodeling occurs. Some products are more likely to promote immediate blood clotting within blood vessels (such as collagen); others may cause simple mechanical obstruction of vessels without excitation of the complement cascade and without inciting an acute inflammatory reaction (eg, pure fillers). The clinical presentation of dermal complications involves tissue anoxia and possible progresischemia may involve livedo reticularis, erythromelalgia, sion to necrosis (Table 1). The essential component com62 mon within this group is accidental intravascular filler ulceration, or frank dermal infarct. Livedo (from the Latin lividus, of bluish or leaden color) reticularis (from injection into the arterial system, resulting ultimately in the Latin root rete, net) appears as a macular, violaceous, obstruction of the arterial blood supply. Depending on the net-like skin discoloration, which is usually a benign effect nature and quantity of the filler agent, outcomes of differ63 ing severity are seen. In cholesterol 68-70 emboli proximal to the skin, crystals are typically found in Oroklini, Cyprus). This same pathology has been observed with der66,67 4-18,20-52,71-79 mal fillers. Needle aspiration may or may not show any nasolabial fold, the nose, and glabellar areas.

Although aspiration prior to injection is good arterial blood through a narrow-gauge long needle is an practice, viscous filler material may not allow arterial blood to flash unreliable indicator. Previous scarring Deep tissue scars may stabilize and fix arteries in place, In fatty tissues, thicker walled arteries may roll out of the way when making them easier to penetrate with small sharp prodded by larger needles, as attested to by those experienced in needles. Fixation by scarring holds the vessel in place, arteries pass through bony foramina or deep fascial making it easier to penetrate. Larger diameter cannulae with a rounded tip are less likely treatments in the same area, for example). Composition of filler material used Permanent fillers have no means of dissolving the material. Risk factors associated with this phenomirreversible progression to frank necrosis of the involved tisenon are shown in Table 2. A more likely possibility is that some fillers, because of Arterial vessels traverse many of the areas commonly particle size, are able to travel further down vascular pathtreated with fillers. For example, the labial artery is very ways, to the point where the obstruction occurs. The human face is dental intra-arterial injection; subsequently, the material travendowed with a rich vascular network, and given the els with the blood throughout the arterial system, being numerous collaterals and anastomoses present between carried to progressively smaller vessels. Note proximity of the artery to buccal mucosa, posterior to the wet-dry line of the lower lip. This area is commonly injected when trying to evert the red lip during augmentation with hyaluronic acid fillers. This mechanism may explain puzzling may cause limited obstruction that can be bypassed via cases of distant necrosis in adjacent vascular areas. The Depending on the amount of material injected; its viscosclinical effect seen will depend on the presence or absence of ity, cohesion, and other rheological properties; as well as adequate collateral circulation in the target tissues. Thereby, the product moves through more proximal collateral blood vessels and then to regions the perforating branches from subcutaneous fat. The rich vascular network the largest proportion of vessels within the papillary derbypasses the obstruction so completely that the accident mis, postcapillary venules constitute the site both where never manifests itself clinically. The lower plexus is found from the hypodermis create small conical zones, centered 84,85 at the dermal-subcutaneous interface, rising directly from on the feeding vessels from the lower plexus. When DeLorenzi 589 gels and many other dermal fillers would not be able to pass through such small vessels. Differences in the structure of these gels may make a difference in their effectiveness for arterial occlusion. In contrast, monophasic products (eg, Juvederm, Allergan, Inc, Irvine, California; Teyosal, Clarion Medical, Cambridge, Ontario, Canada), which consist of highly cohesive gels, tend to coalesce into a mound in vitro. In other words, such products do not spread out eas86,87 ily; they tend to retract. Nevertheless, there are definite distinctions between filler products; as evidenced by published case reports, their individual composition can and does make a clinical difference in the severity of obstruction and the likelihood of recovery with treatment. A video demonstrating the differences in the in vitro behavior of the 2 product types, each of which has applicaFigure 3.

