Small bowel resection

Also known as: Bowel resection

Resection is another name for any operation that removes tissue or part of an organ. Bowel resection, also called partial colectomy, for colorectal cancer removes the tumor and part of the colon or rectum on either side.

The goal of bowel resection is to take out the part of the colon or rectum where the cancer is. Nearby lymph nodes are taken out and tested for cancer. Then healthy parts of the colon or rectum are sewn back together. Bowel resection is done either by opening the abdomen (open resection), or by laparoscopy.
