INTRAOPERATIVE COLONOSCOPY IN PATIENTS WITH COLO-RECTAL CARCINOMA

Multiple cancers were recognized on 8.3% (21/254) of the resected specimens from the patients with colorectal carcinoma. The advanced cancer was diagnosed by the routine preoperative examinations but the early cancer was hardly found prior to the operation, especially in cases with stenosis of the colon by the tumor. The lesions, which were overlooked preoperatively and diagnosed as carcinoma by the postoperative histologic examination, were frequently located in the oral side from the advanced cancer of the resected specimen. In addition, adenomatous polyps were found in patients with multiple colo-rectal cancers with two times higher incidence than in those having a single cancerous lesion. They were frequently located in the resected specimen orally from the malignant lesions.
On the basis of the above, the flexible fiberoptic colonoscope to the intraoperative environment was utilized in 24 patients with cola-rectal carcinoma to detect a small lesion which might be overlooked preoperatively. The technique resulted in 7 polypoid lesions detected in 5 cases, though an early cancer was not found so far. Intraoperative colonoscopy is beneficial in the colorectal cancer patient, especially in those with stenosis of the tract by the tumor.
