Significant differences exist in the prevalence of most gastroenterological emergencies in tropical compared with temperate countries. Both ethnic and environmental (often clearly defined geographically) factors are relevant. The major oesophageal lesions which can present acutely in tropical countries are varices and carcinoma; bleeding and obstruction are important sequelae. Peptic ulcer disease (and its complications), often associated (not necessarily causally) with Helicobacter pylori infection, has marked geographical variations in incidence. Emergencies involving the small intestine are dominated by severe dehydration, and its sequelae, resulting from secretory diarrhoea, most notably cholera. However, enteritis necroticans ('pig bel' disease), paralytic ileus (sometimes caused by antiperistaltic agents) and obstruction (secondary to luminal helminths, volvulus and intussusception) are other important problems, especially in infants and children. Enteric fever is occasionally complicated by perforation and haemorrhage; the former (which is notoriously difficult to manage) is accompanied by significant mortality. Ileocaecal tuberculosis is a major cause of right iliac fossa pathology--sometimes associated with malabsorption; amoeboma is an important clinical differential diagnosis. The colon can be involved in invasive Entamoeba histolytica infection (which, like complicated enteric fever, is difficult to manage if the fulminant form, with perforation, ensues), shigellosis, volvulus and intussusception. Acute colonic dilatation occasionally follows Salmonella sp., Shigella sp., Campylobacter jejuni, Yersinia enterocolitica and rarely E. histolytica infections. Acute hepatocellular failure is a major cause of morbidity and mortality in the tropics and subtropics. It usually results from viral hepatitis (HBV, sometimes complicated by HDV, and HCV), but there is a long list of differential diagnoses. Hepatotoxicity resulting from herbs, chemotherapeutic agents or alcohol also occurs not infrequently. Chronic liver disease and its sequelae (often long-term results of viral hepatitis) are commonplace. Haematemesis and hepatocellular failure are usually very difficult to manage due to a lack of sophisticated support techniques in developing countries. Invasive hepatic amoebiasis usually responds well to medical management; however, spontaneous perforation can occur and the consequences of this are serious. Pyogenic liver abscess, although far less common than amoebic 'abscess', carries a bad prognosis whatever the method(s) of management. Hydatidosis and schistosomiasis also involve the liver, and helminthiases are important in the context of biliary tract disease. Gall stones are unusual in most tropical settings. Acute pancreatitis is overall unusual, but chronic calcific pancreatitis can present as an acute abdominal emergency.

Infusion manometry of the esophagus and the stomach after the permanent dynamic method of Winans [correction of Wynas] and Harris was carried out on 52 patients (30 women and 22 men) with hiatal hernia, volvulus of the stomach or peptic ulcer disease. Altogether 75 examinations were performed--35 preoperative and 40--postoperative. The mean preoperative pressure of the inferior esophageal sphincter was 9.1 (from 0 to 15) mmHg and the mean postoperative pressure was 18 (from 12 to 211 mmHg). The mean preoperative length of the inferior esophageal sphincter was 1.4 (from 0 to 4) cm and the mean postoperative length was 2.5 (from 1 to 6) cm. In 12 patients motor disturbances of the tubular esophagus were found: symmetric, hyperpersistaltic waves (Richter's nutcracker symptom)--in 3 patients, hypomotility--in 5 patients, diffuse esophageal spasm--in 4 patients. Esophageal manometry is a valuable noninvasive method for the functional diagnostic of the reflux disease and the motor esophageal disturbances as well as for the assessment of the postoperative function of the inferior esophageal sphincter.

A male patient was hospitalised for recurrent epigastric pain, abdominal fullness and vomiting. Peptic ulcer was suspected. Barium studies revealed the presence of chronic organo-axial volvulus of stomach. Anterior gastropexy associated with subdiaphragmatic displacement of transverse colon was done with satisfactory results.

