Surgical formation of an artificial anus by making an opening from the colon through the abdominal wall.

It may be done to decompress an obstructed colon, to allow excretion when part of the colon must be removed, or to permit healing of the colon. Colostomy may be temporary or permanent. A sigmoid colostomy, the most common type of permanent colostomy, requires no appliances (though a light pouch is sometimes worn for reassurance) and allows a normal life except for the route of fecal excretion. See also ostomy.

      the surgical formation of an artificial anus by making an opening from the colon through the abdominal wall. A colostomy may be performed in order to decompress an obstructed colon; to divert the fecal stream after traumatic injury or when resectioning an inflammatory, obstructive, or perforated lesion; to replace the anus as the distal opening of the gastrointestinal tract when the distal colon or rectum is removed; and to promote internal healing. Colostomies may be temporary or permanent. A sigmoid colostomy, which is the most common type of permanent colostomy, requires no appliances (although a light pouch is sometimes worn for reassurance) and allows an individual to lead a life that is in every way normal except for the route of fecal evacuation.
