title: Local recurrence after sphincter-saving resection for rectal and rectosigmoid carcinoma. Value of various diagnostic methods.
abstract: The authors reviewed 51 cases of local recurrence after sphincter-saving resection for rectal and rectosigmoid carcinoma to assess the sensitivity of current diagnostic procedures. A combination of follow-up serum CEA levels and rectoscopy was found to be most efficient during the first two years after surgery in terms of the time, frequency, and location of the recurrence as well as the cost-benefit ratio. On the other hand, almost all recurrent lesions developed extraluminally, infiltrating the suture line secondarily; moreover, one fourth extended outside the bowel wall. Thus in addition to endoscopy, CT is useful as a means of defining the entire mass at the anastomosis as well as detecting pericolic recurrence and is essential if repeat resection is contemplated.
