Abstract

Abstract: Purpose: Sleeve gastrectomy (LSG) and mini gastric bypass (LMGB) was considered as emerging procedures but are now considered for many authors as an alternative of the Roux-Y gastric bypass because of similar percentages of weight loss and better postoperative morbidity profiles. However, studies comparing LSG and LMGB are scarce. Materials and methods: From January 2010 to July 2014, 262 and 161 patients underwent LSG or LMGB in two centre of bariatric surgery, respectively. At one year, rate of follow-up was 88.4%. Main outcome was % of Total Weight Loss (%TWL) at one year. Propensity score matching and multivariable analyses were used to compensate for differences in some baseline characteristics. Results: After matching LSG (N = 136) and LMGB (N = 136) groups did not differ for initial BMI (kg/m 2 ) (43.4 ± 6.5 vs. 42.8 ± 5.0; P = 0.34), % of female patients (91.9% vs. 93.4%; P = 0.64), age (years) (41.2 ± 12.3 vs. 41.2 ± 11.3; P = 0.99) and diabetes (15.4% vs. 19.9%; P = 0.34). At one year, %TWL, change in BMI and rate of stenosis were higher for LMGB group, respectively: 38.2 ± 8.4 vs. 34.3 ± 8.4 (P < 0.0001); −16.5 ± 4.6 vs. −14.9 ± 4.4 (P = 0.005) and 16.9% vs. 0% (P < 0.0001). In multivariate analyses (β coefficient), LMGB was a positive independent factor of %TWL (2.8; P = 0.008). Conclusion: LMGB seems to have better weight loss at one year compared to LSG with higher gastric complications. Further long term studies are needed. Highlights: Sleeve gastrectomy and mini gastric bypass are procedures challenging Roux-Y gastric bypass. Mini gastric bypass provides better weight loss at one year. Mini gastric bypass had higher gastric complications at one year.
