[Efficacy of laparoscopic sleeve gastrectomy on morbidly obese patients with type 2 diabetes mellitus].

Objective: To evaluate the efficacy of laparoscopic sleeve gastrectomy(LSG) on improving glycemic control of morbidly obese patients with type 2 diabetes mellitus.

Methods: Prospective study of 30 type 2 diabetes mellitus(T2DM) patients with BMI > or = 35 undergone LSG was carried out. Pre- and post-operative clinical parameters associated with diabetes mellitus 6 months after operation were evaluated. Data collected included demographics, weight loss(BMI, EWL%), diabetes control (FPG, HbA1C) and ghrelin.

Results: Fasting plasma glucose and glycosylated hemoglobin concentration tests and clinical outcomes suggested LSG resulted in significant improvement or resolution of T2DM in all the 30 patients with CR 63%(19/30) and PR 37%(11/30).

Conclusions: LSG can lead to significant changes in controlling glycemia on morbidly obese patients with T2DM in 6 months. Long-term efficacy needs further follow-up.
