Abstract

Results: Twenty-two patients with a history of RYGB and 56 with a history of VBG were identified. Following the revisional procedure, the RYGB group experienced 35.8% excess weight loss (%EWL) and a 31.8% morbidity rate. For the VBG group, patients experienced a 46.2% %EWL from their weight before the revisional operation with a 51.8% morbidity rate. Co-morbidity remission rate was excellent. Diabetes (VBG:100%, RYGB: 85.7%), gastroesophageal reflux disease (VBG: 94.4%, RYGB: 80%), and hypertension (VBG: 74.2%, RYGB:60%) demonstrated significant improvement.

Background: Patients having previous bariatric surgery are at risk for weight regain and return of co-morbidities. If an anatomic basis for the failure is identified, many surgeons advocate revision or conversion to a Roux-en-Y gastric bypass. The aim of this study was to determine whether revisional bariatric surgery leads to sufficient weight loss and co-morbidity remission.

Conclusion: Revision of a failed RYGB or conversion of a VBG to a RYGB provides less weight loss and a higher complication rate than primary RYGB but provides an excellent opportunity for co-morbidity remission. (Surg Obes Relat Dis 2014;10:654660.).

Patients and Methods: From 2005-2012, patients undergoing revision were entered into a prospectively maintained database. Perioperative outcomes, including complications, weight loss, and co-morbidity remission, were examined for all patients with a history of a previous vertical banded gastroplasty (VBG) or Roux-en-Y gastric bypass (RYGB).
