Background: Severe obesity is common before and after liver transplantation and has been associated with significant morbidity and mortality. Furthermore, it may cause graft dysfunction through the development of recurrent nonalcoholic steatohepatitis.
Methods: We performed Roux-en-Y gastric bypass in two morbidly obese patients who had undergone liver transplantation and had graft dysfunction secondary to recurrent nonalcoholic steatohepatitis.
Results: Both patients demonstrated dramatic weight loss and had normalization of liver enzymes, lipids, and glucose levels. Repeated liver biopsy showed regression of steatosis.
Conclusions: Roux-en-Y gastric bypass can be successfully performed in liver transplant recipients with morbid obesity and may lead to weight loss, correction of metabolic abnormalities, and regression of hepatic dysfunction secondary to recurrent steatosis.
