Reoperative bariatric surgery: a systematic review of the reasons for surgery, medical and weight loss outcomes, relevant behavioral factors.

Reoperative surgery following the failure of primary bariatric surgery is increasing due to the significant rates of patients experiencing poor weight loss or medical complications. This literature review was conducted to organize the emerging, but scattered, literature regarding the reasons for undergoing surgery, the best available options, the predictors of success, and the psychological characteristics of patients submitted to reoperative surgeries. Reoperative procedures are technically challenging, but the possible benefits of reoperation supplant the increased risks associated with these procedures. The etiology of reasons for undergoing a second surgery includes medical (e.g., fistula, ulcer disease) and behavioral aspects. Factors that may compromise outcomes have not been much studied. Particular attention should be paid to candidates with a history of difficulties in engaging in healthy eating patterns.- This research was partially supported by Fundacao para a Ciencia e a Tecnologia/Foundation for Science and Technology through a European Union COMPETE program grant to Eva Conceicao (IF/01219/2014) and doctoral scholarship (SFRH/BD/104159/2014) to Ana Pinto-Bastos.
