39 名患者在切除原发性直肠 [23] 或直肠乙状结肠癌 [16] 之前接受了计算机断层扫描 (CT) 检查。 II期[仅肠壁增厚（大于0.5cm）]3例，IIIa期12例（肠壁增厚，侵犯邻近组织、肌肉或器官，但未延伸至盆腔侧壁），IIIb期（延伸至盆腔侧壁）18例，IV期6例（盆腔肿瘤和远处转移），I期（管腔内肿块）无患者 不加厚壁）。 CT 检测出全部 39 例直肠或直肠乙状结肠肿瘤（敏感性 = 100%），总体分期准确度为 92%。这些结果表明 CT 在原发性直肠和直肠乙状结肠肿瘤的检测和分期方面是有用且准确的。
Thirty-nine patients were examined by computed tomography (CT) prior to resection of primary rectal [23] or rectosigmoid carcinoma [16]. There were 3 patients in Stage II [thickened bowel (greater than 0.5 cm) alone], 12 in Stage IIIa (thickened bowel wall and invasion of adjacent tissue, muscles, or organs, but no extension to the pelvic side walls), 18 in Stage IIIb (extension to the pelvic side walls), 6 in Stage IV (pelvic tumor and distant metastases), and none in Stage I (intraluminal mass without wall thickening). CT detected all 39 rectal or rectosigmoid tumors (sensitivity = 100%) and had an overall staging accuracy of 92%. These results show that CT is useful and accurate in detecting and staging primary rectal and rectosigmoid tumors.
