BackgroundDespite its worldwide popularity, laparoscopic adjustable gastric banding (LAGB) requires revisional surgery for failures or complications, in 20-60% of cases. The purpose of this study was to compare in terms of efficacy and safety, the conversion of failed LAGB to laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy. (LSG).MethodsThe bariatric database of our institution was reviewed to identify patients who had undergone conversion of failed LAGB to LRYGB or to LSG, from November 2007 to June 2012.ResultsA total of 108 patients were included. Of these, 74 (68.5%) underwent conversion to LRYGB and 34 to LSG. All of the procedures were performed in 2-stage and laparoscopically. The mean follow-up for the LRYGB group was 29.1±17.9 months while for the LSG patients was 24.2±14.3 months. The mean body mass index (BMI) prior LRYGB and LSG was 45.6±7.8 and 47.5±5.6 (P = .09), respectively. Postoperative complications occurred in 16.2% of the LRYGB patients and in 2.9% of the LSG group (P = .04). Mean percentage of excess weight loss was 59.9%±16.2% and 70.2%±16.7% in LRYGB, and it was 52.2%±11.4% and 59.9%±14.4% in LSG at 12 months (P = .007) and 24 months (P = .01) after conversion.ConclusionIn this series, LRYGB and LSG are both effective and adequate revisional procedure after failure of LAGB. While LRYGB seems to ensure greater weight loss at 24 months follow-up, LSG is associated with a lower postoperative morbidity.Copyright © 2014 American Society for Bariatric Surgery.
