Adjustable Banded Gastric Bypass as a Revisional Bariatric Procedure after Gastric Bypass
Marc Bessler MD; Amna Daud MD, MPH; Daniel Davis DO.
Center for Obesity Surgery, New York-Presbyterian Hospital and Columbia University, New York, NY.
Background: Inadequate weight loss after proximal gastric bypass presents a clinical challenge to bariatric surgeons. Pouch size, stoma size and limb length are the variables that the surgeon can control/modify. Aside from conversion to distal bypass, which may have significant negative nutritional squelae, revisional surgery for this group of patients has not often been reported. The use of non-adjustable banded bypass has been reported as a primary procedure. The addition of Adjustable Silicone Gastric Banding (ASGB) to Gastric Bypass (GBP) may be a useful revision strategy as it has potential safety benefits over other revisional approaches.
Methods: We report on 7 patients who presented with inadequate weight loss or significant weight gain after proximal Gastric Bypass. All patients underwent revision with the placement of an Adjustable Silicone Gastric Band around the proximal pouch of their Gastric Bypass. Bands were adjusted at 6 weeks post operatively and beyond as needed. Complications, weight loss at the most recent follow up visit were evaluated.
Results: Mean age and BMI at the time of revision was 36.7 (30-49) years and 45.7 ± 3.32 (kg/m2).No patients were lost to follow up which ranged from 2 weeks to 14 months (mean=) and they lost 7%-59% (mean %EWL=26%) of their excess weight respectively. The only complication was the development of a seroma overlying the area of band port in one patient.
Conclusion: These results indicate that the addition of the ASGB causes significant weight loss in patients with weight regain after GBP. The fact that no anastomosis or change in absorption is required may make this an attractive revisional strategy.
