What is a Pouchoscopy?
Pouchoscopy is a procedure that allows your physician to examine the lining of your ileo-anal pouch for inflammation, abnormal growths or tissue. An ileo-anal pouch is a surgically created pouch to replace the colon and rectum

What should I expect during the procedure?
Medicine will be given through the IV line to help you relax and feel drowsy. During a pouchoscopy, the doctor inserts a flexible tube called an endoscope into the anus and advances it slowly into the pouch. You may have a feeling of pressure or fullness during the exam. The doctor may take a painless biopsy of the lining of the GI tract for closer examination by a pathologist.

What should I expect after the procedure?
The doctor will speak with you about the initial results of your exam. You may feel bloated after the procedure. Following the exam, you may resume your normal diet unless instructed otherwise by your physician. You will not be able to drive home after your exam due to the sedation.

What are the possible complications associated with Pouchoscopy?
Although serious complications are rare, any medical procedure has the potential for risks. A nurse will review all potential warning signs with you before you leave the endoscopy center. Risks include perforations or tears in the lining of the GI tract, bleeding from the biopsy site and reactions to medications used during the procedure.
