I'm at work so don't have a lot of time to elaborate, but I just read an msnbc article (http://www.msnbc.msn.com/id/38743790/ns/health-health_care/) about how they can do surgeries using natural orifices - mouth, vajay, urethra etc - looks like CD is one of the problems that can potentially be treated with this. This could be very exciting news for us - imagine what it would do to recovery times if we had no external scarring after surgery?
