UPDATE 2: A doctor friend of mine writes:
"Just wanted to let you know that I've seen those surgeries, and connecting the colon to the vagina is not all that hard to do. In fact, its one of those things that surgeons 'double check' to make sure they haven't done."I had no idea. Regardless, if you are a surgeon, for the love of god, please double check.
