Gosh! I was concerned that my esophagus wouldn't be long enough either, even though they measured it during the manometry. When they did the esophageal mediastinal dissection they were able to get enough freed up to do the partial wrap.
I know the procedure you are talking about
for stapling the stomach to make a longer esophagus. It's called a Collis gastroplasty. They do it in Pittsburgh if you have to have it re-done.
Best of luck with recovery.
