I wrote on your other thread some of my thoughts about laproscopic vs open procedures. Generally what surgeons say is that they'll attempt the procedure laproscopically, but there is always a chance it will be switched to open. I don't think there is a surgeon out there who can promise a laproscopic procedure without the possibility of an open procedure.
Your extensive hernia situation is something I wasn't aware of in my other post. If you find that the most experience and skilled Nissen surgeon recommends open, I'd go with open.
Bill, a moderator here who hasn't been around much lately, has had the procedure both laproscopically and open, and really didn't find the open procedure much different in recovery. Obviously it will require a longer hospital stay, but I can tell you that he was pleasantly surprised with the open procedure. His comments were very comforting to anyone anticipating the possiblity of an open procedure. His handle is opnwhl4, and if you go to his profile you can find his email address. Also, you could look for other posts he's written by searching his name in the upper right hand corner of the page.
Good luck with your decision!
