Laparoscopic Roux-en-Y gastric bypass is safe and feasible after orthotopic liver transplantation.

Liver transplantation has become a life-saving procedure for patients with end-stage liver disease. Since obesity is rampant in our society, it is not surprising that patients with a liver transplant suffer from obesity as well. In addition, Roux-en-Y gastric bypass (RYGBP) is a life-saving procedure for patients suffering from morbid obesity. However, a liver transplant is an extensive and invasive abdominal procedure. Further operations after orthotopic liver transplantation may be challenging. With increasing surgeon experience and technical advancements in laparoscopic equipment, previous abdominal surgery is no longer a contraindication to utilize the laparoscopic approach for RYGBP. In fact, herein, we describe the first laparoscopic RYGBP after orthotopic liver transplantation in the world literature.
