Good luck with your surgery. I wish I had an answer for you. I had a proctocolectomy due to Crohn's, and it took care of my problem. You might get an answer quickly if you post this question under the TOTAL COLECTOMY topic, since a lot of people who had colectomies due to constipation post there. I hope your surgery goes well and takes care of your problem completely. Please keep us posted on how you're doing.
