Radiologic findings and medical records of 27 patients with angiographic documentation of splenic vein occlusion were reviewed. The most common causes were pancreatic carcinoma, pancreatitis, and malignant lymphoma. Radiographic findings which suggest splenic vein occlusion are gastric varices without esophageal varices and collateral veins in the left upper abdomen during the vascular phase of rapid sequence pyelography. Additional features may be associated with the underlying disease, such as pancreatic calcification and upper abdominal mass lesions. The diagnosis is usually confirmed by high dose celiac or splenic angiography. Examination of the stomach with barium for the detection of gastric varices is more sensitive than has been previusly recognized; features which suggest them are described. Isolated gastric varices may be a clue to isolated splenic vein occlusion and its underlying causes.

Twenty patients with massive abdominal hemorrhage related to chronic pancreatitis, pancreatic neoplasms and arteriovenous malformations were studied angiographically. Abdominal hemorrhage drained most frequently into the gastrointestinal tract, but also flowed through cutaneous drain sites and fistulas, intraperitoneally, into pseudocysts and once into a large pancreatic tumor. The most common angiographic observation in pancreatitis was pseudoaneurysm formation. Both patients with arteriovenous malformation had dilated, racemose feeding arteries and early dense filling of the draining veins. Three patients had pancreatic carcinoma and documented bleeding from gastroesophageal varices related to portal or splenic vein occlusion by the tumor. Five patients were treated by vasopressin infusion, balloon tamponade, or therapeutic embolization.

The frequency of splenic vein obstruction secondary to pancreatic or retroperitoneal diseases has been only recently appreciated. The diagnosis is important because it frequently results in development of gastric and duodenal varices. It is often assumed that the diagnosis should only be suspected in patients with splenomegaly. This report describes 19 patients in whom splenic vein thrombosis was diagnosed by angiography although clinically unsuspected. In 11, the spleen was normal in size although extensive gastric varices were present. In 3 patients the presenting problem was massive hematemesis. Review of the upper gastrointestinal examinations in these patients showed thickened gastric or duodenal folds although in the absence of esophageal varices, the diagnosis was not made prior to angiography. More liberal use of angiography in patients with an appropriate clinical background, such as a history of pancreatitis, may lead to earlier and more frequent diagnosis of splenic vein obstruction. Varices that result from splenic vein obstruction can be cured by splenectomy.

A patient with recurrent gastrointestinal bleeding was found to have varices at the splenic flexure at colonoscopy. Angiography revealed complete occlusion of the splenic vein. Although the patient did not have cirrhosis, he did have a history of pancreatitis which presumably was responsible for the splenic vein thrombosis. This case represents a compartmentalized form of portal hypertension which requires careful endoscopic and radiographic studies for proper evaluation. Successful treatment was accomplished by splenectomy.

A case of a 48 year old male with a history of alcohol abuse, chronic relapsing pancreatitis, and massive hemorrhage into the small intestine is reported. The patient had previously undergone a cholecystojejunostomy. Imaging studies demonstrated occlusion of the splenic, superior mesenteric, and distal portal veins with large varices in the jejunum. He recovered following jejunal resection and Roux-en-Y cholecystojejunostomy. The mechanism for formation of varices in the small bowel in this clinical setting is discussed.

A patient with an uncommon cause of portal venous hypertension, pancreatitis, is depicted. The patient had an equally uncommon pattern of symptoms and signs consisting of abdominal pain and lower gastrointestinal hemorrhage caused by colonic varices. A unique treatment, with angiographic placement of an expandable intraluminal stent within the portal vein, was employed to reopen the portal venous system and reduce portal pressure. Relief of bleeding was accomplished and sustained for more than 1 year.

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.

Lesions of the colon are generally considered to be sequelae of pancreatitis. They include: localized paralytic ileus (colon cutoff sign), necrosis, fistulae, stenosis and varices. On the basis of an extensive review of the literature (332 cases), it is suggested that the real incidence of these lesions is significant. The anatomic relationship of the large bowel to the pancreas is an important factor in the genesis and localization of the lesions. Enzymatic-inflammatory and ischemic processes are involved in the most highly supported theories. Each complication shows different diagnostic and clinical patterns. In this paper, six cases of such lesions are presented, including 2 cases of necrosis, 2 of stenosis, 1 of fistula and 1 case of localized paralytic ileus.

During the period from 1971 to 1988 there were 212 fatalities out of 24,822 obductions because of gastrointestinal bleeding. Bleeding from oesophagus varices was most often found, followed by bleeding from duodenal ulcer (16%), gastric ulcer (14%) and haemorrhagic gastritis (11%). The sex-ratio was 2:1 in favour of men. In most cases alcohol related problems were found (with organic diseases such as fat liver, liver cirrhosis, pancreatitis as well as social deprivation, sometimes with acute alcoholization.

Portal and splenic venous thrombosis is a rare but well recognised complication of pancreatic carcinoma and pancreatitis. We report a series of five patients with pancreatic disease in whom CT detected this complication. The appearances on CT are of an enlarged vein with a centre of lower attenuation which does not enhance following intravenous contrast injection, ring enhancement and opacification of collateral veins. Splenic vein thrombosis following pancreatitis should be considered in all patients with pancreatic disease as this complication is increasingly recognised as a cause of upper gastrointestinal haemorrhage from varices.
