Nissan fundoplication? Best places to go and is it advisable? Or can I get a esophogus replacement?

Depends. I know nothing of your problems or condition here. Surgery is performed when there is expected to be a beneficial result of the operation. I do not know why you might or might not need surgery. Esophagus replacement is a very major surgery usually only performed for cancer of the esophagus.
Fundoplication. Fundoplication is recommended for people with medically unmanagable gerd symptoms.Recommend visiting a tertiaty center if you want fundoplication.No need fort esophageal replacement.
