I'm going for the esophyx procedure this fall. I find this option the best for me. Have you seen the video on line for it? It's very simple. My doctor's nurse said her 17 year old had it done and is doing great. She can burp and is totally off medication. The operation takes about
1-11/2 hours I'm told. Get him lots of Boost, ensure, soup, and ice cream. His throat will be sore for a few days.
I'm in the process of registering to see a doctor in my state who has done over 130 procedures and teaches others how to do it. I found him on the internet. Let me know how your son does.
