The reason that continent pouches aren't mentioned more is that they were largely replaced by j-pouch surgery so not as many doctors perform that surgery. If a j-poucher has chronic pouchitis a continent ostomy is contraindicated. Even if one is doing 'okay' with pouchitis in their continent ostomy, I would think that opting for the chance of no pouchitis would be more desirable.
Ostomies aren't at all bad. I thought I'd hate it but it was perfectly fine and I was able to do and eat absolutely anything I wanted.
