Efficacy of sleeve gastrectomy plus gastric remnant banding on weight reduction and remnant gastric dilatation: an animal experimental study / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy of sleeve gastrectomy plus gastric remnant banding on weight reduction and remnant gastric dilatation in SD rat model.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>The number of survival rats was 15 in the study group (15/20), 13 in the control group (13/20), and 10 in the blank control group (10/10). Postoperative body weight increased markedly in the blank control group, returned to the pre-operative level two weeks after operation in the control group, and four weeks after operation in the study group. Weight increase of the study group was significantly slower than that of the other two groups (P<0.01). Postoperative gastric dilation of the control group was more obvious as compared to the study group.</p><p><b>CONCLUSION</b>Sleeve gastrectomy plus gastric remnant banding is safe and effective because of the restriction of postoperative gastric dilation.</p>
