Surgery
Surgery for
diverticulitis involves removing the diseased part of
the colon. You may decide to have surgery for diverticulitis if you
have:
- A partially blocked colon or a narrow spot in
the colon (stricture).
- Repeated attacks of diverticulitis. Surgery
to remove the diseased part of the colon often is recommended if you have two
or more severe attacks.
- A high risk of complications (such as
people younger than age 40 who have had an attack of
diverticulitis).
- Repeated problems with bleeding from the
colon.
- An abnormal opening (fistula) that has formed between the
colon and an adjacent organ, most commonly the bladder, uterus, or
vagina.
- Signs of possible cancer that cannot be confirmed with
other tests.
Surgery for diverticulitis, in which the infected part of
the colon is removed, may be required if you have
complications, including:
- An infected pouch (diverticulum
) that has
ruptured into the abdominal cavity, especially if a pocket of infection (abscess) has formed. In some cases, an abscess can be
drained without surgery. (See the Other Treatment section of this
topic.) - An infection that has spread into the abdominal cavity
(peritonitis).
- A blocked colon (bowel
obstruction).
- Infection that has spread through the blood to other
parts of the body (sepsis).
- Severe bleeding that
does not stop with treatment given through an angiogram or colonoscopy.
Overall, fewer than 6 out of 100 people with diverticulitis
need surgery.3
Surgical treatment
involves removing the diseased part of the large intestine (partial colectomy)
and reconnecting the remaining parts. Depending on the severity and nature of
the symptoms, more than one surgery may be needed to correct the problem. When
multiple surgeries are needed, the person usually has a
colostomy during the time between surgeries. A
colostomy is a surgical procedure in which the upper part of the intestine is
sewn to an opening made in the skin of the abdomen. Stool passes out of the
body at this opening and into a disposable bag. The colostomy is usually
removed and the intestine reconnected at a later time.
Surgery Choices
Surgical treatment of diverticulitis, called
partial colectomy, involves the removal of the
diseased part of the large intestine.
What To Think About
People who have mild, brief
attacks and who are willing to try long-term dietary changes may be able to
avoid surgery. See the Prevention section of this topic for more information on
diet.
If you have multiple attacks of diverticulitis, surgery may
be appropriate.
The survival rate is 99% for nonurgent (elective)
surgery for diverticulitis.4 An emergency surgery has
more risks.
