It sounds like you picked a winner. You must live near a big city to find a surgeon with that much experience. I'm sure your GI doc wouldn't refer you to someone he/she thought was inept, but it's good to check and recheck just to be sure. There's nothing more important you can do.
The next thing, is to prepare yourself for the recovery. Lots of surgeons seem to downplay the challenges of recovery (I might say most or all)--probably because they've never experienced them.
Now, I was pleasantly surprised by the recovery (I had the surgery in February 2009), but believe me, I was prepared for the very worst. The first weeks have their difficulties, but you'll get through them just fine. Your wrap will become progressively more swollen through the first two weeks, peaking at two weeks, then gradually swelling reduces. Obviously, your swallowing gets worse before it gets better.
It's not easy, but if you can get rid of all expectations, and try not to force your recovery, things will go much better. Your recovery will be as it will be. You need to just follow along the path it chooses. I see lots of people come through here who just can't wait to get better. (Don't we all feel that way?) However the more you rail against what is, the more difficult that reality is.
I was told by a more experienced member here, that most of the healing takes place in the first six months, but it continues for a year. That's not fast, is it? You'll heal quickly on the outside, but your upper GI tract will be revamped, as the cobble up a new LES for you. It takes time for it to heal, settle in, and get used to its new form. That's to be expected, don't you think?
Your stomach will be swollen at first, so you'll feel full with very little food/liquid. You'll want to eat small meals throughout the day. Once time gets closer, you can start a new thread asking for pre-surgery advice, and how to get ready for post surgery challenges. If you have the right attitude, you'll find the recovery very "doable".
Be sure to ask your surgeon (if you haven't already) his eating protocol after surgery. Some here have had to be on liquid diets for weeks, others are put on liquids at first, then soft foods. My surgeon had me on liquids in the hospital, soft foods for the first five days (until I saw him), then anything I could chew to a liquid (being warned to stay away from steak and soft breads). He trusted me to make good eating choices, and I did. You'll want to take small bites and chew, chew, chew. Many people follow their swallowing with liquids...water or tea.
So...hope I haven't thoroughly confused you! It sounds like you're making the right (only) decision to join us as a member of the "Wrapped Club". You'll do just fine, and will be glad you had the surgery, once you get past the early weeks of recovery. By four months (probably earlier, but I remember the four months for sure) I went on vacation, and was able to eat normally...that's not too long to wait!
Congratulations on making a tough decision...don't worry about the post-op pain. It's very bearable, and doesn't last long. You'll read about shoulder pain caused by the air they pump into your stomach so they can do the surgery. Walking helps a lot. I had some, but walking helped me...some have it worse.
Good luck with your surgery! We'll be here to support you before and after!
