The long-term follow-up of patients with the severe form of Manson's schistosomiasis who had had elective surgical treatment for portal hypertension, in a randomized trial, was clinically evaluated. Of 94 patients, proximal splenorenal shunting was performed in 32, esophagogastric devascularization with splenectomy in 32 and distal splenorenal shunting in(More)
The size of gastroesophageal varices is one of the most important factors leading to hemorrhage related to portal hypertension. An endoscopic evaluation of the size of gastroesophageal varices before and after different operations for portal hypertension was performed in 73 patients with schistosomiasis, as part of a randomized trial: proximal splenorenal(More)
Total serum lipids, as well as apolipoproteins A-I (apo A-I) and B (apo B), were determined in 74 patients with chronic liver failure without cholestasis and in 82 normal subjects. The VLDL, LDL and HDL lipid fractions were reduced in the liver failure group by 36%, 24% and 46%, respectively (P < 0.001). Apolipoproteins A-I and B were also reduced by 26%(More)
Percutaneous deposition of radioactive xenon in the hepatic parenchyma is suggested as a technique for estimating the hepatic blood flow. The authors applied this procedure, which can be repeated at very short intervals, twice in 5 patients suffering from schistosomiasis, and in 6 controls. The percentage of deviation from the mean was calculated by means(More)
