Our expert says:
What they do with a Nissan is to fold a flap of stomach around the top part of the stomach to help the upper valve close better - this can sometimes be too tight and cause difficulty in swallowing. You may also have a bit of gall reflux into the stomach. Try Maxolon one 3 times a day 15 min before eating, and using something like Gaviscon after eating - you will need a prescription.
Redoing a Nissan will be as dangerous as the first operation - if they can't see anything specifically wrong with the scope I wonder if this is really really necessary?
