I had a total colectomy 20 years ago for Crohn's and it was the best thing I could do for myself. It really hasn't given me a problem.
Now, about trying to get bowel sounds so you can eat. Start thinking of all the food you want to eat that you haven't been able to eat for years. Get out magazines. Have your visitors bring magazines that have pictures of food in them. Trust me, you will get the bowel sounds! My doctor gave me that bit of advice before surgery so I packed some magazines in my suitcase. Give it a try. I hope it helps!
