An ostomy procedure is an overarching term used to describe the surgery performed to reroute the contents of the intestinal tract or urinary system when disrupted by disease or injury. Colostomies, ileostomies, and urostomies are all forms of ostomy surgery, each referring to the part of the body affected. ‘Colostomy’ refers to the redirection of the colon or large intestine through a stoma in the abdomen into a colostomy bag.