All that can be said at this point is that each product zones from the superficial to the deep plexuses. For examcan and does differ in its tendency to cause vascular ple, the livedo reticularis pattern often present in cases of obstruction. The clinical pattern observed is thus due to blood stasis in the dermal venules, probably a much more important factor in vascular and the bluish discoloration results from the dusky redobstruction. The most severe cases have not uncommonly blue color of desaturated blood, optically filtered by the occurred from the accidental, catastrophic release of a dermis and epidermis. Obviously, the end result of Note the branch point is dependent on the quantity of intra-arterial injection must be obstruction. If circulation is restored, skin usually exhibits reactive hyperemia (blushing), followed by return to normalcy. If vascular occlusion is significant, skin may show livedo, followed by other signs of ischemia. Bluish skin with extremely or, alternatively, the good pathway toward restoration, fast capillary refill may signal venous insufficiency, and reactivity, and bounding return of the circulation. The latslow capillary refill with dusky or blue-black color may ter is sometimes variably associated with ischemia-reperindicate arterial insufficiency. Clinical examination of patients with arterial occlusion Skin blanching immediately following accidental intramay demonstrate slow capillary refill, often associated with arterial injection of filler is occasionally seen but is by no skin extremely tender to the touch (Figure 5). However, given the small quantity injected in the area, facially in response to a filler injection, it appears to be a she did not have any lasting ill effects. Localized color changes in the affected areas issue about whether it is safer to inject larger quantities of should raise the index of suspicion of vascular compromaterial into fewer areas or to inject tiny amounts into mise. This question cannot be answered timing (Table 3), deserves the greatest scrutiny, with the at present because of lack of clinical or laboratory data. Despite some limitations, capillary refill an artery will usually not have any significant repercustime has been used as a clinical test of perfusion for sions. Therefore, on balance, it is likely safer practice to decades, especially for children.

This 62-year-old woman was injected in the nasolabial fold areas with calcium hydroxylapatite (Radiesse, Merz Aesthetics, San Mateo, California) compounded with 0. This patient did not have any adverse consequences and made an uneventful recovery. These studies also support the hypothesis that intra-arterial injection, as opposed to external vascular compression, is the root cause of decreased blood flow. Although conceivable that in some rare circumstances, external pressure from a filler agent can cause decreased blood flow, this does not appear to be the typical primary mechanism. In fact, trying purposefully to recreate such results in preliminary investigations with a rabbit ear model failed: only direct intra-arterial injection of dermal filler resulted in 97 cutaneous necrosis.

Inflammatory Stage a hematoma (localized blood collection) forms within the fracture site during the first few hours and days. Inflammatory cells infiltrate the bone, which results in the formation of granulation tissue (which is important in healing and repair), vascular tissue (for blood delivery to the new bone), and immature tissue (which will specialize to form a bridge of tough connective tissue). The cells of the body that are capable of changing into bone cells are activated or fired up to do so, and they start laying down new bone tissue. The hardening of the cartilage begins at each end of the fracture and sweeps toward the center. Remodelling Stage this is the stage where the body changes the weak bone material into strong bone material. Because this new material is so strong, the body does not need a lot of it, and it will remodel the fracture callus down to normal sized bone. The bone should be restored to its original shape, structure, and mechanical strength. The third and fourth sections show the callus and bone formation of the repair stage.

