Reasons for Procedure
Enemas are normally given through the rectum. This surgery is done to make it easier to give an enema to a child. Enemas are fluids placed into the large intestine. The fluids help clean out the intestines when there is a problem. They may be needed in children with:
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
- Excess bleeding
- Problems from anesthesia, such as wheezing or sore throat
- The need for repeat surgery
What to Expect
Prior to Procedure
The surgical team may meet with you to talk about:
- Anesthesia options
- Any allergies your child may have
- Current medicines, herbs, and supplements that your child takes and whether they need to be stopped before surgery
- Fasting before surgery, such as avoiding food or drink after midnight the night before
General anesthesia is used. Your child will be asleep.
Description of the Procedure
A small cut will be made just below the belly button. The tip of the appendix will be opened. The opened end will attach to an opening in the belly button. If the appendix was removed, a new one will be made from the large intestine. A valve will then be placed. The valve allows the enema to flow one way.
A tube will be passed through the belly button and valve. The tip of the tube will stay in the appendix. The end of the tube will stay outside of the belly button. The tube will be taped into place. It will stay in place for 2 to 4 weeks.
How Long Will It Take?
About 2 hours
Will It Hurt?
Pain is common in the first few days. Medicine and home care can help.
Average Hospital Stay
The usual length of stay is 1 to 5 days. If your child has any problems, they may need to stay longer.
At the Care Center
The staff will:
- Give your child pain medicine
- Teach you and your child how to care for the tube and give enemas
It will take 4 to 6 weeks for the site to fully heal. Physical activity will need to be limited during recovery. You may need to delay your child's return to normal activities.
Call Your Child's Doctor
Call the doctor if your child is not getting better or has:
- Signs of infection, such as fever or chills
- Redness, swelling, bleeding, or discharge from the incision
- Pain that cannot be controlled with medicine
- Trouble using the tube
- The tube falls out before your child has healed
If you think you have an emergency, call for medical help right away.
