I am wondering whether, if you need Crohn's surgery (not on an emergency basis) whether it is best to only look at a surgeon in the same hospital as your GI doctor is affiliated with, or whether it is also possible to use a surgeon in a different hospital. For example, if I conclude that the best surgeon for complicated strictureplasty is at NY-Presbetyrian but my GI is with Mt. Sinai, is it best to seek a surgeon at Mt. Sinai, or somehow try to have them work together?
