Pouchoscopy

Learn about a test that examines the lining of your ileoanal pouch.

What we do

A pouchoscopy is a procedure that lets a health-care provider look directly at the lining of your ileoanal pouch (also called a J-pouch). This pouch was created from your small bowel during surgery.

What to expect

The test helps your care team find the cause of your symptoms and manage your condition.

During a pouchoscopy, a thin, flexible tube with a camera, called a scope, is gently passed through the anus into your pouch. This lets your health-care provider check for problems such as: 

  • Ulcers
  • Inflammation
  • Polyps (small growths similar to warts)

A pouchoscopy may also include taking a small tissue sample, called a biopsy, from the lining of your bowel to help with diagnosis. A small instrument called forceps passes through the scope to gently remove a small piece of tissue. This sample is sent to a laboratory for further examination. Polyps can also be removed in a similar way. The procedure usually takes about 10 minutes. Most people find it painless.

What to bring

  • Health (OHIP) card or valid health-care coverage
  • Someone to help you get home if you receive sedation
