Abstract

Operative time was significantly less for sleeve gastrectomy (SG) at 95 minutes compared to Roux-en-Y gastric bypass (RYGB) at 179 minutes.

Post-operative complications were lower in the SG group, occurring in 9.5% of patients compared to 35.4% in the RYGB group.
At 2 years follow-up, mean excess weight loss (EWL) was similar between SG and RYGB groups.
Comorbidity correction rates were comparable between the two surgical approaches.
A significant difference in favor of SG was observed regarding the rate of adverse events at 2 years follow-up.

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.
