Long-term patients who receive little nutrition from other sources are at risk of micronutrient deficiencies. Endoscopy in particular must be undertaken with great care as there is a documented risk of iatrogenic perforation of the diverticulum. The palatopharyngeal folds on either side approximate each other to form a sagittal slit allowing properly masticated food to pass with ease and yet impeding the passage of large objects. It does, however, allow the entire length of the upper gastrointestinal tract to be visualized and exclude gross organic pathology, reassuring both the patient and the surgeon. Breast pain (mastalgia) Breast discomfort or pain at some time is reported by two-thirds of women; mastalgia can be defined as breast pain of sufficient severity for a woman to seek medical advice. True congenital shortening of the oesophagus in infancy and childhood is very rare. The presence of copious purulent sputum containing leucocytes and intracellular bacteria on Gram staining is enough to make a diagnosis pending the results of culture. The indications include: pelvic and lower limb surgery can be performed under a spinal block. In such patients presenting with good prognosis tumours, bilateral mastectomy should be discussed with the patient by her surgeon. Eggs passed in faeces of dog and fox Eggs swallowed by sheep, cattle, wild rodents, etc. The hospital management is responsible for ensuring that the written procedures are updated and made available to all staff (medical and nursing) who may have to administer transfusions. In diffuse hepatic steatosis a more diffuse generalized hyperechogenicity is typically observed. Barium enema or colonoscopy may be indicated to exclude a colonic source of portal pyaemia. Wound infection is the most significant independent factor for incisional ventral hernia. Smoking cessation may reduce the risk of hospital-acquired infection and thus should be strongly encouraged preoperatively. Graft-versus-host disease this is a rare but usually fatal complication that occurs mainly in immunodeficient patients. Treatment of cardiogenic shock associated with blunt cardiac injury should include replacement of intravascular volume, inotropic agents and occasionally placement of an intraaortic balloon pump. In some patients, an exchange transfusion has to be carried out to avoid severe congestive failure. The genital type affects the vagina or vulva of middleaged women and may cause dyspareunia. This is recognized to occur in conditions that are associated with fat or bile acid malabsorption such as inflammatory bowel disease, pancreatic insufficiency, bowel resection and blind loop syndrome as well as jejunoileal and Roux-en-Y bypass. Epinephrine is ineffective in angio-oedema caused by C1 esterase inhibitor deficiency. However, it is important to be aware that structures within the chest may be damaged by penetrating wounds outside the boundaries of the thorax. Portal hypertensive gastropathy this condition can cause acute or chronic repeated gastrointestinal blood loss. Phylloides tumours progressively increase in size, and range between a benign appearance and more sarcoma-like appearance with an increasing number of mitotic figures on histology. To avoid precipitation of calcium salts intravenous calcium and bicarbonate should never be administered via the same vascular access. At high levels it can also be associated with hypotension, organ failure and death. The parasitized red blood cells now rupture, releasing merozoites, the majority of which re-enter erythrocytes to reinitiate erythrocytic schizogony.

