But when in doubt, if readily available, and in the absence of clinical strangulation, it may be help ful. Although controversial, some would attempt reduc tion of intussusception when there are no external signs of ischemia or malignan 188 Moshe Schein cy and if after reduction no leading point is found. You should first attempt to obtain information about the findings at previous laparotomy. The more advanced the cancer then, the higher the prob ability that the current obstruction is malignant. Clinically, cachexia, ascites or an abdominal mass suggests diffuse carcinomatosis. On the one hand, one wishes to relieve the obstruction and offer the patient a further spell of quality life. On the other hand, one tries to spare a terminal patient an unnecessary operation. In the absence of stigmata of advanced disease, surgery for complete obstruction is justifiable. In many instances adhesions may be found; in others, a bowel segment obstructed by local spread or metastases can be bypassed. There is also the uncertainty about the obstruction being malignant or adhesive in nature. When forced to operate for complete obstruction, one finds irradiated loops of bowel glued or welded together and onto adjacent structures. Accidental enterotomies are frequent, difficult to repair, and commonly result in postoperative fistulas. Short involved segments of bowel are best resected, but when longer segments are encountered, usually stuck in the pelvis, it is safest to bail out with an entero-enteric or entero-colic bypass. Attempts at preventing subsequent episodes with bowel or mesentery plication or long tube stenting are recommended by some. If you begin an operation expecting a quick and easy procedure and are then confronted by a nightmare abdomen the first thing you must do is reset your mental clock. Failure to do this may mean that you will attempt to rush the procedure and this inevitably leads to disaster with multiple inadvertent entero tomies, peritoneal contamination and ultimately an even longer and more danger ous procedure. When you enter such a disastrous abdomen unexpectedly, tell every one immediately than the procedure is now going to take a few hours while you unravel all the loops necessary to get at the problem and fix it. Gallstone Ileus Gallstone ileus develops typically in elderly patients with longstanding cholelithiasis. You will never miss the diagnosis once you habitually and obsessively search for air in the bile ducts on any plain abdominal X-ray you order (Chap. The air enters the bile duct via the entero-cholecystic fistula created by the eroding gallstone. The aim is therefore to operate only when necessary, but not to delay a necessary operation. The only thing predictable about small bowel obstruction is its unpre dictability. In spite of this, surgeons are frequently confronted by acute groin hernias and it is important to know how to deal with them. A word about terminology:groin hernias, inguinal or femoral, may be describ ed as reducible, irreducible, incarcerated, strangulated, obstructed. This terminology can be confusing and the words, which have come to mean different things to dif ferent people, are much less important than the concepts that underlie the recogni tion and management of acute hernia problems. The important concept to be grasped is that any hernia that becomes painful, inflamed, tender and is not readily reducible should be regarded as a surgical emergency. Presentation Patients may present acutely in one of two ways: Symptoms and signs related directly to the hernia itself Abdominal symptoms and signs, which at first may not seem to be related to a hernia the first mode of presentation usually means pain and tenderness in the irreducible and tense hernia. Treated at home for several days by the primary care physician as a case of gastro-enteritis she eventually comes under the care of the surgeons due to intractable emesis. It is surprisingly easy in these circumstances to miss the small femoral hernia barely palpable in the groin, trapping just enough small bowel as is required to 192 Paul N. No abdominal symptoms or signs are present and the plain abdominal radiographs are non-diagnostic. A careful search must be made for them in all cases of actual or suspected intestinal obstruction. This may mean meticulous, prolonged and dis agreeable palpation of groins which have not seen the light of day, let alone soap and water, for a long time. In most cases, however, the diagnosis is obvious with a clas sical bowel obstruction and a hernia stuck in the scrotum. Because the intestinal lumen is not completely blocked, presentation is delayed and non-specific. Preparation Surgery for acute groin hernia problems should be carried out without undue delay, but these patients must not be rushed to surgery without careful assessment and preparation (Chap. As we suggested earlier, some patients may be in need of quite a bit of resuscitation on admission to hospital. Opiate analgesia and bed rest with the foot of the bed slightly elevated may successfully manage a painful obstructed hernia of short duration. Gentle attempts at reduction of such a hernia are justified once the analgesics have taken effect. Even if a bowel resection is re quired it is possible to deliver sufficient length of intestine through the inguinal canal to carry this out. The main difference in dissection in an emergency hernia operation compared to an elective procedure is the moment at which the hernial sac is opened. In the emergency situation the hernia will often reduce spontaneously as soon as the con stricting ring is divided. The site of constriction may be the superficial inguinal ring, in which case the hernia reduces when external oblique is opened. It is