Comparison of sleeve gastrectomy and Roux-en-Y gastric bypass after failure of gastric banding: a two-center study with a propensity score-matched analysis

Abstract : Background Few studies on series comparing sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) after failure of gastric banding (GB) are available. The objective of this study was to compare the short- and medium-term outcomes of SG and RYGB after GB. Materials and methods Between January 2006 and December 2017, patients undergoing SG (n = 186) or RYGB (n = 107) for failure of primary GB were included in this two-center study. Propensity-score matching was performed based on preoperative factors with a 2:1 ratio. Primary endpoint was the weight loss at 2 years between the SG and RYGB groups. Secondary endpoints were overall mortality and morbidity, reoperation, correction of comorbidities and the rate of adverse events at 2 years follow-up. Results In our propensity score matching analysis, operative time was significantly less in the SG group (95 min vs. 179 min;p < 0.001). Post-operative complications were lower in the SG group (9.5% vs. 35.4%;p = 0.003). At 2 years follow-up, the mean EWL was similar as same as comorbidities. There was a significant difference in favor of SG concerning the rate of adverse events at 2 years follow-up (p < 0.001). Conclusion Revision of GB by SG or RYGB is feasible, with a higher rate of early post-operative complications for RYGB. Weight loss at 2 years follow-up is similar; however, RYGB appears to result in a higher rate of adverse events than SG.