Once the decision to operate has been made, antibiotics should be given prophylactically. Disturbance of this fine balance between mesothelial repair and fibrinolysis by ischaemia and other factors is thought to be responsible for adhesion formation after abdominal surgery. The dermis itself is composed of fibroelastic tissue, which supports the epidermis and its appendages. A number of non-platinum agents are also active including gefitinib and the newer antifolates which target or restore deficient p53. Because of this, alternatives to open surgical repair are very attractive, and there is growing experience with covered stents for treatment of subclavian artery injuries. In the more usual condition, an exanthematous rash develops over a dermatome supplied by a specific dorsal nerve root or extramedullary nerve ganglion. Arteriography in this area is important in defining the site and extent of all the injuries. Adenomatous polyposis coli gene mutation alters proliferation through its beta-catenin-regulatory function in aggressive fibromatosis (desmoid tumor). Although viral loads do invariably correlate with the disease severity or poor prognosis, they are useful in the identification of patients who are likely to respond to antiviral therapy. Shock, acidosis, suprarenal injury and lack of retroperitoneal tamponade are independently associated with mortality. However, palliative surgery is an extremely uncommon procedure in Western centres because of the advances of pyloric stents and oncological management. Only 5% of women with breast cancer have internal mammary node metastases, usually from medially placed cancers, but 90% of these women also have axillary metastases, so most surgeons do not perform internal mammary node biopsy. Treatment of venous malformations must be planned by delineating the extent of the abnormal vessels. Copper studies (serum copper, serum caeruloplasmin and urinary copper levels) should Box 24. It differentiates viable from non-viable tumour, which may be increasingly important for in situ ablation of tumours. It is thought that limiting fat intake to 2 g/kg body weight per day may help to avoid this effect. It is more common in males (male to female ratio, 2:1), affects elderly patients over 60 years and is rare in dark-skinned individuals. On the other hand, the arterioles have a muscular wall that is thick by comparison with their lumen and they make the largest contribution to afterload, which is why they are called the resistance vessels of the body. The tube has an inflatable balloon near its tip, which facilitates passage down the small intestine into the caecum. If the unit of whole blood has been left out at room temperature for more than 30 minutes prior to commencement of infusion, the unit should be discarded. Ketamine this drug is gaining in popularity, especially in emergency and field anaesthesia. Histologically, the tumour cells often excite a localized lymphocytic response that appears to induce regression of parts of the tumour. The injury appears to be due to hypersensitivity, and the impaired liver function is associated with pyrexia, skin rashes and eosinophilia. Rupture of an amoebic abscess into the lung and bronchus can usually be treated successfully by antibiotics and postural drainage. In addition to surface attachment, the organism can invade the gastric epithelial cells. Most tumours measure <2 cm but those smaller than 1 cm may be missed, particularly in thin patients with little perinephric fat. A nasogastric tube should be inserted during initial evaluation, and aspiration of blood may point to a gastric injury. The history should also include information from the prehospital providers regarding the mechanism of injury, which can help the physician Soft-tissue injuries of the neck 289 assessed for passive and active range of motion, long bones should be assessed for instability, the limbs should be examined for external signs of trauma or violation of the joints, and a sensory examination of all dermatomes should be performed to assess for peripheral nerve injury. The transversalis fascia consists of two layers: anterior, adherent to the rectus muscle, and posterior, which faces the parietal peritoneum (space of Borgos). Excision of the fistula through a circumareolar incision including the duct up to the back of the nipple under antibiotic cover is the treatment of choice, rather than laying open the length of the fistula with the resultant scarring and deformity.

In both conditions gastric necrosis supervenes when the intragastric pressure exceeds the gastric venous pressure. Because the pre- and intraoperative diagnosis of lymph node metastasis may need revision, D2 lymphadenectomy should be performed whenever nodal involvement is suspected. The initial phase appears to be largely mediated by an axon reflex, whereas the secondary prolonged hyperaemic phase is caused predominantly by the endothelial release of nitric oxide. Intra-abdominal desmoid tumours remain asymptomatic until they reach a large size and then present with evidence of compression of adjacent organs: intestinal tract, ureter or vascular tree. Conservation surgery Wide local excision is excision of a tumour with a margin of clearance of both invasive and in situ disease. Once the fractures have been stabilized the temporary intravascular shunts can be removed and definitive vascular repair performed in the stabilized limb. In patients with positive fluid balance, large fluid intake and inadequate urine output, steps should be taken to limit fluid intake while avoiding intravascular volume depletion. Initial evaluation the propensity of respiratory compromise in patients with vascular or tracheal injuries makes the early