A colostomy creates an opening from the large intestine through the wall of the belly. An ileostomy creates an opening from the small intestine through the wall of the belly. It may be temporary or permanent.
The opening for both is called a stoma. It allows waste to pass from the intestines to a bag outside the body.

The intestines create a path for food to be digested and passed out of the body. A colostomy or ileostomy may be needed if the path through the intestine is interrupted. The interruption may be due to injury or illness of the intestine such as:

General anesthesia will be used. It will block pain and keep you asleep through the procedure.
The exact steps will differ based on the specific reason for the surgery. Other work may need to be done before the ostomy is created. The surgery may be:
An opening will be made through the muscle and skin of the abdominal wall.
If a section of the intestine has been removed, part of the remaining intestine will be pulled through the opening. The intestine end is secured outside the opening with sutures. This creates the stoma.
If the intestine remains intact, a section of the intestine will be placed next to the opening in the abdominal wall. Incisions will be made in the intestine wall to create an opening. The open area of the intestine will be pulled through the opening of the abdominal wall. The inner lying tissue of the intestine will create the stoma.
In both options the stoma is secured with sutures.
After the operation, you will be taken to the recovery room for observation.
How long the procedure takes depends on the reason you need to have the ostomy.
