My son has a duzy of A tale! In June 2014 had a colonectomy with a j-pouch creation. In September 2014 they put him back together. In NI ember he was in so much pain they did a bunch of studies and found nice size abscess. Rare unidentifiable fungal infection they said. In January, they found the fistulia. It was connected to the abscess and the pouch, but where, no one had any idea. In March it was decided to take him off the pouch and put him back on the ostomy. as of June 2015 they knew there was a leak in the pouch but the doctors could not find it. They did countless MRI's, and CAT scans. Unfortunately in May my son was diagnosed with PSC and we needed to have an entire new team of doctors. We left our local medical school in NJ and had to go in NYC. The new team, redid all the studies our other doctors had done, and in August, found the leak! It was had to find, located at the bottom, I think at the cuff and in the back, so it is not easily seen on any imaging. I don't know what they did or how they did it, but they found it. They put in a mushroom drain, and it has since started to close. Next week, my son is going in for a pouchoscopy to see if it has closed completely. I don't know what the next steps will be. But I think we are finally on the right track. Good luck! I don't know how you have lived this long with the darn thing!