establishment of a secure airway a priority. Postoperative complications after antireflux surgery include: Surgical treatment There is evidence to suggest that symptoms of heartburn, reflux and bloating are improved after surgery compared with medical therapy. Blunt trauma is the cause of most injuries, with pedestrian and motor vehicle accidents accounting for the majority. Thus, orbital tumours cause proptosis and dysconjugate gaze; vaginal rhabdomyosarcoma presents as a protruding polypoid mass; it is a painless testicular/paratesticular mass in young boys; and is an initially painless enlarging mass of the extremities in adolescents of either sex, etc. Annular pancreas Many instances of annular pancreas present in adult life with symptoms of pyloric stenosis and there is an established association of this congenital anomaly with Down syndrome and other congenital abnormalities. The excessive administration of amino acids has been associated with cholestasis in paediatric practice and possible alterations in bone metabolism. The most common clinically significant electrical disorders are tachyarrhythmias, of which atrial fibrillation is the most likely. Stage 3: unresectable unilateral tumour infiltrating across the midline, regional lymph node involvement, or both. The melanocytes gradually become incorporated into the dermis by fibroblast migration. Several clinical studies in trauma patients have indicated potential benefits, although the reported data are not conclusive. The results of the randomized study from Korea in which patients were given either capecitabine and cisplatin chemotherapy or capecitabine and cisplatin chemoradiotherapy after D2 resection are awaited with great interest. The solid-state strain gauge microtransducers can be connected directly to the readout system. The histology shows large polygonal cells in a dense fibrous stroma that forms bands or lamellar structures. Antimicrobial synergy occurs, for example, when an aminoglycoside is combined with penicillin for treatment of certain staphylococcal or enterococcal infections, and with ticarcillin for enhanced activity against Pseudomonas spp. These operations should be performed under prophylactic antibiotic cover, and, if for any reason the bowel is injured during the operation or resection of an intestinal segment is performed, a full 5 day antibiotic course to cover Gram-negative organisms (anaerobes and aerobes) is necessary. Malabsorption of bile salts and/ or fatty acids consequent on the intestinal vagal denervation has been implicated but never confirmed. Brachytherapy might be a suitable alternative to self-expanding metallic stents in providing a survival advantage and possibly a better quality of life. Best eye-opening response There are four possible best eye-opening responses in any patient: 1, no eye opening to any stimulus; 2, eye opening to painful stimuli; 3, eye opening to verbal stimuli; and 4, eye opening spontaneously Table 15. Several prospective randomized trials on adjuvant chemotherapy have demonstrated decreased local recurrence rates in patients who received adjuvant regimens. Previous studies have shown that ligation of the common or external iliac vein is well tolerated with few adverse sequelae.

The incidence of blunt trauma is increasing owing to the increasing rate of automobile and motorcycle accidents. The metabolic activity of thyroid hormone is determined by the amount of free T3 and free T4. A high intake of carbohydrate is essential and amino acid solutions containing aromatic amino acids should be used sparingly as these may precipitate encephalopathy in susceptible patients. In essence, the liver should be regarded as a paired organ (right and left livers) fused along a line extending from the middle of the gallbladder fossa anteriorly to the left edge of the suprahepatic inferior vena cava posteriorly. This has been attributed to intrahepatic arterioportal anastomoses, hyperdynamic circulation and the accumulation of vasoactive humoral factors which alter the resistance to flow. Aortoenteric fistula this usually complicates aortic replacement with prosthetic grafts but may arise spontaneously. This behaviour facilitates both the detection of focal liver lesions which do not contain Kupffer cells. However, they can include reflux oesophagitis, ulcerative oesophagitis, formation of strictures and webs. Finally, it is equally essential to recognize when the interventional approach will not succeed and surgery is the only treatment. Prostheses External breast prostheses are the most common method of restoring breast symmetry following surgery, and a wide variety of shapes and sizes are available. Malnutrition leads to anergy, with the loss of cutaneous responses to antigens traditionally determined by the Mantoux response. Poor distal back bleeding, stump pressures in the carotid artery <60 mmHg or electroencephalographic changes during intraoperative monitoring suggest the need for shunt placement to maintain cerebral perfusion while repairing the innominate artery. Central and mixed venous oxygen saturation Central venous oxygen saturation can be measured from blood taken from the superior vena cava. Complications Endoscopic treatment is faster and less invasive than open surgical therapy with fewer reported complications. It is most commonly seen in white-skinned individuals and presents clinically as a red scaly patch on the exposed skin of the elderly. Episodes of infection in the critically ill have been directly related to enteral feeds, and there is the risk of infection with specific intestinal pathogens such as Salmonella spp. The brood capsules undergo localized proliferation and invagination of their walls to form scolices (tapeworm