Laparoscopic sleeve gastrectomy combined with single-anastomosis duodenal-jejunal bypass in the treatment of type 2 diabetes mellitus of patients with body mass index higher than 27.5 kg/m2 but lower than 32.5 kg/m2.

Abstract

This study aimed to introduce this surgical technique laparoscopic sleeve gastrectomy combined with single-anastomosis duodenal-jejunal bypass (LDJB-LSG), and to confirm this new surgical technique was safe in the treatment of type 2 diabetes mellitus (T2DM) of patients with body mass index (BMI) higher than 27.5 kg/m2 but lower than 32.5 kg/m2.A total of 34 T2DM patients with (BMI) higher than 27.5 kg/m2 but lower than 32.5 kg/m2 were admitted to our department between January 2014 and October 2016, of whom 25 received laparoscopic gastric bypass surgery (LRYGB) and 9 received LDJB-LSG. The efficacy and safety were compared between the 2 groups.None in both groups died and had severe postoperative complications. All the surgeries were performed by laparoscopy, and none received switching to open surgery. Patients received regular follow-up after surgery and none were lost to follow-up.Our study indicates LDJB-LSG is similar to LRYGB in the improvements of the body weight, blood glucose, insulin resistance, islet β cell function, blood lipid profile and serum uric acid, and thus LDJB-LSG is applicable in T2DM patients with 27.5 kg/m2 ≤ BMI ≤ 32.5 kg/m2 and risk for gastric cancer. However, long-term therapeutic effects need to be evaluated by studies with multicenter, large sample size, and long-term follow-ups.
