Objective To evaluate the effect of de-splanchnic circulation of the stomach ( DSCS) on ultramicrostructure of gastric mucosa and submucosal microcirculation in prehepatic portal hypertensive canine models. Methods Twelve prehepatic portal hypertensive canine models were established by half constriction and silk line chronic embolization of the portal vein. The esophageal varices and collateral circulation were observed by venography after 4 weeks. Dogs with established model were divided into pericardial devascularization group and DSCS group randomly. Esophageal variceal pressure ( VP) was meas-ured when the abdoman was open immediately before the