heads). Primary gastrinomas may very rarely occur in other sites: body of the stomach, jejunum, peripancreatic lymph nodes, splenic hilum, root of the mesentery, omentum, liver, gallbladder, common bile duct, and the ovary. As a consequence of these processes, signs of local inflammation (rubor, calor, dolor) occur. Stopping smoking, regular exercise and adequate nutrition should be routine advice for patients undergoing oesophageal surgery. Some patients present with dyspeptic symptoms and are found to be anaemic on examination. Whenever possible, the immune depression is reversed at least partially by dose reduction of any immunosuppressive drug. Regurgitation this symptom results from regurgitation of gastric or oesophageal fluid into the throat accompanied by a sour taste in the mouth. Herniation occurs in regions of the oesophagus which are weakened or have a low resistance. Tumours arising from the smooth muscle of the muscularis mucosae can pedunculate and protrude into the oesophageal lumen. It is used to demonstrate contrast extravasation, tumour vascularity and/or early draining vein (indicative of angiodysplasia).

One of the most important aetiological factors associated with both intestinal and diffuse gastric cancer is H. The strap muscles on either side are separated by dividing the deep fascia in the midline and retracted laterally. The majority of lacerations to the lung involve low-pressure vessels of the pulmonary circulation and bleeding can be expected to stop after placement of the chest tube and reexpansion of the lung. Shoemaker and colleagues demonstrated that patients incurring a significant oxygen debt during surgery are at high risk of postoperative complications. The first two have the disadvantage that they can both cause a reflex tachycardia so that they may need to be combined with a cardioselective beta-blocker. The total epithelial thickness is less than normal and is composed entirely of basal cells. One major limitation here is that all inotropic drugs can cause arrhythmias, so that they tend to be reserved for acutely ill Cardiac pharmacotherapy 179 patients and to be used for as short a time period as the clinical situation permits. Postsplenectomy patients are at most risk for infection from encapsulated organisms, such as Streptococcus pneumoniae, Haemophilus influenzae and Neisseria meningitidis. Acute disease- or injury-related malnutrition: when inflammation is acute and of severe degree; examples include major infection, burns, trauma or closed head injury. Nevertheless, even with more extensive surgery, radiotherapy significantly reduces the local recurrence rate. The European Society for Parenteral and Enteral Nutrition recommends a daily protein intake of 1. The segment has a spontaneous tendency to relax periodically at times unrelated to swallowing. Occasionally, large tumours may show evidence of sarcomatous change and have a poor prognosis. Treatment of compartment syndrome should not be delayed, as irreversible myonecrosis with resultant contracture will occur within 12 hours. Injuries to the axillary and brachial arteries require urgent exploration and can usually be managed by thrombectomy and primary repair with or without a vein patch. With this length of abdominal oesophagus cleared, it is quite easy to inspect the region of the fundus and thus ensure against missing nerve fibres (of Grassi) to this region. The age distribution at the time of diagnosis is: 40% of patients are <1 year, 35% are aged between 1 and 2 years and 25% are >2 years when diagnosed. In other instances, the primary infection occurs in the ileocaecal region (20%) or lungs (10%). Tumours are usually homogeneous with decreased attenuation both before and after contrast enhancement because of their low lipid content. Both techniques are only applicable to clean operative sites without bacterial, bowel or tumour cell contamination. In addition, infants may acquire extragenital infection during delivery from a mother with acute syphilis. Eating pattern There is a decreased risk of oesophageal squamous cell carcinoma but not oesophageal adenocarcinoma with higher intake of both fruit and vegetables. This box is bordered by the clavicles and costal margins superiorly and inferiorly, and bilaterally at the mid-clavicular line. After initial promising results, other authors were not able to confirm this hypothesis and the concept has been abandoned these days. The chemical injury is accentuated by a defective clearing of the refluxate by the oesophagus consequent on an impaired motility. Effective communication between clinician and radiologist is essential in order to maximize the diagnostic utility of imaging tests for the patient. As with the phosphodiesterase inhibitors, a vasopressor such as norepinephrine often needs to be infused as well to offset its vasodilatory effect. They enter the transverse foramen at the level of C6, and superior to this point they are contained within the bony vertebral canal before entering the base of the skull through the foramen magnum. The prognosis of malignant phase hypertension was extremely poor (median survival 6 months) in the 1950s before antihypertensive therapy was available. The possible benefits of prophylactic intervention should be discussed with a nephrologist. The important practical issue in the management of patients with dyspepsia relates to which patients should be investigated by upper gastrointestinal endoscopy before treatment. Mastectomy may be complicated postoperatively by haematoma or seroma formation beneath the skin flaps (and hence most surgeons leave in a vacuum drain beneath the skin flaps), wound infection (which should complicate <2% of operations) or, rarely, flap necrosis.

