I googled colorectal surgeons in Calgary, Alberta Canada.
Up came Dr. Daryl Jenken's name with ratemds'com website. He has excellent reviews from MANY people who had their colons removed by him.
These people are all alive, well, and totally thrilled. Sounds like he is very good. Ratemd's is a very reliable web site.
If you are right there in Calgary, grab a phone book and make an appointment. He sounds like the doc for you. Don't tell anyone in your family you are going.
JUST GO! This doc could be your answer.
Go, then let us know how the appointment went. Just tell him what you try for laxatives and how long it is until you poop, or that you don't. As I remember you have been posting for about 2 years or more now about not pooping. He will be impressed with that and take you seriously, anyone would.
I guarantee he will do a sitzmark test where you swallow a little pill with tiny markers in it. Then you have an xray every few days. If the markers don't move along then your colon is not working and needs to come out. The guy sounds great to me.
