Purpose
The optimal revisional bariatric surgery procedure following a previous failed gastric band surgery is yet to be determined. The aim of our study was to compare single- and two-stage laparoscopic sleeve gastrectomy (LSG) following laparoscopic adjustable gastric banding (LAGB) in terms of short- and mid-term outcomes.
Materials and Methods
Patients who underwent LSG after a failed LAGB in Israel during 2014–2017 were included. Data were obtained from the Israeli National Bariatric Surgery Registry. Data analyzed included comorbidities, postoperative complications, and anthropometric outcomes.
Results
Of 595 patients included in the data analysis, 381 (64%) underwent one-stage and 214 (36%) had two-stage LSG. No differences were observed between the groups in complication rates (5.0 vs. 5.1%, p=0.93). Percent of total weight loss was lower following one-stage than two-stage procedure at both 6 months (19.3±9.3 vs. 21.5±8.1%; p=0.02) and 1 year postoperative (24.9±10.4 vs. 27.8±9.9%; p=0.02). No difference was observed in the percent excess weight loss (51 vs. 56%; p=0.34 and 66 vs. 72%; p=0.38, at 6 months and 12 months postoperative, respectively). In a regression analysis, percent excess weight loss was greater in the two-stage procedure (p=0.02), with no difference in the complication rates (p=0.98).
Conclusion
Single-step LSG had a similar safety profile as two-stage LSG following a failed LAGB. Better weight loss was seen following two-stage LSG. Further prospective studies should investigate long-term follow-up after one- and two-stage procedure.
