Purpose : To evaluate the usefulness of CT for assessing the location and cause of pathologic gastrointestinal perforationMaterials and Methods : A retrospective analysis of abdominal CT was performed in 27 perforations of 26 patients with underlying gastrointestinal pathology. Fifreen benign and 12 malignant perforations consisted of five gastric cancers, one gastric ulcer, ten duodenal bulb ulcers, one radiation colitis and six colon cancers.CT scans were evaluated for 1) diagnosis of bowel perforation, 2) assessment of the cause and site of perforation, and , in particular, differentiation between benignancy and malignancy, and 3) complications and their extent.Results : CT easily detected varying amounts of free air or fluid collection, and infiltration or abscess formation adjacent to the main lesion, and the diagnosis of gastrointestinal perforatiom was therefore easy. In 11 of the 12 malignancies (92%), primaty tumor was diagnosed, but detection of the site of perforation was possible in only seven cases(7/12, 58%). The 15 benign lesions revealed nonspecific CT finding, and the perforation site could be presumed in six (6/15, 40%). In one case of Crohn's disease, the primary cause was visualized.Among six colonic cancers, four pericolic abscesses and two fistulas to adjacent organs were found, but there was no evidence of diffuse peritonitis.Conclusion : CT was helpful tolead to optimal treatment of pathologic gastrointestinal On CT the detectability of perforation, primary benign or malignant lesion, perforation site and extent of complication was high, and this modality was therefore a useful indicator of the optimal treatment for athologic gastrointestinal perforations.
