Although this post is over 2 years ago, I'm wondering if you ever got the biofeedback, bc I too have paradoxical contractions and a floppy pouch, causing incomplete emptying and leakage, diagnosed by Dr. Bo Shen. I couldn't go through with the first biofeedback visit bc they couldn't get the probe through my anus, it was such excruciating pain. So I told Shen that I am going to dilate myself slowly with a set of Hegar Dilators until I can get 18 mm up me without pain. I'm barely up to 16mm now. My surgeon, Dr. Gorphine, who did my jpouch back in 1996, always told me I had strictures, and should do self dilations. Unfortunately he stopped practicing a few years ago. I very often have a sore butt bc I strain too hard and I'm pretty sure it must be due to strictures which blocks the output.
