Hi granny b,
If you search for "paraesophageal hernia" in the upper right hand corner of the forum page, you can find other threads and posts on the topic. There are many here who've had that surgery, and you can read about their experiences.
Pretty much all surgeons tell their patients that there is a possibility that their surgery might be switched to an open procedure. That happens when it becomes too difficult to do the procedure laproscopically. In many cases it's because the field of view is obscured, or the procedure is too extensive or difficult to do laproscopically.
Bill, a moderator here, has had to have his Nissen redone. His most recent Nissen was done as an open procedure, and he didn't find it much different at all as far as healing goes. He did have to remain in the hospital longer with the open procedure. Often laproscopic Nissens only require an overnight stay.
Again, glad you've joined the forum!
