Abstract

Background: Placement of an adjustable gastric band (AGB) over the gastric pouch after RYGB failure has had varied results. The aim of this study was to evaluate safety and outcomes of AGB after RYGB failure.

Methods: Twenty-eight patients who underwent laparoscopic placement of an AGB around the gastric pouch as a revisional procedure for inadequate weight loss or recidivism after RYGB between 2008-2011 were identified.

Results: Twenty-four (86%) patients had a dilated gastric pouch and/or stoma. The mean operative and adhesiolysis times were 137.9±52.3 minutes and 83±51 minutes, respectively. History of a previous open RYGB was associated with a longer adhesiolysis time (P = .03). Three (11%) major intraoperative and 5 (18%) early postoperative complications occurred. Late complications (all requiring band removal) were observed in 6 (21%) patients and included ineffectiveness (n = 2), dysphagia/esophageal dilation (n = 2), band erosion (n = 1), and peritonitis (n = 1). In all 4 patients with a normal-sized pouch and stoma at the time of band placement, the band was removed. After a mean follow-up of 38.3±14.8 months, the mean body mass index (BMI) change and median excess weight loss (EWL) after salvage banding were -3.6±4.5 kg/m(2) and 12.7%, respectively. In the subset of patients with a dilated pouch/stoma, BMI less than 42 kg/m(2) at the time of band placement was associated with a significantly higher EWL (41.4%±37.0%) compared with a baseline BMI>42 kg/m(2) (12.1%±7.2%, P = .03).

Conclusions: Salvage banding is technically challenging due to dense adhesions, carries significant morbidity, and is associated with only 13% additional EWL. However, this approach may still be an option in carefully selected patients, such as those with previous laparoscopic RYGB who have a dilated pouch and/or stoma and lower BMI.
