ABSTRACT
The incidence of misdiagnosis of colon injury is higher during the war because of limited conditions. The diagnosis of colon injury is easy to be neglected in the patients with closed wound of abdomen of penetrating wound of abdomen complicated by other trauma, the patients with complication of severe shock or craniocerebral injury causing lose of consciousness, and the colon injury patients without obvious sign of peritonitis or wound in abdomen. Complete abdominal examination with care and serious explorative laparotomy are the key to avoid misdiagnosis of colon injury. Owing to the fact that the wounded can not be observed carefully during the war, the indication of explorative laparotomy may not be so strict. The operation should be done under good light and extensive exposure. Shock must be prevented and corrected during exploration. The hepatic flexure, splenic flexure and fixing part of the colon should be examined carefully. Retropentoneal hematoma must be incised to explore if necessary. Small hematoma in the wall of colon also should be explored and managed in order to avoid delayed perforation of colon.
