Lauren, a BCIR functions the same way as a K pouch, but differs in the way it is constructed. It has a “living collar” placed around the stoma access to the pouch and constructed out of a segment of small intestine (to reduce the chance of valve slippage), and the pouch is shaped differently to reduce the chance of fistulas. Both procedures have a high success rate and patient satisfaction. More information can be found on this link: https://www.ileostomy-surgery....ing-as-a-kock-pouch/
