Crohn’s disease is an inflammatory bowel disease that damages the small and large intestines. A doctor may recommend Crohn’s disease surgery for a person with severe symptoms if other treatments are not helping.

Surgery does not cure Crohn’s disease, but it can reduce complications associated with the disease.

According to the United States’ National Institute of Diabetes and Digestive and Kidney Diseases, an estimated 60 percent of people with Crohn’s disease have surgery within 20 years of their diagnosis.

When is surgery an option for Crohn’s disease?

Doctors typically prescribe medications and recommend dietary changes to help keep Crohn’s disease flare-ups and symptoms to a minimum.

However, a person can still experience inflammation and other complications, especially if the disease is severe.

Surgery is invasive, so doctors will not usually recommend it unless absolutely necessary. Examples of these instances include if a person has:

  • an abscess or pocket of infection
  • a fistula
  • intestinal bleeding
  • intestinal obstructions
  • irreversible intestinal damage
  • symptoms not reduced by other treatments

Doctors may also use surgery in emergency situations, such as a bowel obstruction. Researchers in one study estimate that 6 to 16 percent of people with Crohn’s who present with acute symptoms require surgery.

Surgery types

There are several types of surgery that a doctor may recommend for Crohn’s disease. These include:

What to expect

Doctors perform Crohn’s disease surgery while a person is under general anesthesia. This means the patient is asleep and will not feel pain during the procedure.

Immediately after the surgery, a person will experience some pain and discomfort.

Sometimes, they will receive nutritional support intravenously, such as total parenteral nutrition or TPN. This is because the bowel needs time to rest and heal after surgery.

After the recovery time, a person will often begin eating again with a liquid or low-fiber diet that is easy to digest. A doctor, dietitian, or both will help the individual make further changes in their diet that may be necessary.


Researchers estimate that one-third of people undergoing Crohn’s disease surgery will experience post-operative complications.

A person is at higher risk of complications if they are having emergency surgery, because the body may already be affected by infection, dehydration, low blood counts, or other factors.

More severe complications include:

  • Anastomotic leak: The area where doctors sew the two portions of intestine together is known as the anastomosis. This area is at risk for leakage of bowel contents if the pieces of intestine do not fuse together correctly. This can cause severe infection and illness.
  • Surgical site infection: An infection in the gastrointestinal tract or abdomen can cause pain, swelling, fever, and many other symptoms.
  • Bleeding: Bleeding, especially at the anastomosis, is another possible complication of Crohn’s disease surgery. Low blood counts can impair the body’s ability to heal, and can sometimes be life-threatening. A person may require blood transfusions if their blood counts are too low.

Other complications associated with Crohn’s disease surgery include:

If a person with Crohn’s disease is taking immunomodulators or other medications that can impair wound healing, recovery may be more challenging.

For this reason, doctors often recommend reducing these medications before surgery to minimize the risks.

The length of recovery depends upon the surgery type and the person’s overall health before surgery.

The more invasive and lengthy the surgery, the longer the healing time tends to be. A doctor should discuss these considerations, as a person will likely need to make arrangements with work or school and limit their physical activity while they recover.

Surgery for Crohn’s disease does not cure this condition. Instead, it helps a person manage their symptoms and can help prevent potentially life-threatening side effects.

A person will likely experience new areas of inflammation where they did not previously.


Crohn’s disease surgery is one way to treat damage from the disease and reduce risks for harmful effects.

A doctor will typically recommend surgery only when it is absolutely necessary. While surgery does not cure Crohn’s disease, it can help reduce the risks of complications, such as severe infections.
