That's always disheartening when the experts aren't agreeing with diagnosis and treatment. This is just me, but I'd try the least invasive approach first. I'd try the medicine they can prescribe to see if it helps because I'd rather do that than stricture surgery. But ultimately, it does make you wonder about their level of expertise that they have completely different approaches. Otherwise, go ahead with the one doctor you like the best for the surgery since three concur. But personally, again, I'd try the medication first. Less invasive, less scary.
