Pouchoscopy is a minimally invasive endoscopic procedure to examine an ileo-anal pouch, a replacement for the colon / rectum which is surgically created from the small intestine (ileum) as treatment for ulcerative colitis, a preventive measure in certain genetic illnesses such as FAP or HNPCC or as a procedure in the treatment of colon cancer.
In medicine, the ileal pouch–anal anastomosis (IPAA), also known as restorative proctocolectomy (RPC), ileal-anal reservoir (IAR), an ileo-anal pouch, ileal-anal pullthrough, or sometimes referred to as a J-pouch, S-pouch, W-pouch, or a pelvic pouch, is an anastomosis of a reservoir pouch made from ileum (small intestine) to the anus, bypassing the former site of the colon in cases where the ...
The capacity of the internal pouch increases steadily after surgery: from 50 cm 3, when first constructed, to 600–1000 cm 3 over a period of months, when the pouch fully matures. The opening through which the catheter is introduced into the pouch is called the stoma. It is a small, flat, button-hole opening on the abdomen.
Pouching systems usually consist of a collection pouch, a barrier on the skin, and connect with the stoma itself, which is the part of the body that has been diverted to the skin. The system may be a one-piece system consisting only of a bag or, in some instances involve a device placed on the skin with a collection pouch that is attached ...
An Indiana pouch is a surgically-created urinary diversion used to create a way for the body to store and eliminate urine for patients who have had their urinary bladders removed as a result of bladder cancer, pelvic exenteration, bladder exstrophy or who are not continent due to a congenital, neurogenic bladder.
A tube is typically also placed in the urethra or through a suprapubic opening to ensure full urine drainage and to rest the bladder during recovery. [25] The tubes are generally removed and the channel is ready to use with intermittent catheters in 4–6 weeks, [ 25 ] provided that a medical professional first instructs on how to catheterize ...
The stoma is usually covered with a removable pouching system (adhesive or mechanical) that collects and contains the output for later disposal. Modern pouching systems enable most individuals to resume normal activities and lifestyles after surgery, often with no outward physical evidence of the stoma or its pouching system.
The end of the ileum is then brought out through an opening (a stoma) in the abdominal wall. The residual small bowel is reanastamosed with the residual terminal ileum, usually seated inferior relative to the anastomosis. [2] [3] The urine is collected through a bag that attaches on the outside of the body over the stoma.
