Liver Transplantation and Bariatric Surgery: Timing and Outcomes

Nonalcoholic steatohepatitis (NASH) is projected to become the leading indication for liver transplantation (LT) in the next decade in the United States. Strategies to treat the underlying etiology of NASH, which is almost always obesity, are being pursued. One such strategy is the utilization of bariatric surgery (BS) in the peritransplant period. The use of BS prior to LT could prevent the progression of NASH and abrogate the need for LT. BS at the time of LT or postoperatively has the potential to not only improve obesity‐associated conditions such as diabetes, but also the potential to influence the incidence of NASH in the post‐LT setting. However, there continues to be no consensus on the use and timing of BS in this patient population. This review aims to discuss the current literature and possible future action.
