Transcatheter arterial embolization (TAE) has been conducted for therapy of patients with hepatocellular carcinoma with favorable results. Some complications with this procedure have been reported, but few gastroduodenal complications were previously reported. In order to clarify the effects of TAE on the gastroduodenal tract, endoscopic examinations of the upper gastrointestinal tract were performed 13 times in 8 patients before and after TAE. Three of them were subsequently found to have multiple gastric erosions with redness and ulcers, and multiple duodenal erosions were observed in one. In a case with acute gastric ulcers, autopsy revealed severe fibromusculosis in the submucosal layer of the antrum histologically, which suggested that both mucosa and submucosa in the stomach might be damaged by TAE. These changes of gastroduodenal mucosa were supposed to bedue to gastroduodenal infarction after TAE. In all cases esophageal varices were observed, but no paticular changes were found in the endoscopic findings after TAE.
