The k pouch has been fantastic for me, relative to the multitude of problems with the J pouch. although certainly not without some complications. It took a year for me to be completely comfortable with it – – that year involved squatter toilets some nasty out houses, forgetting the catheter from time to time, dealing with odor, learning what foods I really can't eat and the such. But I'm on an even keel and appreciate the surgery. I say this as encouragement for you to hang in there. It's worth it.
Is your doc for the blockage in the same hospital system as the surgeon, or indeed the same doctor? When can they get a specific diagnosis and how do they anticipate treating whatever it is? Janet
