Colonoscopy: an essential monitoring technique after resection of colorectal cancer
Abstract:
A pilot study was undertaken to determine the usefulness of colonoscopy in the postoperative follow-up of patients with colorectal cancer. Of 56 patients, 9 (17 percent) had positive intraluminal examinations, including one recurrent cancer and three large polyps (greater than 1 cm) despite normal barium enema films. Twenty percent had negative colonoscopic findings which ruled out suspicious lesions on roentgenograms. More than one third had alterations in therapy as a result of colonoscopic examination. Colonoscopy is a useful and fruitful diagnostic aid in the follow-up of colon cancer. It should be used early in the postoperative period and added at rational intervals in long-term surveillance. It appears to complement other accepted methods of detecting recurrence.
