Small Bowel Resection
(Small Intestine Surgery; Ileum Surgery)
A small bowel resection is the removal of part of the small intestine. The small intestine includes the duodenum, jejunum, and ileum. The surgery can be done through an open incision or using smaller incisions using a laproscope.

Reasons for Procedure
This procedure may be done to treat the following:
- Intestinal blockage
- Bleeding, infection, ulcers, or holes in the small intestines
- Precancerous polyps
- Crohn disease
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
- Excessive bleeding
- Blockage of the intestine caused by scar tissue
- Hernia formation at the incision site
- Leakage from joining of intestinal edges
- Inability to get enough nutrients and vitamins if too much intestine needed to be removed
Factors that may increase the risk of complications include:
- Previous abdominal surgery
- Chronic illness
- Drug use
What to Expect
Prior to Procedure
Your doctor may do the following:
Leading up to your procedure:
- Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
- Your doctor may advise antibiotics.
- Your intestines should be cleaned out for the surgery. During the week before surgery, eat high-fiber foods and drink plenty of water. This will encourage bowel movements. Other cleansing methods may also be recommended, including enemas, laxatives, and a clear-liquid diet. You may be asked to drink a large container of solution that helps with the complete emptying of your intestines.
- Begin fasting as directed by your doctor.
General anesthesia —you will be asleep during the procedure
Description of Procedure
The procedure may be done with one of two methods:
- Traditional open incision —An incision will be made into the abdomen in the area of the diseased intestine.
- Laparoscopic technique —A few small incisions will be made in the abdomen. Carbon dioxide gas will be pumped into the abdomen through an incision. A laparoscope, which is a thin tube with a small camera on the end, will be inserted through the incisions. Special tools will also be inserted through these incisions. The laparoscope sends a view of the interior of the abdomen to a video monitor.
In either type of surgery, the small intestine will be clamped above and below the diseased section. This section will be cut free and removed.
If there is enough healthy intestine left, the free ends of the intestine may be joined together. Otherwise, a permanent or temporary ileostomy is created. An ileostomy is an opening called a stoma in the abdomen. The end of the small intestine closest to the stomach is attached to the opening. This allows intestinal contents to drain into a sealed pouch on the outside of the body. If a temporary ileostomy is created, another operation will be necessary several months later to reverse it.

The abdomen incisions will be closed with stitches.
How Long Will It Take?
About 1-4 hours
How Much Will It Hurt?
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
Average Hospital Stay
The usual length of stay is 5-7 days. Your doctor may choose to keep you longer if complications arise or if you had a large amount of intestine removed.
At the Hospital
A catheter will be placed in your bladder before surgery. You will also have a nasogastric tube. This is a small tube that goes in through your nose and down into your stomach. The tube may be used to drain fluids from your stomach or to help deliver food to your stomach. The catheter and tube will remain until you are able to eat and go to the bathroom normally.
You will have some activity restrictions, such as avoiding heavy lifting. Moving around will help prevent blood clots and promote healing. Follow wound care instructions to avoid infection. Your healthcare team will teach you how to care for your ileostomy and provide you with resources.
Call Your Doctor
Call your doctor if any of these occur:
- Signs of infection, including fever and chills
- Any redness, swelling, bleeding, or drainage from the incision site
- Your bandage becomes soaked with blood
- Stitches or staples come apart
- Persistent nausea or vomiting
- Persistent abdominal pain or bloating
- Constipation or diarrhea
- Rectal bleeding or tarry-colored stools
- Pain that you cannot control with the medications you were given
- Cough, shortness of breath, or chest pain
- Pain, burning, urgency, frequency of urination, or persistent blood in the urine
- New or unexpected symptoms
If you think you have an emergency, call for emergency medical services right away.
