An appendicostomy is the creation of a pathway from your belly button to the large intestine. The pathway is created using your own body tissue, the appendix. Using your own body tissue instead of an artificial tube will decrease the chance of irritation.
An appendicostomy is done to help deliver enemas more easily. Enemas are fluids that are placed into the large intestines to soften stool and relieve constipation. The fluids help clean out the intestines when there is a problem with the intestines or stool. Enemas may be needed in children with spina bifida, spinal injuries, Hirschprung’s disease, or constipation not relieved by medical care.
Enemas are normally given through the rectum. This can make it difficult for people to deliver the enemas to themselves. For older children, it can be difficult to have rectal enemas delivered by their parents. An appendicostomy can allow more independence for these children.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Talk to your doctor about these risks before the procedure.
Your doctor will need to make sure that enemas are effective for your condition. You will also need to show good fecal control with enemas. Good control is staying clean for at least 24 hours after emptying your bowels.
You may need to stop taking some medications up to one week before the procedure.
General anesthesia is used. You will be asleep during the procedure.
A small cut will be made just below the belly button. The tip of the appendix will also be opened. The opened end will then be attached to an opening in the belly button. If the appendix has been removed previously, a new one will be created from the large intestine. A valve will then be placed at this connection. The valve allows the enema to flow in but keeps fluids from leaking out.
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 remain outside of the belly button. The tube will be taped into place. This tube will stay in place for 2-4 weeks after the surgery until the area heals.
About 2 hours
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
The length of stay may be 1-5 days. If you have any problems, you may need to stay longer.
You will be shown how to care for your tube and deliver enemas.
Enema will be given within 24 hours of the first meal. Although, you may need to wait longer if a new appendix was created.
Activities will be restricted, including swimming. Some sports or activities can be resumed once recovery is complete. Cleaning the incision site as advised will help prevent infection. Try to keep the area clean and dry. Follow special instructions from the healthcare team on how to care for the tube.
It is important for you to monitor your recovery after you leave the hospital. Alert your doctor to any problems right away. If any of the following occur, call your doctor:
If you think you have an emergency, call for emergency medical services right away.
