I know it's a hard thing to face, but if you can get things straightened around, it'll be well worth the struggle. Please be sure to do your research and find a skilled and experienced surgeon who has redone many Nissens. Get more than one opinion if you need to. Now, you may already have a great surgeon, and your problem is a fluke. Jut give it some thought.
Bill is correct. At this point, the Nissen is the "gold standard" for repairing the LES. As other procedures around longer, it's likely that technology will move things forward. Our own Joy will be helping this process by having the EsophyX soon. We all need to send her healing thoughts, so she can get healthy in time for her pre-op testing!
Good luck, Oldpoopie. We're here to support you through your testing and search for answers!
