The prognosis of local recurrences after surgery for colorectal cancer is better than in recurrences of many other tumor sites. Since in most cases secondary tumor growth takes place as local recurrence and distant metastases are infrequent, there is a good chance of detecting the recurrence early in a curable state. This offers good conditions for a radical second operation. Following excision of tumors, double-contrast enema permits a very detailed assessment of the anastomosis, allowing detection of small local recurrences and recognition of postoperative changes or sequelae of delayed healing at the site of the anastomosis. Following amputation of the rectum, computed tomography permits better control of the presacral space than other conventional radiodiagnostic procedures. In both situations, however, integration of both methods is necessary in a consequent time schedule of clinical follow-up with suitable intervals.
结直肠癌手术后局部复发的预后比许多其他肿瘤部位的复发要好。由于在大多数情况下，继发性肿瘤生长以局部复发的形式出现，远处转移并不常见，因此很有可能在可治愈状态下早期发现复发。这为进行根治性二次手术提供了良好条件。肿瘤切除后，双重对比灌肠可以非常详细地评估吻合口，能够检测到小的局部复发，并识别吻合口部位的术后变化或延迟愈合的后遗症。直肠切除术后，计算机断层扫描比其他传统放射诊断方法能更好地控制骶前间隙。然而，在这两种情况下，都需要在适当的时间间隔内将这两种方法整合到临床随访的后续时间表中。
