The flipping of my pouch was finally diagnosed with a CT scan in the ER when I went in with extreme pain. They saw a swirling pattern at the site of my anastomisis and kept me for close monitoring to make sure that it didn't become necrotic. They gave me enemas and pain meds as the pain of an organ twisting and flopping on itself is a whole new kind of pain. Mayo clinic also performed a test where they filled my pouch with some sort of glowing fluid, had me lay down and turned me in different positions and took images to see how the weight of the fluid in the pouch caused the pouch to react. They were able to see it flip flopping. They also noted that the pouch was rather large for its age, and that it has stretched quite a bit which may have been the underlining problem. This led them to the decision to anchor down the pouch. They felt it urgent since continuing flopping could cause necrosis.
