    Abstract:
    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 can be surgically altered. Aside from conversion to distal bypass, which may have significant negative nutritional sequelae, revisional surgery for this group of patients has not often been reported. The addition of adjustable silicone gastric banding (ASGB) to Roux-en-Y gastric bypass (RYGBP) may be a useful revision strategy because it has potential safety benefits over other revisional approaches. MATERIALS AND METHODS: We report on 8 patients who presented with inadequate weight loss or significant weight regain after proximal gastric bypass. All patients underwent revision with the placement of an ASGB around the proximal gastric pouch. Bands were adjusted at 6 weeks postoperatively and beyond as needed. Complications and weight loss at the most recent follow-up visit were evaluated. RESULTS: Mean age and body mass index (BMI) at the time of revision were 39 +/- 9.9 years and 44.0 +/- 4.5 kg/m2 respectively. No patients were lost to follow-up, and they lost an average of 38.1 +/- 10.4% and 44.0 +/- 36.3% of excess weight and 49.1 +/- 20.9% and 52.0 +/- 46.0% of excess BMI in 12 and 24 months respectively. Patients lost an average of 62.0 +/- 20.5% of excess weight from the combined surgeries in 67 (48-84) months. The only complication was the development of a seroma overlying the area of the port adjustment in one patient. There have been no erosions or band slippages to date. CONCLUSIONS: These results indicate that the addition of an ASGB causes significant weight loss in patients with poor weight loss outcome after RYGBP. The fact that no anastomosis or change in absorption is required may make this an attractive revisional strategy. Long- term evaluation in a larger population is warranted.
