ObjectiveTo explore the feasibility and curative effect of gastric pacing on postsurgical gastroparesis. MethodsThe indexes of gastric dynamic of applying gastric pacing to the experimental animal model of acute postsurgical gastroparesis was compared with that of injecting erythromycin (1 mg/kg).ResultsThe pressure of gastric antrum and the pressure gradient between gastric antrum and duodenum were respectively higher than basic pressure in the two experimental groups (P＜0.01); Except duodenal pressure, the indexs of gastric dynamic of pacing group were higher than that of erythromycin group (P＜0.05). The gastric emptying rate of pacing group 〔(66.37±7.21)%〕 was higher than erythromycin group 〔(49.92±9.27)%， (P＜0.01)〕. ConclusionHigherfrequency gastric pacing can improve the indexes of gastric dynamic and be applied to treat postsurgical gastroparesis, its effect may be better than erythromycin.
