I'm looking for information on which surgeons carry out this procedure.

I already had colovaginoplasty in the UK which didn't turn out well and now I need a repair.
It has proved to be a complex situation so I'm looking for a surgeon who has a lot of experience with this particular type of surgery.
I'll consider pretty much anywhere in the world outside the UK.

Any information at all would be helpful, thanks! 

I think that Dr Preecha in Thailand has performed many of those successfully. I remember at the time of my srs when I researched different doctors he used to only create cosmetic vagina and doing subsequent colon vaginoplasty to most of his patients. I guess that makes him very experiences. That is one of the reasons he is known as the butcher of Thailand. His technique has improved in recent years and he is able to achieve functional results with penile inversion but in his old days he was doing many colon surgeries. I don't know of anybody else who has performed many colon surgeries as this is already an old fashioned technique and most of the people get good results with inversion or non inversion techniques.
