Efficiency of Laparoscopic One-Step Revision of Failed Adjusted Gastric Banding to Gastric Sleeve: a Retrospective Review of 101 Consecutive Patients

Background Until recently, laparoscopic adjustable gastric banding (LAGB) was one of the most commonly performed bariatric surgeries worldwide. Today, its high rate of complications and failure rates up to 70% requires revisional surgery. The one-stage conversion from LAGB to laparoscopic sleeve gastrectomy (LSG) has been shown to be safe, although there are some concerns on efficacy and long-term weight loss. Objectives To demonstrate that one-step revision of LAGB to another restrictive procedure, such as LSG, might have efficient long-term outcomes. Methods The charts from 133 revisional LSGs for failed or complicated LAGB were retrospectively reviewed for the period between January 2010 and August 2017. Thirty-two patients were excluded for loss to follow-up. Demographics, complications, and percentage of excess weight loss (%EWL) were determined. Results One hundred one patients were included (85 women and 16 men), with a mean age of 48.5 years, and a mean body mass index of 47.1 kg/m 2 . During the follow-up, 15 patients (15%) underwent a second revisional surgery for weight loss failure (8 Roux-en-Y gastric bypass (RYGBP), 3 biliopancreatic diversion, 3 single anastomosis duodenal-ileal bypass, 1 revisional LSG). Ten patients (10%) had long-term complications (8 severe reflux and 2 stenosis) during this period and underwent a second revisional surgery (10 RYGBP). The remaining 76 had a mean follow-up of 4.3 years and a mean %EWL of 53.2%. Conclusion Single-stage conversion to LSG is a safe and appropriate solution for failed or complicated LAGB with good long-term weight loss.
