Your doctors seem on top of things, and experienced to do complicated surgeries, others may not, and probably can do the next phase, so there may not be a need to go elsewhere, which hopefully it's not needed, Dr. Eric Gendon, at Mt Sinai in NYC, may have articles on resection of the esophagus, and believe was the first to do artificial esphogus implants with Dr Mark Urken, who is now at Beth Israel. Good luck.
