Years ago when I was researching a revision from RNY to DS Dr. Dakin was at Mt Sinai with Dr Pomp. He was fairly new but considered capable as far as a virgin DS. I don’t recall him performing revisions at that time. I imagine that he currently has tons more experience.
I decided against Mt Sinai originally when considering surgery because of aftercare issues when I was first researching the DS. In 2002 Mt Sinai was having several issues with aftercare. There was no questions regarding surgical skill but aftercare at Mt Sinai resulted in deaths. Dr Dakin is with a different hospital now so those concerns are gone
I checked out several surgeons in the NY tri- state area. I ended up going to California for revision surgery ( RNY to DS) with Dr Keshishian.
I apologize for rambling on.
