Local excision for selected colorectal carcinomas.

Abstract

In summary, local excision is a useful tool in the management of selected colorectal carcinomas. The advent of the fibreoptic colonoscope has revised the concept of local excision when dealing with carcinoma-containing polyps of the colon. The clinician now has the means of locally excising certain carcinomas which would have required laparotomy in the not so distant past. In dealing with carcinoma of the rectum, local excision is not advocated for all rectal carcinomas. In fact, when the previously discussed tumour related factors are considered, local excision should be the ultimate procedure in less than 5% of operations performed for rectal carcinomas. However, when appropriately used, local excision provides a less morbid alternative to more radical procedures without compromising patient survival rates or local recurrence rates.
