The lateral decubitus view of the barium-filled stomach has been reassessed in a series of 42 patients with possible splenic rupture and compared with a group of 17 patients with splenomegaly. Displacement of the gastric fundus of more than 4 cm from the inner rib margin is highly suggestive of splenic rupture. Where doubt exists, the test should be repeated within a short while. Peritoneal lavage and a full blood count investigation both add to the diagnostic accuracy.

In seven children the clinical course of extrahepatic portal vein stenosis was studied angiographically. In all children with splenomegaly it was deemed necessary to perform an X-ray barium examination of the oesophagus. Transsplenic portal venography was performed when oesophageal varices were detected to set up the best scheme for emergency treatment. In our patients with hypersplenism there were no specific bone marrow alterations. In contrast to the literature most of our cases had fibrosis of the liver.

Plain films of the abdomen in advanced states of schistosomiasis reveal massive splenomegaly without evidence of splenic calcification. The liver may be enlarged in the early stages but ultimately decreases and becomes small. Ascites is evident in far advanced disease. Chest films are negative in the early stages, but in advanced disease, dilated pulmonary arteries, right ventricular enlargement, and dilatation of the azygous vein may be recognized. Granulomata are seen as multiple small rounded densities scattered throughout both lung fields. The routine barium swallow will reveal unsuspected esophageal varices. Nine patients were studied preoperatively by panhepatic angiography and 14 post-operatively following splenorenal shunt. Thrombosis of the shunt and hepatic encephalopathy were common postoperative complications.

Isolated bleeding gastric varices due to a spontaneous idiopathic thrombosis of the splenic vein was found to be the cause of obscure, painless recurrent bleeding in our patient. The diagnosis of spontaneous splenic vein thrombosis should be considered in the presence of gastrointestinal bleeding with unexplained splenomegaly. Prominent gastric folds may be the only barium contrast or endoscopic finding often lacking esophageal varices. Arteriography is essential in demonstrating an obstructed splenic vein. Splenectomy is the treatment of choice of "left-sided" portal hypertension.

Recent studies have shown that involvement of the gastrointestinal tract is much more frequent than originally reported in patients with systemic mastocytosis. Seventy percent to 80% of patients with systemic mastocytosis are found to have gastrointestinal symptoms when a careful history is taken, and abnormalities in the gastrointestinal tract are frequently detected by endoscopic studies, functional studies of absorption, and barium studies. Because of the rarity of the disease, there are few prospective studies of gastrointestinal involvement, so the actual frequency of upper and lower gastrointestinal lesions is unknown. Furthermore, there have been no studies correlating endoscopic abnormalities of the lower gastrointestinal tract with the presence or absence of diarrhea, which is a frequent symptom (mean, 43% [range 14%-100%]). A review of gastric acid studies reveals that a proportion of patients develop gastric acid hypersecretion because of the hyperhistaminemia, which can result in ulcer disease that in turn can cause dyspeptic pain, small intestinal mucosal damage, and malabsorption. In some patients gastric acid hypersecretion in the range seen in Zollinger-Ellison syndrome can develop. A number of studies suggest that the prevalence of peptic ulcer disease has been underestimated in these patients and is certainly higher than the general population. The exact physiologic basis for the diarrhea or nondyspeptic abdominal pain remains largely unknown in these patients. Whereas some studies suggest small intestinal mucosal abnormalities are responsible for most cases of malabsorption not associated with gastric acid hypersecretion, this supposition also remains unproven. Hepatomegaly, portal hypertension, splenomegaly, and ascites occur frequently in patients with systemic mastocytosis, especially those with category II through IV disease. Whereas the histology of the liver and spleen and alterations in hepatic function studies have been well studied, the pathogenesis of each of these abnormalities has not been well studied, and almost all the information comes from a few well-studied case reports.
