Seven sustained trauma in traffic accidents and the other one was injury at skiing.<BR>These cases were classified into three types according to clinicopathological findings. The first, perforated type, showed single to multiple perforations mainly located at and near the mesenteric side. Perforations were considered to have been induced by dirert crush injury against spine, or increased intraluminal pressure of a closed loops. The second, intra-abdominal bleeding type, showed mesenterial injury with intraabdominal bleeding clinically and mucosal necrosis with hemorrhage histologically hese mucosal changes were considered to have been caused by secondary ischemic changes due to mesenterial injury. The third, chronic stricture type, showed delayed posetraumatic stricture of the intestine. Shallow ulcer scars, fibromuscflosis in the submucosa, as well as siderophage reaction and hypertrophic change of muscle layer in the subserosa were evient, microscopically.
