Abstract:
Revisional bariatric procedures are increasingly common. With more primary procedures being performed to manage severe obesity and its complications, 5% to 8% of these procedures will fail, requiring revisional operation. Reasons for revisional bariatric surgery are either primary inadequate weight loss, defined as less than 25% excess body weight loss, or weight recidivism, defined as a gain of more than 10 kg based on the nadir weight; however, each procedure also has inherit specific complications that can also be indications for revision. This article reviews the history of each primary bariatric procedure, indications for revision, surgical options, and subsequent outcomes.
