I am a Crohn's pt who developed tortuous colon about 2 years ago. They were unable to complete colonoscopy even using a pediatric scope. MRI revealed tortuous colon with colonic stricture and significant thickening of bowel wall. I had to go to a hospital who had Advanced Endoscopy to perform balloon dilation on the stricture. I realize I will never have "normal" stool but as long as I keep things soft I can maintain. I hope this info helps.
