Hi Kara, the surgeons at the CC are the best for kpouches. If they advised you to wait, they must have surgical rationale. Why don't you give their office a call to clarify?
It could be a number of reasons, a. to have your digestive track settle down, b. to gain weight, c. to gain strenght, etc.
Very sorry to hear about your chronic pain, they should have addressed this with you at your appt while advising you to wait on the KP. I'd ask about that, too.
Best, Janice