In the early 1990s, the Centers for Disease Control estimated the rate of ectopic pregnancy to be about 2% of all pregnancies [1]. A major risk factor for ectopic pregnancy is pelvic infammatory disease [3], and other high-risk factors include a previous ectopic pregnancy and tubal surgery. Among those, 70% of tubal ectopic pregnancies occur within the ampullary portion, followed by the isthmus, fmbriae, and How to cite this article: interstitial tubal segments [4]. Diagnosing ectopic pregnancy in the emergency outside of the fallopian tubes, including the ovary, cesarean section scars, cervix, and peritoneal cavity. This is of the for these patients includes both transabdominal and transvaginal utmost importance in patients without an identifable intrauterine evaluation. It includes a wider field of view of the pelvis and Clinical and Diagnostic Approach provides better visualization of the uterine fundus and superiorly positioned adnexa. Transabdominal sagittal and transverse views of the pelvis demonstrate a normal uterus and urinary bladder. Transvaginal sagittal and transverse views allow better visualization of the endometrium. No embryo is yet visualized in this patient with an early pregnancy, at approximately 5-6 weeks. The bilateral adnexae must adnexal structures essentially excludes the possibility of an ectopic be carefully scrutinized, as ectopic pregnancy can have variable, pregnancy [6]. Color Doppler often shows a ring of demonstrate various degrees of echogenicity depending on the age circumferential vascularity (Fig. Visualization of an extrauterine gestational sac with an embryo Tubal ectopic pregnancy can be also seen as an echogenic ring (Fig. This is the Additional sonographic findings are associated with ectopic second most common sign of ectopic pregnancy and has a 95% pregnancy. While free fuid is a nonspecifc fnding that can be seen both physiologically and in other pathologies, a moderate or large volume of free fuid greater than expected for a physiologic volume and complexity of the free fuid, with foating debris, blood products, and/or organized blood clots (Fig. A so-called pseudogestational sac represents a small amount of intrauterine fluid (Fig. Real-time observation of this phenomenon will often show a shifting of the fuid as the exam progresses, unlike the fxed position of a true intrauterine gestational sac. In this 21-year-old woman with positive serum pregnancy test and vaginal bleeding, a Other Rare Ectopic Pregnancies complex echogenic mass (arrow) is seen in the right adnexa, which separates from the right ovary (open arrow) with applied pressure In an interstitial ectopic pregnancy, the implantation takes place during transvaginal ultrasound. The echogenic adnexal mass is in the interstitial portion of the fallopian tube, and this accounts representative of a hematoma at the site of ectopic implantation. In this 20-year-old woman with a positive pregnancy test presenting to the emergency department with pelvic pain and vaginal spotting, there is an adnexal mass with echogenic ring (arrow). A color Doppler image of the right adnexa shows increased vascularity in the echogenic ring. The patient was diagnosed with ectopic pregnancy based on a clinical and sonographic assessment and was treated successfully with methotrexate. The diagnosis is suggested when a gestational sac of a prior cesarean section scar. Severe myometrial thinning or is visualized high in the fundus surrounded by a thin layer of complete absence of the myometrium between the gestational sac myometrium measuring less than 5 mm [11]. Scar ectopic pregnancies pose a is an echogenic line extending from the endometrium to the ectopic signifcantly increased risk for uterine rupture. In this 25-year-old woman with a positive pregnancy test and vaginal bleeding, there was a gestational sac containing an embryo in the left adnexa, outside the left ovary. The M-mode ultrasound of the embryo in the left adnexa shows a fetal heart rate of 170 beats per minute. In this 22-year-old emergency department with pelvic pain and a positive pregnancy woman with a prior history of ectopic pregnancy presenting to the test, simple free fuid was found in the pelvic cul-de-sac. The patient emergency department with pelvic pain and a positive pregnancy also had an echogenic left adnexal mass (not included in this fgure), test, a large volume of complex free fuid with internal echogenicity which was confrmed to be an ectopic pregnancy intraoperatively. A 28-year-old woman with a positive pregnancy test presented to the emergency department with right lower quadrant pain. A small amount of free fuid is seen within the endometrial cavity, without evidence of a yolk sac or embryo (arrow). It is irregularly-shaped and centrally located, rather than in the eccentric location often seen with a normal gestational sac. There is a right adnexal mass with an echogenic ring (open arrow), suspicious for ectopic pregnancy. Cervical ectopic pregnancy occurs in fewer than 1% of ectopic [15], compared