Ileo-anal pouch formation

The ileo-anal pouch can be formed over a one, two or three stage procedure. Your consultant will determine which operation is most appropriate for you.

The first stage involves removing the whole colon, leaving the rectum in place and forming an ileostomy (where the small intestine is diverted through an opening in your tummy).

The second stage is when the pouch is formed but to allow it to heal a temporary loop ileostomy is formed.

The third stage and final operation is when the ileostomy is reversed and natural bowel function is restored via the pouch. It is commonly performed as keyhole surgery but can also be an open procedure (larger cut on the abdomen).

Your consultant will let you know how best to prepare for this type of surgery.

After the operation you will have an intravenous drip, which is normally in place for 24 hours.

A tube inserted to drain the bladder (catheter) is normally kept in place for two to three days.

An abdominal drain (small tube passing through the abdominal wall) is often used, as is a small tube which is passed through the anus into the pouch. These are normally removed after a few days.

You will need to remain in hospital for around a week, depending on your recovery rate. Once your bowels start to work again you may find that your bowel motion is very loose and more frequent in nature. This will recover over time.