recommen ded, therefore, that the sac be opened and the contents grasped for later inspection before the constricting tissues are released. If the hernia reduces before the sac contents are inspected it is important that they are subsequently identified and retrieved so that a loop of non-viable gut is not inadvertently left in the abdomen. Retrieval of reduced sac contents can be an awkward business via the internal ring and occasionally a formal laparotomy may be required to inspect matters properly. It is for these reasons that great care should be taken to secure the sac contents for inspection as soon as possible during the procedure. If the hernial sac contains omentum only, then any tissue which is necrotic or of doubtful viability should be excised, ensuring meticulous hemostasis in the process. If, on the other hand, bowel is involved, then any areas of questionable viability should be wrapped in a warm moist gauze pack and left for a few minutes to recover. If there is a small patch of necrosis that does not involve the whole circumference of the bowel then this can sometimes be dealt with by invagination rather than by resorting to resection. In this situation the injured bowel wall is invaginated by a seromuscular suture, taking bites on the viable bowel on either side of the defective area of gut. Rogers Occasionally, particularly if a bowel resection has been necessary, edema of the herniated gut makes its replacement in the abdomen difficult. Maneuvers such as putting the patient into a marked Trendelenburg position and gently compres sing the eviscerated gut, covered by a large moist gauze swab, will almost invariably allow the bowel to be replaced in the abdomen. It is possible to minimize the chances of this difficulty arising if care is taken during any bowel resection not to have any more gut outside the abdomen than is absolutely necessary. Though this incision you enter the peritoneal cavity and reduce the hernial content simply by pulling on it from within. The question of the type of hernia repair to be employed is a matter for the individual surgeon, with one proviso. In these days of tension-free hernia repair, it seems imprudent to place large amounts of mesh in the groin if necrotic gut has had to be resected. In this situation some other type of repair seems advisable to obviate the misery of infected mesh. Femoral Hernia You can approach the acute femoral hernia from below the inguinal canal, from above, or through it. You find the hernial sac and open it, making sure to grasp its contents for proper inspection. Strangulated omentum may be excised, viable bowel is reduced back into the peritoneal cavity through the femoral ring. When the ring is tight, and usually it is, you can stretch it with your small finger, inserted medially to the femoral vein. You can resect non-viable small bowel through this approach and even anastomose its ends, but pushing the sutured or stapled anastomosis back into the abdomen is like trying to squeeze a tomato into a cocktail glass. Therefore, when bowel has to be resected, it is advisable to do it through a small right lower quadrant muscle splitting laparotomy (as for appendectomy). This involves an approach to the extra peritoneal space along the lateral border of the lower part of rectus abdominis. The skin incision may be vertical, in line with the border of rectus, or oblique/horizontal. A vertical skin incision has the merit of allowing extension to a point below the 22 Acute Abdominal Wall Hernias 195 inguinal ligament and this may be helpful in reducing stubborn hernias, allowing traction from above and compression from below. Once the space behind the rectus muscle has been accessed the hernia can usually be freed from behind the inguinal ligament. The peritoneum can be opened as widely as necessary to permit inspection of the contents of the hernial sac and to carry out intestinal resection if necessary. All above approaches are reasonable provided the contents of the hernial sac are examined and dealt with appropriately. As with inguinal hernias the implanta tion of large amounts of mesh should be avoided in patients who have contamina tion of the operative field with intestinal contents. With this caveat the choice of repair is not different from what you would do in the elective situation. Incisional Hernias Incisional hernias are common but most are asymptomatic except for the unsightly bulge and discomfort they sometimes produce. When bowel has been incarcerated there may be associated symptoms of small bowel obstruction (Chap. It is important to distinguish between intestinal obstruction caused by the incisional hernia or simply associated with it. It is for this reason that the contents of any hernia asso ciated with obstruction must be examined carefully at operation to ensure that the hernia truly is the cause of the obstruction. We recall a case of obstruction that was addressed by reducing and repairing a tense femoral hernia, only for the obturator hernia, which was the true cause of the obstruction, to be discovered at laparotomy many days later when the patient failed to recover from the first operation. This is also true with other types of abdominal wall hernias, such as paraumbilical or epigastric ones. They only contain extraperitoneal fat from the falciform ligament, and for this reason need not be repaired routinely in the absence of symptoms. After the contents of the hernia have been dealt with identify the fascial margins of the defect. Bear in mind also that leaving non-absorbable mesh in contact with the gut leads to difficulties and disasters later. Isolated ischemia of the colon, which is much less common, will be discussed separately under the heading of ischemic colitis in Chap.