to a trivial incidence among patients who conceive pregnancies [11]. Timely diagnosis and treatment may be within the cervical stroma, usually in an eccentric position. The critical not only for reducing maternal morbidity and mortality, but resulting cervical distention results in an hourglass-shaped uterus. Ovarian ectopic pregnancy refers to the intraovarian implantation of a gestational sac and may account for up to 3% of ectopic Complications of Ectopic Pregnancy pregnancies [4]. However, an anechoic or even in life-threatening hemorrhage and often requires emergent surgery. It is most often located in the pouch of Douglas Methotrexate has been proven to be a safe and effective treatment (rectouterine space), but it can be anywhere within the peritoneal for ectopic pregnancy [18]. It is usually a round, thick-walled structure, often cystic, with these sonographic fndings usually represent the expected resolution varying internal echogenicity depending on presence of hemorrhage of the ectopic pregnancy. This is a 31-year-old woman who has positive but declining serial fi-human chorionic gonadotropin levels. There is a heterogeneous echogenic mass (arrow) in the left adnexa adjacent to the left ovary (open arrow). The patient was diagnosed with left tubal ectopic pregnancy and was started on medical treatment with methotrexate. On a follow-up pelvic ultrasound 10 days after initiation of methotrexate treatment, there is interval enlargement of the left tubal ectopic pregnancy (arrow) due to surrounding hemorrhage and edema. This figure represents a 32-year-old woman who presented to the emergency department with lower abdominal pain. There is an intraovarian cystic structure with echogenic ring and internal debris (indicated with cross-hair markings). A color Doppler ultrasonography of the same structure shows signifcant peripheral vascularity, which is often seen in a corpus luteum. Bowel loops appearances, but are usually seen as a focal hyperechoic mass in the can appear as a mass-like structure with distinct walls and mural ovary. Real-time imaging by the radiologist or Cine images provided by the technologist can be very helpful in differentiating the bowel from an ectopic pregnancy by demonstrating peristalsis in the bowel loops. Conclusion Ectopic pregnancy is the leading cause of pregnancy-related maternal death during the frst trimester [1]. In the light of the increased use of medical management and improved outcomes, the early diagnosis and timely initiation of treatment have become more critical in decreasing maternal morbidity and mortality by preventing complications and avoiding the need for surgical Dist 1. This is a 17-year-old girl presenting to the emergency department with pelvic pain. Multiple thin echogenic bands, also known as a dot-dash pattern (open arrow), are seen in parts of the mass, representing hair follicles. This fgure represents a 28-year-old woman who presented to the emergency department with right lower quadrant pain and a positive pregnancy test. The sagittal view of the right adnexa shows a hemorrhagic cyst in the right ovary; otherwise, no defnite adnexal mass can be seen. A transverse view of the right adnexa did not demonstrate a defnitive mass in the right adnexa. At the time of the study, nonspecifc echogenicity in the right adnexa was interpreted as bowel loops.

Accordingly moderated nominal group processes as well as structured consensus conferences took place [1]. As part of this process a formal vote was taken on the recommendations by all mandate holders. The result of each vote (degree of consensus) is categorized according to Table 4 for each recommendation. Three degrees of recommendation are distinguished in this guideline (see Table 4) which also reflect the formulation of the recommendations. Statements Statements are interpretations or comments on specific issues and problems without direct call for action. They are passed in a formal consensus process according to the procedure for recommendations. Usually these recommendations address fields of good clinical practice for which no scientific studies are necessary or to be expected. For the grading of expert consensus there are no symbols, the strength of recommendation is a result of the wording (shall/should/can) according to Table 4Fehler! Independence and Declaration of Possible Conflict of Interest the drafting and update of the guideline was performed independently of the funding organization, the German cancer aid (Deutsche Krebshilfe). The mandate holders and experts are to be thanked for their voluntary work without which the formulation of the S3-guideline would not have been possible. All members of the guideline group gave a written statement concerning possible conflicts of interest. The relevance of the conflicts of interest for the guideline was discussed in several meetings (kick-off meeting and consensus conference) and by email. In the update 20102013 (Version 1) the conflicts of interest were reviewed and evaluated by the