How is a j-pouch done?

It is an operation: J pouch is an operation to preserve continence in patients requiring removal of colon for either ulcerative coliitis or crohn's colitis. It can be done in 2 or three stages depending on the severity of the patient's illness and the presence or absence of steroids.

The first steps: For the creation of a small intestinal pelvic pouch, also known as a j-pouch is to remove the colon and rectum. Then the pouch is made by folding the small intestine into the shape of a "j" - and sewing the sides of each limb together. The base of the j is sewn to the anal muscles.
