Conversion and revisional surgery: Roux-en-Y gastric bypass

Abstract

Gastric bypass has proven to be an effective operation in terms of both weight loss and resolution of comorbid conditions. However a subset of patients will require revision for complications and technical mishaps incurred at the index operation. In other patients, gastric bypass will fail to produce adequate weight loss or will have weight regain. In some this will lead to recurrence or development of de novo comorbid conditions. These patients may also benefit from revisional operations.
