Small bowel resectionSmall intestine surgery; Bowel resection - small intestine; Resection of part of the small intestine; Enterectomy
Small bowel resection is surgery to remove a part of your small bowel. It is done when part of your small bowel is blocked or diseased.
The small bowel is also called the small intestine. Most digestion (breaking down and absorbing nutrients) of the food you eat takes place in the small intestine.
You will receive general anesthesia at the time of your surgery. This will keep you asleep and pain-free.
General anesthesia is treatment with certain medicines that puts you into a deep sleep so you do not feel pain during surgery. After you receive the...Read Article Now Book Mark Article
The surgery can be performed laparoscopically or with open surgery.
If you have laparoscopic surgery:
- The surgeon makes 3 to 5 small cuts (incisions) in your lower belly. A medical device called a laparoscope is inserted through one of the cuts. The scope is a thin, lighted tube with a camera on the end. It lets the surgeon see inside your belly. Other medical instruments are inserted through the other cuts.
- A cut of about 2 to 3 inches (5 to 7.6 centimeters) may also be made if your surgeon needs to put their hand inside your belly to feel the intestine or remove the diseased segment.
- Your belly is filled with a harmless gas to expand it. This makes it easy for the surgeon to see and work.
- The diseased part of your small intestine is located and removed.
If you have open surgery:
- The surgeon makes a cut of 6 to 8 inches (15.2 to 20.3 centimeters) in your mid-belly.
- The diseased part of your small intestine is located and removed.
In both kinds of surgery, the next steps are:
- If there is enough healthy small intestine left, the ends are stitched or stapled together. This is called an anastomosis. Most patients have this done.
- If there is not enough healthy small intestine to reconnect, your surgeon makes an opening called a stoma through the skin of your belly. The small intestine is attached to the outer wall of your belly. Stool will go through the stoma into a drainage bag outside your body. This is called an ileostomy. The ileostomy may be either short-term or permanent.
An ileostomy is used to move waste out of the body. This surgery is done when the colon or rectum is not working properly. The word "ileostomy" come...Read Article Now Book Mark Article
Small bowel resection usually takes 1 to 4 hours.
Why the Procedure Is Performed
Small bowel resection is used to treat:
- A blockage in the intestine caused by scar tissue or congenital (from birth) deformities
Blockage in the intestine
Intestinal obstruction is a partial or complete blockage of the bowel. The contents of the intestine cannot pass through it.Read Article Now Book Mark Article
- Bleeding, infection, or ulcers caused by inflammation of the small intestine from conditions such as Crohn disease
An ulcer is a crater-like sore on the skin or mucous membrane. Ulcers form when the top layers of skin or tissue have been removed. They can occur ...Read Article Now Book Mark Article

Risks for this surgery include:

- Wound breaking open
- Wound infection
Before the Procedure
Tell your surgeon or nurse what medicines you are taking, even drugs, supplements, or herbs you bought without a prescription.
Talk with your surgeon or nurse about how surgery will affect:
- Intimacy and sexuality
During the 2 weeks before your surgery:
- You may be asked to stop taking blood thinner drugs. These include aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), and others.
- Ask the surgeon which drugs you should still take on the day of your surgery.
- If you smoke, try to stop. Smoking increases the risk for problems such as slow healing. Ask your doctor or nurse for help quitting.
- Tell your surgeon right away if you have a cold, flu, fever, herpes breakout, or other illness before your surgery.
- You may be asked to go through a bowel preparation to clean your intestines of all stool. This may involve staying on a liquid diet for a few days and using laxatives.
The day before surgery:
- You may be asked to drink only clear liquids such as broth, clear juice, and water.
- Follow instructions about when to stop eating and drinking.
On the day of surgery:
- Take the drugs your surgeon told you to take with a small sip of water.
- Arrive at the hospital on time.
After the Procedure
You will be in the hospital for 3 to 7 days. You may have to stay longer if your surgery was an emergency operation.
You also may need to stay longer if a large amount of your small intestine was removed or you develop problems.
By the second or third day, you will most likely be able to drink clear liquids. Thicker fluids and then soft foods will be added as your bowel begins to work again.
If a large amount of your small intestine was removed, you may need to receive liquid nutrition through a vein (IV) for a period of time. A special IV will be placed in your neck or upper chest area to deliver nutrition.
After you go home, follow instructions on how to take care of yourself as you heal.
You had surgery to remove all or part of your small intestine (small bowel). You may also have had an ileostomy.Read Article Now Book Mark Article
Most people who have a small bowel resection recover fully. Even with an ileostomy, most people are able to do the activities they were doing before their surgery. This includes most sports, travel, gardening, hiking, and other outdoor activities, and most types of work.
If a large part of your small intestine was removed, you may have problems with loose stools and getting enough nutrients from the food you eat.
If you have a long-term (chronic) condition, such as cancer, Crohn disease or ulcerative colitis, you may need ongoing medical treatment.
