Stage 1: Bowel resection
- Laparoscopic/robotic procedure: The surgeon will make four small incisions in your child’s abdomen. They will then pass a scope into one of the incisions to observe the operation. They will place surgical instruments through the other three openings.
- Colectomy: The surgeon removes entire colon (large bowel) but leaves the rectum in place.
- Ileostomy creation: The surgeon creates an opening at the end of the small intestine (bowel) and brings it through the skin of the abdominal wall to form a stoma, or ostomy. This is a temporary ostomy, which is needed until the J-pouch is created and has healed, which usually takes six to nine months. The stoma empties partially digested food into a pouch that is worn on the abdomen (belly).
Before your child leaves the hospital, we will show you how to take care of their stoma. We will also teach you information about skin care, pouch emptying, and how to put on a pouch before your child is discharged.
Most patients are discharged from the hospital within five to seven days post-procedure. The next stage of the operation usually occurs within a few months. This time frame may vary depending on the healing of the lining of your child’s rectum.
Stage 2: Pouch creation
The ileoanal J-pouch, or reservoir, is created from the lowest part of the small intestine (bowel). The surgeon will use about 6 to 12 centimeters of the ileum (last part of the small intestine) to create a J-shaped reservoir. They will separate the mucosa, or inner lining of the rectum, from the muscular wall. We will leave the muscle wall of the rectum in place along with special sphincter muscles, which hold the stool inside the rectum or pouch. This part of the operation is done through the anus.
The surgeon then brings down the pouch and attaches it to the anus. Once the ostomy is closed, the stool can travel through the entire small bowel without leaking from the anus.
The surgeon will also bring a new temporary ileostomy out onto the abdominal surface where the previous one was. This allows the J-pouch and where it is sewn to the anus to heal properly. The procedure usually takes four to five hours, depending on your child’s condition. In about six weeks, after healing and regaining their strength, your child will be scheduled for an X-ray procedure to study the J-pouch.
We will place a catheter into your child’s anus to allow a small amount of contrast solution into the reservoir to make sure the areas have completely healed. We will teach you how to begin fluid "challenges" once a day.
Stage 3: Ostomy takedown
Ileostomy is closed: This is called the "takedown" because the end of the ileum, which made the ileostomy stoma, is taken down from the abdomen wall and connected to the ileoanal reservoir. The old stoma site on the abdomen is now sutured closed. The intestinal output ("poop") can now flow directly into the internal pouch and be emptied out of the body through the anus.
The procedure usually takes about two hours to complete. We perform this operation through the same incisions as the previous surgery. Your child will stay in the hospital for three to five days and then have a follow-up visit a few weeks after surgery. They will have dissolvable sutures, and a clear plastic bandage will cover their incisions.
Once fully recovered, most people have between four to six bowel movements per day and can successfully pass gas without having an "accident."
