Colorectal Resection
The growth and part of the colon or rectum surrounding the tumor are
removed (resected) during surgery. In most cases the surgery can be done
in 1 to 3 hours and patients are usually in the hospital 3 to 5 days. The most
common types of colorectal resection are listed below.
Before
❒ Right Hemicolectomy

colon and the cecum are
removed. The colon is
reconnected to the small
intestine.
❒ Left Hemicolectomy
Part or all of the descending
colon is removed. The
transverse colon is then
reconnected to the rectum.
❒ Sigmoid Collectomy
Part or all of the sigmoid
