Could your colleague be pulling your leg or have gotten the story wrong? There is a k-pouch which involves a valve being inserted in the abdomen for self-catherizing, but it's not a plastic recepticle that holds waste. One of the reasons why colon transplants and plastic replacements will never succeed is that there is a better option and that's the j-pouch. Since it's constructed out of the small intestine there is never a worry that the body will reject it and also there is no need to stay on transplant drugs (like prednisone).
