袖带胃减容加残胃捆扎术的减重疗效和残胃扩张的实验研究

目的通过建立袖带胃减容加残胃捆扎手术实验动物模型，观察减重效果及残胃扩张情况。方法20只SD大鼠接受袖带胃减容加残胃捆扎手术（实验组），另20只SD大鼠接受袖带胃减容手术（实验对照组），10只SD大鼠接受剖腹探查手术（空白对照组）；在术前、术后第1天和术后16周内每隔2周测量体质量。结果实验组15只SD大鼠存活，实验对照组13只SD大鼠存活．空白对照组10只SD大鼠均存活。空白对照组术后体重增长明显；实验对照组术后2周体重恢复至术前水平：实验组在术后4周恢复至术前水平，其体质量增长明显较前两组慢（P〈0．01）。与实验组相比，实验对照组术后胃扩张明显。结论袖带胃减容加残胃捆扎手术限制了术后胃的扩张．减重效果好．且安全可行。

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. Results 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. Conclusion Sleeve gastrectomy plus gastric remnant banding is safe and effective because of the restriction of postoperative gastric dilation.
