What to Expect
Prior to Procedure
The surgical team may meet with you to talk about:
- Anesthesia options
- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before surgery
- Fasting before surgery, such as avoiding food or drink after midnight the night before
- Whether you need a ride to and from surgery
- Tests that will need to be done before surgery
- Cleaning the bowels
Description of Procedure
The surgery may be done in one of two ways:
An incision will be made in the abdomen. The diseased section of intestine will be removed. If any healthy intestine is left, the ends will be joined together. If not, an opening (stoma) in the abdomen will be made to allow stool to exit into a bag. The surgical incision will be closed with stitches. A bandage will be placed over the area.
Small incisions will be made in the abdomen. A tube will be passed through one of the incisions. It will push gas into the belly. This will make it easier for the doctor to view the area. A camera will allow the doctor to see inside the belly. Other tools will be passed through the incisions. They will be used to remove the diseased section of intestine. If any healthy intestine is left, the ends will be joined together. If not, an opening (stoma) in the abdomen will be made to allow stool to exit into a bag. The surgical incisions will be closed with stitches. A bandage will be placed over the area.
How Long Will It Take?
About 1 to 4 hours
Will It Hurt?
Pain and swelling are common in the first week. Medicine and home care help.
Average Hospital Stay
The usual length of stay is 5 to 7 days. If you have any problems, you may need to stay longer.
At the Hospital
After the procedure, the staff may:
- Give medicines to control pain or nausea
- Teach stoma care, if needed
- Place a tube through the nose and into the stomach to give the area time to rest
- Give IV nutrition while the intestine heals
Recovery will take 1 to 2 months. Physical activity will be limited during this time. You will need to delay your return to work.
Call Your Doctor
Call your doctor if you are not getting better or you have:
- Signs of infection, such as fever or chills
- Redness, swelling, excess bleeding, or drainage from the incision
- Lasting nausea or vomiting
- Pain you cannot control with medicine
- Problems passing urine or stool, including bleeding
- New or unexpected symptoms
If you think you have an emergency, call for medical help right away.
