Abstract

Background

Our objective was to observe the therapeutic effects of sleeve gastrectomy plus gastric remnant banding on weight reduction and gastric dilatation in an 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 study 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 surviving rats was 15 in the study group (15/20), 13 in the study control group (13/20), and 10 in the blank control group (10/10). Postoperative body weight increased markedly in the blank control group and returned to the preoperative level 2 weeks after operation in the study control group and 4 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 study control group was more significant than that of the study group.

Conclusion

Sleeve gastrectomy plus gastric remnant banding is safe and the therapeutic outcome is better in that it restricts postoperative gastric dilation and helps reduce long-term body weight more effectively.
