Liver injury with alcoholiclike hyalin after gastroplasty for morbid obesity.

Hepatic damage resembling alcoholic hepatitis has been described after jejunoileal bypass surgery for morbid obesity, but has not been previously reported as a complication of gastric partitioning operations (gastric bypass and gastroplasty). A patient who developed an alcoholic hepatitislike clinical picture 8 mo after gastroplasty is described, suggesting that malnutrition superimposed on obesity may be responsible for the injury in both settings. Reversal of the gastroplasty was associated with clinical and biochemical improvement.
