Five-year outcomes of revisional bariatric surgery: gastric band to sleeve gastrectomy or to Roux-en-Y gastric bypass

Revisional bariatric surgery after an index adjustable gastric band (AGB) may be indicated to remedy weight relapse or band-related complications. We examined outcomes five years following revision from AGB to laparoscopic sleeve gastrectomy (AGB-LSG) or to Roux-en-Y gastric bypass (AGB-RYGB). We conducted a retrospective review to identify patients (men and women, age 18–80) who underwent one revisional bariatric procedure with AGB as the index procedure at two medical centers in our healthcare system between January 2012 and February 2017. We only included patients with a pre-revision BMI > 30 kg/m2 for whom 5-year follow-up data were available. We compared 5-year weight loss and remission of comorbidities in patients undergoing AGB-LSG and AGB-RYGB conversion. A total of 114 patients met inclusion criteria (65 AGB-LSG, 49 AGB-RYGB). At 5-year post-revision, percent total weight loss (3.4
