Colostomy
| Normal anatomy |
|
The colon or the large intestine connects the small intestines to
the rectum. |
| Indication |
|
A colostomy is done when the lower large intestine, rectum, or anus
is unable to function normally or needs rest from normal functions.
Intestinal obstruction with associated inflammation, as in
diverticulitis, is a common indication for colostomy. |
| Procedure, part1 |
|
A colostomy creates an opening on the abdomen (stoma) for the
drainage of stool (feces) from the large intestine (colon).
Colostomies are usually performed after the diseased colon has been
removed.
Colostomies may be temporary or permanent. While the patient is
deep asleep and pain-free (general anesthesia), an incision is made
in the abdomen. The diseased colon is removed.
|
| Procedure, part 2 |
|
The proximal end of the healthy colon is then brought out to the
skin of the abdominal wall, where it is sutured in place. An
adhesive drainage bag (stoma appliance) is placed around the
opening. The abdominal incision is then closed. |
| Aftercare |
|
In more than 90% of the cases, the surgery is successful.
The patient may have crampy pain after surgery as the anus
tightens and relaxes. Medications to relieve pain may be used.
Avoid any straining during bowel movement or urination. Soaking in
a warm bath can bring additional comfort. Depending on the disease
process being treated, colostomies can be removed and the colon
reconnected in a second operation within weeks to months after the
first operation.