It appears as a flat, pigmented lesion with an irregular edge and non-homogeneous pigmentation. Additionally, preservation of as much intact airway as possible is important if there is a tracheal injury. Lee and colleagues studied over 4000 patients at a tertiary centre undergoing elective non-cardiac surgery. Patients were randomized to four cycles of 5-fluorouracil and cisplatin with concurrent 50 Gy total dose radiotherapy compared with 64 Gy total dose radiotherapy alone. As the right heart fails there is decreased left heart preload, resulting in decreased cardiac output. This physical consideration accounts for the unsatisfactory results of surgical repair irrespective of its nature. In these cases treatment should focus on correction of the underlying condition, such as augmentation of nutrition in hypoalbuminaemia or treatment of cardiac failure/fluid overload. It acts as an N-methyl-d-aspartic acid antagonist and can cause profound analgesia, anaesthesia and amnesia. Computed tomographic angiography as an aid to clinical decision making in selective management of penetrating injuries to the neck: a reduction in the need for operative exploration. Although the precise conditions that result in the development of this endogenous infection are not known, the disease often follows trauma such as extraction of a carious tooth. The venous drainage of the thyroid is via the superior and middle thyroid veins, which drain into the internal jugular and the inferior thyroid veins, which drain into the brachiocephalic vein. It is a disease of children and adolescents, with the vast majority of tumours (90%) occurring below 15 years, the disease being very rare in adults. Indocyanine green clearance this is presently considered to be the best test of hepatic functional reserve. Comparison of the concurrent with the sequential arms in N9831 revealed an improvement in disease-free survival favouring the concurrent arm (hazard ratio 0. Sodium restriction [2000 mg/day (88 mmol/day)] is associated with reduced diuretic requirements, more rapid resolution of ascites and shorter hospital stay. High-dose chemotherapy treatment is more active but is accompanied by increased toxicity; for this reason, it is administered for a shorter duration, usually 6 months in patients unresponsive to other therapies or with very rapidly growing symptomatic tumours. Patients are positioned as for an open posterior approach and a balloon is inserted and inflated in the retroperitoneal space below the twelfth rib. Ultrasound is also useful in the preoperative assessment of the axilla in breast cancer patients. Asbestos-related mesotheliomas occur most commonly in the pleura, but instances of peritoneal mesotheliomas due to asbestos exposure are well documented and asbestos bodies (mainly amosite) have been documented in the peritoneal cavity, the most common sites being the mesentery and omentum, usually in patients with heavy-fibre burdens in lung tissue. Shock can be categorized by the underlying pathophysiological mechanism: administering fluid boluses carefully, particularly when right ventricular impairment is present. Malaria develops up to a year after visiting an endemic area, although it usually develops within 3 months of the visit. Once the patient is considered normovolaemic, care should be taken to avoid fluid overload and a maintenance regimen started, with careful fluid balance charts to take into account renal and insensible fluid losses, aimed at achieving a positive balance not exceeding 500 mL/day. Examples of such grades include: Obesity Obese patients have an increased risk of respiratory complications, deep vein thrombosis, wound infection and wound dehiscence. The condition usually complicates a pre-existing gastric lesion and is more commonly encountered in elderly and alcoholic patients. Cases caused by benign carcinoids may be difficult to diagnose as the onset of Cushing syndrome may be insidious over several years. By definition, however, adrenal insufficiency following bilateral adrenalectomy is not Addison disease. Blood components Whole blood and blood components are prepared in regional transfusion centres from individual donations or pools of a small number of donations. The former are usually <135 beats/ min whereas the latter are usually >145 beats/min. Peripheral non-lactating breast abscess may be associated with diabetes, steroid therapy or rheumatoid arthritis.