Geriatric Use: Elderly patients may be at greater risk for complications of constipation. However, individual oral doses of 16 mg have been administered in clinical studies without significant adverse events (usual dose is 2mg). These changes are reflective of the serious gastrointestinal adverse events, some fatal, that have been reported with its use. Once a physician is enrolled in the Prescribing Program by confirming qualifications, acknowledging described responsibilities, and submitting the Physician Attestation Form, they will receive a prescribing kit from GlaxoSmithKline. At this point, both the physician and patient sign the Agreement Form and provide the patient with a copy of the form. In order for the patient to fill the prescription and any refills, the Prescribing Program Sticker must be on the prescription. Once the prescription is filled, the patient will be given a Retail Pack containing the Medication guide, Package Insert, Medicine, and the Follow-up Survey. At this time, the pharmacist will once again encourage the patient to enroll in the follow-up survey. Tegaserod-treated patients reported greater relief from symptoms and a greater increase in number of stools than placebo-treated patients, with the largest difference during the first four weeks. Fasting oral bioavailability is approximately 10% and administration with food reduces bioavailability by >40%. The medication is 98% protein bound and highly lipophilic, with extensive tissue distribution. Monitoring: Relief of constipation should be demonstrated, with diarrhea the most common side effect. During episodes of diarrhea lasting >2 days, periodically monitor electrolyte levels (sodium, potassium, chloride, bicarbonate). Contraindications: Tegaserod is contraindicated in patients hypersensitive to the drug and in those with a history of bowel obstruction, gallbladder disease, and severe renal impairment, moderate to severe hepatic impairment, abdominal adhesion, and suspected sphincter of Oddi dysfunction. Caution should be exercised in patients with diarrhea and in pregnant and breast-feeding patients. Background Miscarriage and ectopic pregnancy can cause significant maternal morbidity and 3-6 mortality. Vaginal bleeding that does not lead to miscarriage has been linked to pre-term birth, stillbirth and low 4, 6 4 birth weight. Ectopic pregnancy, the most dangerous cause of vaginal bleeding; is increasing in incidence due to earlier diagnosis along with an increased use of 3 assisted conception. Gestational trophoblastic disease or molar pregnancy is rare occurring between 1 in 1000 pregnancies but is important to consider in 5 assessment. Assessment It is crucial to first assess for haemodynamic stability by recording vital signs and reassess the patient regularly. Symptoms such as unexplained shock, signs of syncope, shoulder pain and tenesmus may suggest a rupture requiring emergency treatment. Following assessment If early pregnancy bleeding or pain: Refer to the following guideline sections within this document: Bleeding (Early Pregnancy) Algorithm Bleeding (Vaginal) and a Viable Intrauterine Pregnancy. N Dysfunctional Uterine Bleeding Y Refer accordingly Is intrauterine gestation Y sac seen on N Ultrasound Threatened miscarriage is the most common complication of early pregnancy 8 occurring in 20% of women before 20 weeks gestation. An increased risk of antepartum haemorrhage, pre-labour rupture of membranes, preterm delivery and intrauterine growth restriction has been 9 documented. Transvaginal scanning has a positive predictive value of 98% in confirming diagnosis of complete miscarriage and should be used in assessment. Fetal bradycardia was a sign present in 1 in 3 pregnancies that were subsequently lost, whilst 7% of pregnancies that continued 12 had bradycardia found on ultrasound. Non-sensitised rhesus negative women should receive anti-D immunoglobulin 8 for threatened miscarriages. Advise the woman that if vaginal bleeding gets worse or persists beyond 14 days, she should return for further assessment. By 5 14, 15 weeks + 2 days the sac should be visualised, and should be 2-5 mm in diameter. It is imperative to have a high specific test with zero false 17 positive rate as diagnosis of fetal demise results in evacuation of the uterus. Disproportionately small or non-visible embryo within an enlarged amnion is a good 14 marker for a failed pregnancy. Theoretically cardiac activity should be evident when embryo is over 2mm, but in 5-10% of cases where this has been documented 19 pregnancy outcome was normal. Early normal pregnancies always show a gestational sac but no detectable embryo during a brief but 14 finite stage of early development. Once a gestational sac has been documented subsequent loss of viability remain around 11%, there is no difference between 19 gestational sac diameter when compared with pregnancy outcome. When it first appears on ultrasonic imaging, the gestational sac is surrounded by a thickened decidua.

