I did not have colonic inertia but my understanding of the condition is that patients of CI just don't have the peristalisis that moves waste along the colon and out the rectum. I don't know if there is treatment, other than surgery, for difficult cases. I don't know if you are considering surgical intervention or just continued treatment but the Cleveland Clinic would be ideal for either. If you are considering surgery there are hundreds of very qualified CR surgeons around the country that would not involve as much travel, that is if you don't live in Ohio.
Many CI patients get a j-pouch (which is what I have due to UC) and again, that surgery can be performed anywhere by a qualified surgeon. If you choose to go that route, do your homework on the surgeon. I can give you some tips if you like.