It is widely available and indicates the local stage and the presence of metastasis. Chronic obstructive airways disease is followed by a higher incidence of postoperative pulmonary complications than is restrictive airway disease. On the left side, in obese patients identification of the gland can sometimes prove very difficult. It is particularly useful in the investigation of patients with jaundice, chronic liver disease, ascites of unknown origin and in the diagnosis and staging of both primary and secondary hepatic tumours. As described above, sepsis often presents clinically with hypoperfusion of organs. The nutritional blood supply to the stomach (with the exception of the lesser curvature) is derived from this plexus. Immediate histological examination of the sentinel node, if negative, will prevent the need for further axillary surgery. Inferior mesenteric artery/inferior mesenteric vein injuries are approached directly and, if amenable, primarily repaired or ligated. The lesions are found on the penis and perianal region in the male, and labia, clitoris, vagina, cervix, perineum and perianal region in the female. This is of significant concern as the number of resected lymph nodes has been shown to be a determinant factor for survival in oesophageal cancer. Granulomatous gastritis Granulomatous gastritis may be infectious or non-infectious. Apart from overeating, other predisposing factors include neurological disorders, tumours and gastrointestinal obstruction. It presents with an enlarging, painless soft-tissue mass most commonly in the muscle compartment of the thigh. Venous malformations Venous malformations are also known as cavernous haemangiomas. Chronic adrenal insufficiency will require maintenance therapy with hydrocortisone, usually 20 mg in the morning and 10 mg in the evening. Zone 3 injuries may involve the petrous or cavernous portions of the internal carotid artery, the vertebral artery or deep branches of the external carotid artery. The difference in ulcer recurrence rates may be related to the extent of gastric resection since more stomach is likely to be retained in Billroth I operations to achieve a gastroduodenal anastomosis without tension. The insulin test After complete denervation of the parietal cell mass, acid output is reduced by 50% or more. Percutaneous catheter drainage is monitored by serial ultrasound examination to assess the degree of resolution. Laboratory investigations reveal leucocytosis, raised inflammatory markers but only a mild elevation of the transaminases. Both the Taylor and the Hill operations can easily be performed laparoscopically and there are several such reports on the laparoscopic Taylor operation. It binds to troponin C, increasing myocardial calcium sensitivity, and has a positive inotropic effect. This approach permits thorough exploration of the abdomen, irrigation and aspiration of the thick mucinous material and the instillation of mucolytic agents (5% dextrose solution). Certainly, elderly patients undergoing major planned surgery for colorectal cancer are more likely to die following surgery than younger patients with a similar comorbidity burden. Therapy has one of two different aims, either viral eradication with defined therapy or viral suppressive therapy long term to Parenchymal disorders of the liver A full description of all liver disease is beyond the scope of this chapter. Desmoid tumor: prognostic factors and outcome after surgery, radiation therapy, or combined surgery and radiation therapy. Therefore, management of patients with breast cancer may involve surgery, radiotherapy, systemic therapy (hormonal and/or chemotherapy) or a combination of these. Because of this, the operating theatre has several advantages over the emergency department for airway management in patients with neck injury.

