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.