coordinators. Kolligs the authorized conflict of interest representative performed the review and evaluation of the disclosed conflicts of interest. Kolligs the guideline group decided that there would be no restrictions for any delegate in the voting process as inappropriate distortion of guideline recommendations was considered highly unlikely. The reason for this was the methodological approach as well as the multidisciplinary composition of the guideline group. The formal consensus process and interdisciplinary drafting of the guideline are additional instruments to minimize interference by industry. Editorial information Gender neutral formulations Solely for better legibility no gender neutral formulations are used. Participatory decision making All recommendations in the guideline should be seen as recommendations, which are made using a participatory decision making process between physicians and patients and their family. Evidence-based Recommendation 2013 Grade of To reduce the risk of colorectal cancer regular physical activity is recommended. Recommendation B Level of Evidence Evidence from update literature search1: [2-13] 2a Strong consensus 3. Evidence-based Recommendation 2013 Grade of To reduce the risk of colorectal cancer weight reduction is recommended for Recommendation overweight persons. B Level of Evidence Evidence from update literature search: [2, 9, 14-19] 2a Strong consensus 3. Evidence-based Recommendation 2013 Grade of It is recommended to refrain from smoking. Already 30 to 60 minutes of moderate physical activity per day is associated with a lower cancer risk [2-13]. The risk of colon cancer was up to twice as high in overweight persons especially with truncal obesity [19] It is not clear whether the risk increase is due to obesity, altered hormone levels, increased calorie uptake, or absence of physical activity [2, 9, 14-19]. Smoking is associated with a risk for colon adenomas that is twice as high and an increased risk of cancer [2, 11, 20-26]. A "healthy" diet was designated by the authors as including a high consumption of fruit and vegetables as well as reduced intake of red and processed meat. In contrast, an "unhealthy" was characterized by a large uptake of red and processed meat, potatoes, and refined starch [27]. Therefore, despite the outlined relationships, currently no specific diet recommendations can be made. It should also be stressed here that a diet that does not cause weight gain is recommended (see Chapter 3. Recommendation B evel of Evidence Evidence from update literature search: [34-38] 2a Consensus Background Despite controversial data, the evidence is sufficient to recommend a fiber rich diet of 30 g/day [34-38]. A current British study that summarizes data from seven cohort studies showed an inverse correlation between fiber uptake and cancer risk. The comparison of the daily fiber consumption of 10 and 24 g in this study demonstrated that a higher consumption was associated with a colon cancer risk reduction of 30 % [34]. In another study which summarized 13 prospective cohort studies showed similar results. Although the pooling project of prospective studies of diet and cancer demonstrated an even greater range between the lowest and highest quintile of fiber uptake, a significant inverse correlation was observed between fiber consumption and cancer risk after age-adjusted analysis, but not after adjustment according to other diet related risk factors [37]. These limited positive data may be due to the fact that the recording of the fiber consumption was merely done at the start of the study, which may reflect an incorrect long-term uptake. Despite the limited results, the remaining statements are very robust, because they are based on a large collective. Abstinent persons and persons who drink little alcohol have a significantly lower cancer risk [39-42]. A meta-analysis of 14 prospective cohort studies showed that already an alcohol intake of 100 g per week is associated with a 15 % increase in colon as well as rectal cancer risk [42]. The risk correlates with the amount of alcohol consumed not with the type of alcoholic beverage [40]. Evidence-based Recommendation 2013 Grade of Red or processed meat should only be consumed in small amounts (not daily). The positive association is most likely due to the processing and preparation as demonstrated by data of the Prostate, lung, colorectal, and ovarian cancer trials. Evidence-based Statement 2013 Level of Evidence No recommendation can be given about an increased fish consumption. A comparison of the lowest and highest weekly fish uptake showed that higher consumption is associated with a 12 % lower cancer risk. The greater the difference between the lowest and highest fish uptake was, the more pronounced the correlation became [48]. This is probably due to the different amounts of fish that were consumed in the different studies [43, 45, 46, 48-50]. However, it is unknown which components (fiber, secondary plant products) have this protective effect. Consensus