Hi: I read your post. You might also interview Dr. Marvin , www.doctormarvin.com
He does the single incision. I might add that it is only an option if you are on the smaller side.
It must be technically possible to get at the stomach from one incision in order for the MD to do this technique.
Just thought I'd let you in on that since it is not possible for every patient.
Good luck.
Thank you.
