I had my surgery in Philly as well, but at Pennsylvania Hospital by Dr. Robert Fry, chief of colorectal surgery at Univ of Pa but does his operating at Pa. Hosp. I was not a candidate for j-pouch (too many other health issues at the time and also 63 yrs old) but am happy with my ileo.
Back to NY....I heard a LOT of positive feedback from people who have had surgery at Mt. Sinai, so if I lived closer to NY, that is where I would have gone. Good luck!!!
