title: [Contribution of radiology to the postoperative after care of patients with colorectal tumors].
abstract: 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.