Ideally this should be performed or supervised by an experienced Gynaecologist, under ultrasound guidance, to ensure the uterine cavity is empty at completion and to minimise the risk of perforation. Patients should be counselled regarding their diagnosis, follow up requirements, and the implications for their future pregnancies. Pregnancy should be avoided until after the completion of the surveillance period. Obstetrics & Gynaecology Page 12 of 60 Pregnancy: First trimester complications Oestrogen and/or progestogen contraceptives. The types of trophoblast disease range from the usually benign partial and complete molar pregnancy through to invasive mole, 21, 24 malignant choriocarcinoma and placental site trophoblast tumours. Historically the relative incidence of partial and complete molar pregnancies has 24 been reported as approximately 3:1000 and 1: 1000, respectively. Macroscopically partial moles may resemble the normal products of conception as they contain embryonic or fetal material such as fetal red blood cells. Complete mole Complete moles are diploid and androgenic in origin with no evidence of fetal tissue. The genetic material is entirely male in origin and results from the fertilisation of an empty ovum lacking maternal genes. Women may also present with a wide variety of symptoms from distant metastases to the 29 lungs, liver and central nervous system. Invasive mole (Persistent Gestational Trophoblastic Disease) Invasive moles usually arise from a complete mole and is characterised by the invasion of the myometrium, which can lead to perforation of the uterus. Microscopically, invasive moles have a similar benign histological appearance as complete moles but is characterised by the ability to invade in to the myometrium and the local structures if left untreated. The average interval between the pregnancy event and presentation of disease is 3. Other presentations 31 may include amenorrhea, hyperprolactinemia or nephrotic syndrome. Consider evacuation under ultrasound guidance due to increased perforation risk with molar pregnancies. Send all products of conception for histology examination and consider cytogenetics 5. However, there is an increased risk of perforation and excessive bleeding with repeat D&C. There is minimal role for repeat pelvic ultrasound in these cases and thus should not be routinely ordered. Provide information of discharge, the follow-up management and include management if the woman presents with a future pregnancy. Following chemotherapy for an invasive molar pregnancy, woman may be at increased risk of miscarriage or stillbirth if they fall pregnant within 12 months of completing multi-agent chemotherapy. Negative laparoscopy Rarer forms of ectopic pregnancy such as interstitial/corneal implantations can be missed at laparoscopy. The woman must be contacted and if pain is present, prompt medical review should occur. The woman should be warned of the risks of on-going ectopic pregnancy and the need for closely monitored follow-up. Safety and efficacy of antiemetic medications should be discussed with women if symptoms are severe. Women should be advised about appropriate foods and fluids to prevent dehydration and minimise aggravation of symptoms. However, there is currently insufficient high quality evidence to support a particular choice of complementary therapy. Discontinuing iron containing multivitamins and supplements (where appropriate) may improve hyperemesis symptoms. Higher levels of hcg seen with molar or multiple pregnancies are associated with more severe symptoms. Obtain a specific history of nausea and vomiting pattern and dietary history to ascertain state of nutrition and recent intake. It is important to reassure women that 40 symptoms will subside by 20 weeks in 90% of cases. Second-line therapy If nausea and vomiting persists then a second sedating antihistamine should be 52 added. It should only be used with protracted vomiting when other therapies have failed to improve symptoms or there has been recurrent hospitalisation. Note: Large cohort studies on the safety of Ondansetron in pregnancy have provided conflicting results with some showing as increase in oral clefts. Ondansetron should be considered as a non-first line agent for the treatment of nausea and vomiting in pregnancy. Glucose levels should be monitored for hyperglycemia which has adverse effects on the fetus. Note: Most studies describing the use of maternal corticosteroids have not reported 40-43 an increased risk of major malformations. Early reports have suggested an 40, 44 association between corticosteroid use and increased risk of cleft lip and palate. Enteral feeding Consider enteral feeding in extreme cases of intractable vomiting that do not 56 respond to any of the above interventions. Iron absorption increases in the second trimester of pregnancy so unless the woman is anaemic, iron supplements or supplements containing iron can be stopped or 59 swapped for a lower does in the first trimester. Where there is intractable vomiting or reflux, investigation should be considered for H. Persistent nausea is debilitating and can lead to feelings of isolation from partners, friends and family. The inability to complete simple daily tasks and look after children may lead to strained relationships at home and being unable to attend work may also lead to further tension and financial stress. Women may also feel guilty that they are unable to eat healthily and that taking medications may harm their baby. It is important for medical practitioners to be empathetic, offer reassurance and explain the condition to the patient and partner and explain that most anti-emetics are safe during pregnancy.