Stage 4: any primary tumour with dissemination to distant lymph nodes, bone, bone marrow, liver, skin and/or other organs (except as defined for stage 4S). This is divided into two sections: the physiological score, to be scored at the time of surgery, and the operative severity score. Metastatic spread to local and regional lymph nodes is consequently rare, obviating the need for extensive anatomic and nodal resection as performed in cases of gastric adenocarcinoma. Measuring liver volume Advances in imaging and software have allowed the development of in vivo imaging of the liver. Complete failure of descent may result in a lingual thyroid, at the back of the tongue. During these scans the patient is moved through the scanner gantry while both the X-ray source and X-ray detectors rotate around the patient. A superficial haemangioma or strawberry naevus is bright red and raised with a characteristic appearance. However, the main feature of the disease is severe lymphoedema, most frequently in the lower extremities, but it may involve the arms, breasts, scrotum, penis and vulva. Zone 1 adjacent to the portal triad is the best vascularized and least susceptible to injury. The history should be directed at detection of pre-existing conditions or medications that may alter management of life-threatening injuries. Marked crepitance is indicative of subcutaneous emphysema, which can result from major bronchial injury, pulmonary parenchymal injury or oesophageal injury. The administration of neoadjuvant therapy has no worse outcome than the administration of adjuvant therapy; however, several benefits can be derived from preoperative systemic therapy. Additionally, gastric emptying is influenced by changes in the tone of the gastric fundus. Enteral nutrition should be employed wherever possible; it is cheaper, safer and more physiological than parenteral feeding. As neither preparation affects either the bleeding time or coagulation time (except by dilution), they are perfectly safe for large-volume colloid replacement. The correct treatment here is either intravenous diuretic therapy or venodilator therapy such as nitrates. The usual age at onset is between 50 and 70 years, the disease presenting with one or more firm asymptomatic red, purple or brown patches, plaques or nodular skin lesions. The psychosocial effects of breast reconstruction, and the relative merits of immediate and delayed surgery, have not been adequately studied. Cushing syndrome the physiological and clinical features of Cushing syndrome are due to excessive levels of circulating glucocorticoids. Functional or segmental anatomy of the liver the segmental anatomy of the liver on which modern hepatic surgery is based comes from the anatomical dissections performed by Rex (1888) and Cantlie (1898) more than 100 years ago and subsequently elaborated by Goldsmith and Woodburne (1957), Couinaud (1957), Healy and Schroy (1953) and Elias and Petty (1952). The presence of respiratory muscle weakness increases the risk of postoperative hypoventilation; pneumonia, weak cough and weak upper airway reflexes increase the risk of aspiration of gastric contents: Gastrointestinal considerations Anaesthesia obtunds the reflexes protecting the airway from foreign materials, including stomach contents. To date there is no evidence of any clear superiority of one procedure and there are no data on the efficacy of Seprafilm in reducing the obstructive episodes after adhesiolysis, but this seems a sensible addition to adhesiolysis especially as its use does not incur any adverse effects. Perioperative monitoring modalities offer realtime information on heart rate, urine output, oxygen saturation, stroke volume, arterial blood pressure, central venous oxygen saturation and cardiac output, thereby permitting manipulation. Perhaps due to their paucity and range, classification of the benign tumours is also extremely varied. The disease is not associated with hyperacidity and, indeed, hypoacidity is frequently encountered, particularly in patients with atrophic gastritis. Awareness of the condition is important as primary peritonitis is a rare condition in children, and thus it will be overlooked unless it is considered in the differential diagnosis of children presenting with an acute abdomen. Fentanyl may be given via any route, and morphine can be given orally or parenterally. Twenty per cent of gastrointestinal tract duplications occur in the thorax and some 60% of thoracic duplication cysts occur in the lower third of the oesophagus. In patients with iron-deficient anaemia, this should ideally be corrected by means of oral iron therapy if asymptomatic. The pylephlebitis induces a septic thrombosis of the portal vein and its branches, with multiple microabscess formation in the liver (honeycomb liver).
