Colostomy / Ileostomy
by Cynthia M. Johnson, MA
An ostomy is a surgical procedure that connects an internal organ to the surface of the body. An artificial opening (called a stoma) is created to allow waste to exit the body and pass into an external bag.
The 2 types of ostomies discussed here include:
An ostomy may be temporary or permanent.
Reasons for Procedure TOP
The intestines create a path for food to be digested and passed out of the body. An 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:
A temporary ostomy may be done to allow the intestine to rest after surgery, trauma, or illness.
A permanent ostomy may be needed if:
Possible Complications TOP

What to Expect TOP
Prior to Procedure
Certain medications may cause complications during the procedure or recovery. These medications may need to be stopped up to one week before the procedure. Talk to your doctor before the procedure about all medications, herbs, and supplements you are taking.
General anesthesia will be used. It will block pain and keep you asleep through the procedure.
Description of the Procedure TOP
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.
