[Impact of techniques for gastrointestinal tract reconstruction following gastrectomy on pancreatic β-cell function in patients with type 2 diabetes mellitus].

Objective: To evaluate the impact of different techniques for gastrointestinal tract reconstruction on postoperative pancreatic β-cell function in patients with type 2 diabetes mellitus (T2DM).

Methods: Twenty-three patients with gastric cancer and T2DM were studied. Techniques for reconstruction included Billroth I (n=13) and bypass procedures(Billroth II n=4 and Roux-en-Y anastomosis n=6).

[Efficacy of sleeve gastrectomy plus gastric remnant banding on weight reduction and remnant gastric dilatation: an animal experimental study].

Objective: To investigate the efficacy of sleeve gastrectomy plus gastric remnant banding on weight reduction and remnant gastric dilatation in SD rat model.

Methods: Sleeve gastrectomy plus gastric remnant banding was performed in 20 male SD rats as the study group; sleeve gastrectomy was performed in 20 SD male rats as the control group, and laparotomy was performed in 10 SD male rats as the blank control group. Body weight was measured before the experiment, at day 1 and at 2-week intervals within 16 weeks after operation.
