Single-stage revision from gastric band to gastric bypass or sleeve gastrectomy: 6- and 12-month outcomes.
Laparoscopic adjustable gastric banding (LAGB) is increasingly requiring revisional surgery for complications and failures. Removal of the band and conversion to either laparoscopic Roux-en-y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) is feasible as a single-stage procedure. The objective of this study is to compare the safety and efficacy of single-stage revision from LAGB to either LRYGB or LSG at 6 and 12 months postoperatively.



Retrospective analysis was performed on patients undergoing single-stage revision between 2009 and 2014 at a single academic medical center. Patients were reassessed for weight loss and complications at 6 and 12 months postoperatively.



Thirty-two patients underwent single-stage revision to LRYGB, and 72 to LSG. Preoperative BMIs were similar between the two groups (p = 0.27). Median length of stay for LRYGB was 3 days versus 2 for LSG (p = 0.14). Four patients in the LRYGB group required reoperation within 30 days, and two patients in the LSG group required reoperation within 30 days (p = 0.15). There was no difference in ER visits (p = 0.24) or readmission rates (p = 0.80) within 30 days of operation. Six delayed complications were seen in the LSG group with three requiring intervention. At 6 months postoperatively, percent excess weight loss (%EWL) was 50.20 for LRYGB and 30.64 for LSG (p = 0.056). At 12 months, %EWL was 51.19 for LRYGB and 34.89 for LSG (p = 0.31). There was no difference in diabetes or hypertension medication reduction at 12 months between LRYGB and LSG (p > 0.07).



Single-stage revision from LAGB to LRYGB or LSG is technically feasible, but not without complications. The complications in the bypass group were more severe. There was no difference in readmission or reoperation rates, weight loss or comorbidity reduction. Revision to LRYGB trended toward higher rate and greater severity of complications with equivalent weight loss and comorbidity reduction.
