Yes not many do this procedure and he never trained anyone how to do this either at Cleveland Clinic. I have heard its only about 60% effective. How did he diagnose your prolapse and what are your symptoms? When Remzi first did my redo Shen told me I had a small prolapse, and said treat it as I would a hemrhoid I don't believe I have ever had an issue with this"prolapse". Dr Remzi said its not a prolapse and my new GI and surgeon who have scoped me since never mentioned it.. Don't get me wrong I love Dr Shen, as I had him for 11 years.
