Surgery
Surgery is rarely done for
Crohn's disease and it is not a cure. When surgery is
needed, as little of the intestines as possible is removed to preserve normal
function. The disease tends to return in areas that were previously not
affected, and you may need surgery again.
Surgery may be needed for Crohn's disease if no medicine can
control your symptoms, you have serious side effects from medicines, your
symptoms can be controlled only with long-term use of corticosteroids, or you
develop complications such as fistulas, abscesses, or bowel
obstructions.
Surgery may be needed when you have:
- Bowel blockage (obstruction).
- Abscesses or tears (fissures) in the anal area or when
abnormal connections (fistulas) form between two parts of the
intestine or between the intestine and other internal organs.
- Holes
(perforations) in the large intestine.
- Cancer or precancerous
tissue.
- Severe disease that does not respond to other
treatment.
- Severe bleeding that requires ongoing blood
transfusions.
Surgery Choices
Surgery is not usually done for Crohn's disease. If you do have
surgery, it will most likely be one of the following:
- Resection: The diseased portion of the
intestines is removed, and the healthy ends of the intestine are reattached.
Resection surgery does not cure Crohn's disease, which often comes back near
the site of surgery.
- Proctocolectomy and ileostomy: The
surgeon removes the
large
intestine and rectum
, leaving the lower end of the small intestine (the
ileum). The anus is sewn closed, and a small opening called a stoma is made in
the skin of the lower abdomen. The ileum is connected to the stoma, creating an
opening to the outside of the body, where stool empties into a small plastic
pouch called an ostomy bag that is applied to the skin around the stoma. - Strictureplasty: The surgeon makes a lengthwise cut in the
intestine and then sews the opening together in the opposite direction. This
makes the intestine wider and helps with obstruction of the bowels. This is
sometimes done at the same time as resection, or when a person has had
resection in the past. Strictureplasty is used when the doctor is trying to
save as much of the intestines as possible.
Another procedure that may be done is balloon dilation. This is
not a surgery. The doctor runs a scope through your intestines from your anus.
The scope is a long, thin tube that has a video camera on the end. Next, the
doctor uses the endoscope to thread an uninflated balloon across the stricture
(the narrowed part of the intestine). When the balloon is inflated, it makes
that part of the intestine wider. The balloon is deflated and then removed.
Balloon dilation is a new technique and not as much is known about its
long-term success compared to the surgical procedures listed above. Balloon
dilation might be done if you want to put off a more complicated surgery for a
while or if you have had surgery before and the doctor wants to save as much of
the intestines as possible.
What To Think About
These surgeries can be done on children. Surgery can improve a
child's well-being and quality of life and restore normal growth and sexual
development.
In rare cases,
intestinal transplant is used to treat Crohn's
disease. In this complex procedure, the small intestine is removed and replaced
with the small intestine of a person who has recently died and donated his or
her organs.
In very rare cases, when the risk of other surgery is high,
bypass surgery may be done to preserve the bowel. In this procedure, the
intestine is cut above the diseased area and reconnected to a healthy section
below the diseased area. The diseased part of the intestine remains but is no
longer used. This surgery is not done often because the diseased loop remains
and may cause problems later.
