OBJECTIVE:The aim of the present study was to assess the presence of duodenal erosion and its clinical characteristics on endoscopy in patients with portal hypertension who had undergone endoscopic injection sclerotherapy and/or endoscopic variceal ligation for esophagogastric varices.METHODS:The subjects were 440 patients with portal hypertension, 450 with chronic hepatitis as a related control group, and 450 who underwent upper endoscopic examination as part of their routine physical examination as the controls. The underlying hepatic disease, hepatic function, and endoscopic findings of duodenal erosion among the patients with portal hypertension were studied.RESULTS:Duodenal erosion was found in 68 patients with portal hypertension (68 of 440, 15.5%), four patients with chronic hepatitis (four of 450, 0.9%), and two controls (two of 450, 0.4%). The incidence of duodenal erosion among the patients with portal hypertension was significantly higher than that in the other two groups (p < 0.01, p < 0.01, respectively). The lesions commonly observed in duodenitis are speckle erosions mainly located in the duodenal bulb. However, the most frequently seen form of duodenal erosion among the patients with portal hypertension extended from the superior portion to the descending portion, and tended to show a circular alignment along the Kerckring’s folds. The patients with portal hypertension with reduced hepatic reserve capacity had more severe duodenal erosion. Endoscopic ultrasonography revealed thickening of the duodenal wall and proliferation of vascular structures within and around the wall. The histological findings of the duodenal erosion included edema and vascular dilation in the mucosal and submucosal layers.CONCLUSIONS:The location of duodenal erosion in patients with portal hypertension differs from that in patients with ordinary duodenitis. Duodenal erosion in patients with portal hypertension is considered to be one of the lesions of portal hypertensive duodenopathy.