A radiological diagnosis of gastric volvulus (GV) was made in 11 of 576 consecutive upper gastrointestinal series at the University of Benin Teaching Hospital, Nigeria, over a two-year period. The clinical symptoms were thoracico-abdominal in three and abdominal in eight; these cases were evaluated as acute in three, acute upon chronic in two, and chronic in six. There was a significant delay in the diagnosis in all cases (except a neonate in the series), and no case was diagnosed on clinical grounds alone.THE PREDISPOSING FACTORS (EXCEPT THE CLINICAL MISDIAGNOSIS OF THE NEONATE) IN SIX OF THE SEVEN CASES THAT CAME TO SURGERY WERE: diaphragmatic hernia and perigastritis (left lung abscess, thoracic empyema), arteriomesenteric compression of the duodenum in pregnancy (peptic ulcer), splenomegaly (hepatosplenomegaly, ascites, esophageal varices), previous gastrojejunostomy (stomal ulcer, left subphrenic abscess) and two cases of intestinal malrotation with mesenteric abnormalities (small bowel obstruction in one and duodenal atresia in the other). In one idiopathic case, gastric outlet obstruction was clinically suspected prior to surgery. Thus, the putative rarity of GV in black Africans is not supported by this experience.Gastric volvulus is a clinico-radiologic entity that may present with a confusing thoracico-abdominal symptom complex. A greater awareness of the radiologic features is quintessential to an expeditious and usually successful surgical management that will avoid potentially serious complications. Negative surgical findings do not exclude GV as the underlying cause of acute abdomens necessitating emergency laparotomies.

Volvulus of sigmoid colon and cecum is not uncommon in tropical Africa, but gastric volvulus is relatively rare, especially when compared with various causes of peptic ulcer syndrome seen at the University College Hospital in Ibadan, Nigeria.A case of chronic intermittent type of gastric volvulus with superficial gastric ulcerations was recently seen and treated by vagotomy, pyloroplasty, and gastropexy.Predisposing factors, various types, presentations, and management of gastric volvulus are discussed.Since an acute attack of gastric volvulus, which is rare and possibly fatal if not adequately treated, can be confused with gastric outlet obstruction resulting from chronic duodenal ulcer, which is common, an index of suspicion is essential for the diagnosis of gastric volvulus.

Over a four year period, from August 1987 to July 1991, thirteen cases of chronic and recurrent gastric volvulus were encountered comprising six paediatric and seven adult patients. In none of the patients was the condition clinically suspected; diagnosis being made only at meticulous upper gastro-intestinal (UGI) barium series. The paediatric patients typically presented with obstructive symptoms of projectile vomiting especially after meals and failure to thrive. The adults had variable symptoms of dyspepsia, recurrent intermittent upper abdominal discomfort or pain, occasionally accompanied by vomiting or retching mimicking many different upper abdominal conditions, such as peptic ulcer, biliary tract or pancreatic disease but with negative findings at endoscopy and abdominal ultrasound scanning. All cases were organo-axial type of gastric volvulus. Associated conditions were small sliding hiatus hernia in two adult cases; partial small bowel malrotation in two cases, high jejunal obstruction also in two cases and congenital hip dislocation in one patient. An infant had umbilical hernia, previous meconium cyst and meconium peritonitis. The condition seems not as uncommon as previously thought; the key to diagnosis being constant awareness, a high index of clinical suspicion and a carefully performed UGI barium series especially during the attack of pain.

Considerable advances are occurring in the application of laparoscopic techniques to gastrointestinal and hepatobiliary disorders. Following studies in experimental animals, surgeons with an interest in gastroduodenal disease have now introduced laparoscopic techniques into current surgical practice. Elective intervention for peptic ulcer disease is currently being established, particularly in patients with proven negative Helicobacter pylori (HP) status, or when eradication has proved unsuccessful with various drug regimens. In addition, emergency laparoscopic intervention for perforation is gaining acceptance, with or without a definitive anti-ulcer procedure. Therapeutic endoscopy for bleeding peptic ulcer may well be followed by anti-ulcer laparoscopic surgery in selected patients. Laparoscopic techniques have been utilized for the treatment of Mallory Weiss tear, congenital hypertrophic pyloric stenosis, Dieulafoy's lesion, gastric trauma or volvulus and benign gastric tumours. More ergonomic instruments are required before laparoscopic gastric resection becomes more widely acceptable. It is essential that objective evaluation of variations on vagotomy themes be undertaken in prospective clinical trials and that the safety and efficacy of gastric resection procedures be substantiated if this renaissance is to revolutionize gastroduodenal surgical practice.

