Partial colectomy involves removing part of the colon and may also be called subtotal colectomy.
During a partial colectomy, a surgeon removes the diseased portion of your colon and a small portion of surrounding healthy tissue.
The surgeons makes four ¼ inch incisions in the region of the damaged colon and will insert a tiny camera to the surgical site. This gives clear visualization of the surgical field and allows him to go in through the other ports to remove the section of the diseased or damaged colon. Once the damaged section is removed, the colon will be reattached to the rest of the digestive system. The surgery is performed under general anesthesia (completely asleep.)
