Post-jejunoileal-bypass hepatic disease. Its similarity to alcoholic hepatic disease

The authors studied serial hepatic biopsies of five patients who developed hepatic failure following jejunoileal bypass for extreme obesity, with autopsies of two. The hepatic histologic changes included centrilobular or focal alcoholic hyalin, intrasinusoidal collagenosis, fatty hydropic degeneration, and neutrophilic infiltrate. At least two of the patients were abstinent from alcohol, both prior to and after the surgical procedures. The others, after the bypass procedures, had reduced alcohol consumption from previous levels. All patients developed hepatic failure and histologically progressive hepatic disease with alcoholic hyalin and other changes indistinguishable from alcoholic hepatic disease in 21/2 to 5 months, in spite of hyperalimentation and re-establishment of intestinal continuity in four. Nausea, vomiting, abdominal pain and ascites were prominent complaints. Four of the five patients died in hepatic failure. The authors conclude that these cases of progressive hepatic disease with histologic changes simulating those found in livers of alcoholic patients offer evidence that heavy alcohol consumption may affect the liver in an indirect fashion.