Background It has been repeatedly discussed whether food preparation or the proportion of potentially toxic fatty acids. An effect resulting from cofactors such as intake of red meat or type of preparation cannot be sufficiently differentiated [31, 32, 38, 48, 58-60]. Recommendation 2013 Grade of At this time there are no verified data on the effective prevention of Recommendation colorectal cancer by micronutrients. Evidence basis 2b vitamins de Novo: [65] 3b including carotene de Novo: [65] 3b vitamin A de Novo: [65] 4. A moderate clinically non-relevant inhibitory effect on the recurrence of colon adenomas was observed for calcium [73-75]. A meta-analysis [65] demonstrated, on the contrary, that supplementation of the aforementioned vitamins, alone or in combination was associated with an increased general mortality. The correlation of low selenium levels in serum and an increased adenoma risk is not sufficient to make a recommendation on selenium supplementation [77, 78]. However, all three studies showed a pronounced increase in cardiovascular morbidity. Prospective studies on the primary prevention of adenomas using ursodesoxycholic acid do not exist. Preventive Services Task Force Guideline on the use of hormone therapy in postmenopausal women [88] and the guideline Hormone Therapy in Periand Postmenopause of the German Society for Gynecology and Obstetrics [91]. Consensus-based Recommendation 2013 Colorectal cancer screening should begin at the age of 50 for asymptomatic persons. A prospective colonoscopy study showed that there was a lower rate of advanced adenomas among 40 to 49 year old subjects (3. There are no prospective studies concerning an age limit for colorectal cancer screening. In another study the relative five-year survival rate after curative operations of colorectal cancer for patients over 74 years of age were comparable with patients aged 50 to 74 [99]. There are insufficient data on the benefit/risk ratio for colorectal cancer screening in different age groups. Only endoscopic methods are diagnostic as well as therapeutic methods and have the advantage that they can detect non-bleeding cancer and adenomas with high sensitivity. By removing adenomas, the development of cancer can be effectively prevented (interruption of the adenoma-carcinoma sequence) [100, 101]. This was particularly due to the clearly higher sensitivity for advanced adenomas. Colonoscopies should be performed according to the German Prevention Guidelines 3 including a digital rectal examination. Large cohorts including from Germany showed colonoscopies can detect a large number of cancer at an early stage as well as adenomas in the whole colon [98]. In Germany, about 1/3 of the detected cancer in screening colonoscopies are located proximal to the colon descendens [98]. A diagnosis of neoplasias using sigmoidoscopy would have been impossible in these patients. However, the effect in the proximal colon seems to be smaller than in the distal colon [113-115]. The colonoscopy complication rate in a German study with volunteers was very low [116]. However, it is likely that not all complications were detected, because late complications were only incompletely recorded. Case control studies indicate that after a negative colonoscopy the cancer risk remains very low even after more than 10 years [113, 119]. It is very important that the colonoscopy is performed with the best possible quality. Evidence-based Recommendation 2013 Grade of Quality assured sigmoidoscopies should be offered as a screening measure to Recommendation those who refuse a colonoscopy. An English randomized study comparing a single sigmoidoscopy to no screening after a follow-up of 11. However, it should be taken into consideration that not all sections of the colon can be viewed using sigmoidoscopies. In accordance, a sigmoidoscopy study showed that the incidence of proximal cancer was not affected. The protective effect of sigmoidoscopies for distal neoplasias appears to last for 6 to 10 years [112, 123], and in one study even as long as 16 years [124]. However, a study with 9,417 subjects who underwent a sigmoidoscopy 3 years after a negative one showed advanced adenoma or cancer in the distal colon in 0. Another study in 2,146 participants with negative sigmoidoscopies compared screening/follow-up intervals of 3 and 5 years [126]. It should be performed before sigmoidoscopy, because a positive test requires a colonoscopy and, thus, an additional sigmoidoscopy can be avoided. However, it should be considered that currently in Germany sigmoidoscopies are not covered by the health insurance catalogue of benefits and, thus, they cannot be charged. Furthermore, in contrast to screening colonoscopies no quality assurance measures are established for sigmoidoscopies. In England, a requirement for the participation in a sigmoidoscopy study was at least 50 supervised and 100 independent sigmoidoscopies [109]. The colon depth that was reached, the quality of colon preparation, and the results were recorded.
