Comparative study between effect of sleeve gastrectomy and mini-gastric bypass on type 2 diabetes mellitus

Abstract

ObjectiveComparative study between the effect of LSG and LMGB on patients with type 2 DM and BMI ≥ 35 kg/m2. Study designA prospective comparative study which included 40 obese patients with type 2 DM(20 patients were operated for laparoscopic sleeve gastrectomy (LSG) and 20 patients for laparoscopic mini-gastric bypass (LMGB)), with mean age at LSG group 42.95 ± 7.63 with range of 31–59 years, at LMGB group was 42.9 ± 6.17 with range of 34–58 years. ResultsIn SG cases; complete remission occurred in 11 patients with percentage of 55% and failure of remission occurred in 9 patients with percentage of 45%. No cases developed partial remission in SG cases. In MGB cases; 15 developed diabetic remission with percentage of 75% (11 (55%) patients developed complete remission, 4 (20%) patients developed partial remission). Failure of remission occurs in 5 patients in MGB cases with percentage of 25%. ConclusionBased on our results, LSG and LMGB are efficient operations for reducing weight in morbidly obese patients and also in diabetic control in T2DM. LMGB might be superior to LSG in %EWL and T2DM remission after 1.5 year follow up.
