Your situation sounds miserable and I'm so sorry for it. One option might be to contact Dr. Dietz, explain the situation, and if he thinks you need a scan ask if your local doctor can do it and send the results to Cleveland. Or maybe Dr. Dietz talks your doctor through the procedure. Given your condition I can empathize with not wanting to travel six hours.
When you irrigate how much water are you using? I find that if I've eaten something that greatly thickens up the stool then I need to irrigate as much as 60 ML 6 or 7 times. It seems like a lot to me but I irrigate until the stool is very thin and watery – – not unlike when you had The K in 24/7, for the four weeks after the surgery.
I urge you to keep a diary, as it will help analyze when the pouch works properly and when it doesn't. Keep us posted please, Janet