This review illustrates the changing paradigms in the understanding of the pathogenesis of pneumatosis intestinalis. Although many theories have been evoked, pragmatically there appear to be four major clinical and diagnostic imaging considerations. The most common and most emergent life-threatening cause of intramural bowel gas is the result of bowel necrosis due to bowel ischemia, infarction, necrotizing enterocolitis, neutropenic colitis, volvulus, and sepsis. In the stomach, intramural gas can be caused by emphysematous gastritis or ingestion of caustic agents. These situations represent surgical emergencies. Pneumatosis is found secondary to mucosal disruption presumably due to over-distention from peptic ulcer, pyloric stenosis, annular pancreas, and even to more distal obstruction. Disruption can also be caused by ulceration, erosions, or trauma, including the trauma of child abuse. Disruption can also be iatrogenic from intracatheter jejunal feeding tubes, stent perforation, sclerotherapy, or surgical or endoscopic trauma. In these cases, the gas may be focal or linear. Treatment depends on the extent of the disruption and the underlying cause. A more subtle form of mucosal disruption may occur due to mucosal erosions and also to defects in intestinal crypts secondary to acute and subclinical enteritides that allow intraluminal bacterial gas under pressure to percolate into the bowel wall layers, particularly the submucosa (29). Pneumatosis, often linear or cystic in appearance, is seen with increased frequency in patients who are immunocompromised because of steroids, chemotherapy, radiation therapy, or AIDS. In these cases, the pneumatosis may result from intraluminal bacterial gas entering the bowel wall due to increased mucosal permeability caused by defects in bowel wall lymphoid tissue. Clinical and imaging findings are important in the differentiation of this transient pneumatosis from fulminant life-threatening causes in this subset of patients. A pulmonary cause must still be considered in cases of chronic obstructive pulmonary disease, asthma, and cystic fibrosis. It can occur with barotrauma and after chest tube placement. It may relate to increased intrathoracic pressure associated with retching and vomiting. The possibility remains that occasionally the origin of pneumatosis intestinalis will remain cryptogenic--caused but unexplained.

A retrospective analysis was undertaken on 229 cases of acute surgical abdomen surgically managed at Yirgalem hospital from January to December 1997. Small intestinal obstruction ranked the first and it was mainly due to small intestinal volvulus. Acute appendicitis was the second in the rank. Large intestinal obstruction was the third and it was mainly due to sigmoid volvulus. Typhoid perforation, primary peritonitis, perforated gastroduodenal ulcer, abdominal tuberculosis and empyema of the gallbladder in that order were the other observed causes of acute surgical abdomen. Analysis based on the specific causes of acute abdomen is of great value for early diagnosis and prompt treatment in clinical practice.

Surgical emergencies can be missed easily in children, who are not always able to volunteer relevant information. Awareness of the entities discussed in this review might help the EP uncover subtle clues to early diagnoses that might not be initially apparent. Ill-appearing children who have abdominal pain and vomiting should be considered to have ischemic or necrotic bowel until proven otherwise. Possible diagnoses include volvulus, intussusception, and necrotizing enterocolitis. Bilious vomiting, especially in a young infant, should be considered to be an indication of a high bowel obstruction such as midgut volvulus, which warrants immediate surgical consultation. Significant rectal bleeding with abdominal pain can result from intussusception, volvulus, or an inflamed Meckel's diverticulum. Rectal bleeding with unstable vital signs can result from an upper GI bleed (eg, peptic ulcer disease). Painless rectal bleeding can result from a Meckel's diverticulum, polyps, arteriovenous malformation, or a tumor. Examination of the genitalia is imperative, especially in boys, to exclude the possibility of an incarcerated hernia or testicular torsion.
