Gastric banding as a salvage procedure for patients with weight loss failure after Roux-en-Y gastric bypass.

Background: This study reviews outcomes after laparoscopic adjustable gastric band (LAGB) placement in patients with weight loss failure after Roux-en-Y gastric bypass (RYGBP).

Methods: All data was prospectively collected and entered into an electronic registry. Characteristics evaluated for this study included pre-operative age and body mass index (BMI), gender, conversion rate, operative (OR) time, length of stay (LOS), percentage excess weight loss (EWL), and postoperative complications.

Results: 11 patients (seven females, four males) were referred to our program for weight loss failure after RYGBP (six open, five laparoscopic). Mean age and BMI pre-RYGBP were 39.5 years (24-58 years) and 53.2 kg/m(2) (41.2-71 kg/m(2)), respectively. Mean EWL after RYGBP was 38% (19-49%). All patients were referred to us for persistent morbid obesity due to weight loss failure or weight regain. The average time between RYGBP and LAGB was 5.5 years (1.8-20 years). Mean age and BMI pre-LAGB were 46.1 years (29-61 years) and 43.4 kg/m(2) (36-57 kg/m(2)), respectively. Vanguard (VG) bands were placed laparoscopically in most patients. There was one conversion to open. Mean OR time and LOS were 76 minutes and 29 hours, respectively. The 30-day complication rate was 0% and mortality was 0%. There were no band slips or erosions; however, one patient required reoperation for a flipped port. The average follow-up after LAGB was 13 months (2-32 months) with a mean BMI of 37.1 kg/m(2 )(22.7-54.5 kg/m(2)) and an overall mean EWL of 59% (7-96%). Patients undergoing LAGB after failed RYGBP lost an additional 20.8% EWL (6-58%).

Conclusion: Our experience shows that LAGB is a safe and effective solution to failed RYGBP.
