Laparoscopic sleeve gastrectomy versus laparoscopic mini gastric bypass: One year outcomes.

Abstract

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.
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.
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).
LMGB seems to have better weight loss at one year compared to LSG with higher gastric complications. Further long term studies are needed.
