My J-Pouch twisted a few years ago. It was very painful. Nothing would pass through and I couldn’t eat anything because I would throw up. The pain was like having severe labor pains every few minutes. It took them several days to figure out what was wrong. I had to have my pouch disconnected and a temporary ileostomy to rest and heal the j-pouch. Later it was reversed and everything thing has been fine. The surgeon tacked my pouch to my spine.
