I just had the most recent adhesion removal lapro one yr ago... and I was going to have a coloscopy .. just to have base lines for everything since I turned 50 this yr. after the lap, the surgeon's report was explaining how there was such a mass of adhesions in the small and large intestines, that she seldom would recommend someone NOT to undergo a coloscopy, especially if it runs in the family, but in my case she was emphatic as there is a thick band of adhesions kinking the colon and adherred to the liver.. reason she said not to have one was the possibility of puncturing through the colon wall trying to get passed the bans of adhesions.
this is just a "for what it's worth." I opted to not have one schelduled until/unless I feel that might be a problem.
