Ileoanal pouch surgery for ulcerative colitis
An ileoanal pouch, usually a J-pouch, lets someone who needs their large bowel removed for ulcerative colitis avoid a permanent stoma. The colon and rectum are removed, a reservoir is made from the end of the small bowel and joined to the anus. It is normally done in two or three stages, and most people with a working pouch open their bowels around five to seven times a day.
Who is a pouch for?
Most people with ulcerative colitis never need surgery. An operation is considered when:
- colitis keeps flaring despite steroids, immunosuppressants and biologic drugs, or the side effects of those drugs are unacceptable;
- an acute severe attack does not settle with hospital treatment;
- colonoscopy surveillance finds dysplasia (pre-cancerous change) or cancer;
- a person has familial adenomatous polyposis, an inherited condition causing many polyps.
Removing the colon and rectum cures the colitis itself. The choice is then between a permanent end ileostomy and a pouch. A pouch is generally not advised in Crohn's disease, because the inflammation can return in the pouch and cause it to fail.
The stages of surgery
The number of stages depends on how unwell you are and which medicines you are taking. A common three-stage pathway is:
- Subtotal colectomy and ileostomy. The diseased colon is removed and a temporary ileostomy formed. This gets you off steroids and back to health, and confirms the diagnosis from the removed bowel.
- Pouch formation. Months later, the rectum is removed and the J-pouch is made and joined to the anus. A loop ileostomy usually protects the new join while it heals.
- Ileostomy closure. After a check that the pouch has healed, the loop ileostomy is closed and the pouch starts working.
Fitter patients may have a two-stage operation. Keyhole surgery is used wherever possible, which reduces wound problems and adhesions.
Living with a pouch
A pouch is not a normal rectum. Stools are looser, and it takes several months for the pouch to stretch and settle. Most people:
- open their bowels around five to seven times in 24 hours, often once at night;
- can defer going to the toilet, and are continent during the day;
- adjust their diet to thicken output, sometimes with loperamide;
- return to work, sport and travel.
Most people with a pouch say they would choose it again.
Risks and longer-term problems
| Issue | What it means |
|---|---|
| Pouchitis | Inflammation of the pouch causing frequency, urgency and cramps. Common: up to around half of patients have at least one episode over the years. Usually settles with antibiotics. |
| Leak from the join | An early complication that may need drainage or further surgery. This is one reason a covering ileostomy is used. |
| Bowel obstruction | From adhesions; less likely after keyhole surgery. |
| Pouch failure | A small minority eventually need the pouch removed or defunctioned, more often when the diagnosis later proves to be Crohn's disease. |
| Fertility | Pelvic surgery can reduce female fertility. The reduction appears smaller after keyhole surgery. Some women choose to complete their family before the pouch stage, which is worth discussing early. |
Choosing a surgeon
Pouch surgery is specialised, and outcomes are better in experienced hands. Ask your surgeon how many pouches they perform, their leak rate and how they will follow you up. Mr Papettas performs restorative proctocolectomy with ileoanal pouch, alongside his wider keyhole bowel practice:
| Measure (Mr Papettas, audited) | Result |
|---|---|
| Major bowel resections as first surgeon | 500+ |
| Anastomotic leak rate | Under 1% (national range 3 to 8%, NBOCA) |
| Elective mortality | 0% |
| Operations completed by keyhole | 95% |
| Conversion to open surgery | Under 5% |

Common questions
How many times a day will I go to the toilet with a J-pouch?
Most people open their bowels around five to seven times in 24 hours once the pouch has settled, often including once at night. It improves over the first year.
Can I have a pouch if I have Crohn's disease?
Usually not. Crohn's can recur in the pouch and lead to it failing, so a pouch is normally reserved for ulcerative colitis and familial adenomatous polyposis.
How long does recovery take?
Each stage needs a hospital stay of several days and a few weeks of recovery. From first operation to a working pouch typically takes several months.
Will a pouch affect pregnancy?
Pregnancy after pouch surgery is usually safe, but pelvic surgery can reduce fertility. Discuss family plans with your surgeon before the pouch stage.
