Abstract
We evaluated 54 patients who were diagnosed intraoperatively as having a strangulating obstruction of the small bowel. They were divided into two groups：the necrotic group (n=30); and the non-necrotic group (n=24). There was no difference in the sex ratio, average age, past history of abdominal open operation, insertion of small intestinal tube and WBC counts between the groups. There were, however, significant differences in CRP (P=0.009), shock before operation (P=0.01), fever (P=0.03) and ascites during the operation (P=0.03). Concerning the CT scan findings, a closed-loop obstruction was the only significant difference. When a strangulating obstruction of the small bowel is suspected, accompanied by symptoms of shock or fever, small intestinal necrosis may be possible. Based on the CT findings, closed-loop obstruction and ascites are effective in the diagnosis of intestinal necrosis.
