Abstract
Objective: To describe the radiographic findings and its anatomic distribution of colorectal tumor at double-contrast barium enema examination
Research design: Retrospective study
Method: Radiographic findings of double-contrast barium enema examination which had pathological-proven of 48 patients with colorectal tumor were reviewed and analyzed.
Result: There were 5 radiographic findings:1. Annular lesion 2. Polypoid Iesion 3. Complete obstruction 4. Coil-spring appearance and 5. Infiltrative nodular Iesion. Annular (41.6%) and polypoid Iesion(25%) were the most and the second common findings respectively. Patho-logical diagnosis of tumor was adenocarcinoma 40 cases (83.4%) and lymphoma 8 cases (16.6%) Tumors of the transverse colon, descending colon, sigmoid colon and rectum accounted for 28 cases (58.3%) while tumors of the ascending colon and cecum accounted for 20 cases (41.6%)
Conclusion: Annular or apple-core appearance is the most common radiographic findings of colorectal tumor and however incidence of right side colon cancer was increased, tumor was stilled predominantly localized in left side colon
Keywords: radiographic findings, colorectal tumor, barium enema
