ABSTRACT

Objective To compare laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy for the treatment of obese patients with type 2 diabetes mellitus.Methods A retrospective analysis of T2DM patients with LRYGB (28 cases) and LSG (35 cases) was enrolled from Jan 2010 to Jun 2013.Results The indicator such as BMI,fasting glucose,fasting insulin,HbA1c,and insulin resistance were significantly lower in 1 year,3 years and 5 years after operation [LRYGB group(37.3 ±3.7) kg/m2 to (32.3 ± 3.4) kg/m2 to (28.8 ± 3.0) kg/m2 to (25.5 ± 2.8) kg/m2,t =13.670,15.499,21.710,P=0.000,0.000,0.000;(8.2 ± 1.8) mmol/L to (6.0 ± 1.3) mmol/L to (5.2 ±0.9) mmol/L to (4.7±0.5) mmol/L,t =6.664,8.723,10.282,P=0.000,0.000,0.000;(32.2±17.0) μ IU/ml to (16.1 ± 12.1) μIU/ml to (8.6 ±5.2) μ IU/ml to (5.2 ±2.8) μIU/ml,t =7.453,8.218,8.687,P =0.000,0.000,0.000;(7.4％ ±0.6％) to (6.2％ ±0.7％) to (5.7％ ±0.7％) to (5.1％ ±0.6％),t =11.362,18.771,21.186,P=0.000,0.000,0.000;(12.0±7.3) to (4.6±4.3) to (2.1 ±1.7) to (1.1 ±0.7),t =6.455,7.667,8.050,P=0.000,0.000,0.000;LSG group(39.2±5.2) kg/m2 to (34.1 ±4.5) kg/m2to (29.3±4.0) kg/m2to (25.1 ±2.3) kg/m2,t=11.676,13.680,19.161,P=0.000,0.000,0.000;(8.0±2.9) mmol/L to (5.8±1.5) mmol/L to (5.1 ±0.9) mmol/L to (4.6 ±0.5) mmoL/L,t=5.467,6.921,7.741,P=0.000,0.000,0.000;(29.1 ±25.2) μIU/ml to (16.4±10.6) μ IU/ml to (8.8±5.5) μ IU/ml to (5.5 ±2.0) μIU/ml,t =3.512,5.232,5.702,P=0.001,0.000,0.000;(7.7％ ±1.3％) to (6.3％ ±0.6％) to (5.8％ ±0.6％) to (5.2％ ±0.6％),t=8.001,10.106,11.922,P =0.000,0.000,0.000;(9.8 ±9.6) to (3.9 ±2.2) to (1.9 ±1.0) to (1.1 ± 0.4),t =3.733,4.972,5.404,P =0.001,0.000,0.000].There was no significant difference between the two groups in 1 year,3 year and 5 year post-operation (DM remission71％ to 69％,89％ to 80％,93％ to 89％) (P ＞ 0.05).Conclusion LRYGB and LSG have the same long-term efficacy for T2DM patients.
