Weight gain is a frequent postoperative complication following a solid organ transplant which can be solved by bariatric surgery. The outcomes of bariatric surgery among patients with an organ transplant history are always a challengeable subject for surgeons and surgery candidates. In this review article, we aim to investigate the existence literature about the rates of morbidity and mortality, frequent complications in terms of graft function, remission in diabetes, hypertension, pulmonary and cardiovascular disorders, hepatic and renal functions, and immunosuppressive stability, as well as the safety of bariatric surgery among patients.

Keywords: Bariatric surgery, Organ transplantation, Complications

Core Tip: In this minireview article, we try to provide a broad introduction to the impacts of bariatric surgery on organ transplantation outcomes rather than as an exhaustive review. Moreover, this review will focus on major transplantations and type of bariatric surgery among morbidly obese patients. Within the broad categories of organ transplantation, we then conclude with remarks about the outcomes of bariatric surgery among patients with combined organ transplantation. Where possible, the readers are suggested to refer to the numerous comprehensive clinical studies reporting the predictors of adverse outcomes of organ transplantation following bariatric surgery.
