Patterns of hepatic morphology in jejunoileal bypass patients.

The close similarity of the hepatic histological pattern in two conditions, I) jejunoileal bypass and 2) chronic alcoholism, is described, including the inconstancy of development of permanent hepatic changes in both conditions. It appears that serious hepatic disease develops in an incidence between 1 and 17% of patients who have received the operation. Hepatic disease presents itself as: 1) acute hepatic failure, 2) insidious development of cirrhosis, or 3) tenous hepatic functional state that reduces hepatic resistance to other insults.
