My Colorectal surgeon has always given me warnings every time he has taken me into surgery...warning me that he wouldn't be able to do the pouch (I have a k pouch), that he wouldn't be able to do it in 1, 2 or 3 steps...and then every time that he took me back in for a repair has warned me that I might not have enough intestine to fix it or that I might end up with an ileo if things go bad...they have no choice...they must be honest because the facts are the facts...They really do not know what they are going to find once they get in there and it may alter their ability to do what they promised to do.
It is not just a question of experience or skill but a question of adhesion but also the rest of your anatomy and biology...
I have been fortunate that he has always kept his promises but there may come a time that he won't be able to fix me...
I consider it honesty and not a disclaimer. The only surgeon who never warned me of a possible negative outcome turned out to really be incapable and unskilled.
Hope that this helps.
