I think surgeons have their own preference as whether to do open or lap. My dr, because of the position and twisting of the stomach against the heart, wouldn't consider doing it lap. I was disappointed but ultimately we have to put faith in who we are hiring.
What other surgeries have you had? Were they open?
I can tell you that the 4 days in the hospital were grueling, and the first week in general was no fun. I'm 56 and in decent health but the first week made me a weak miserable mess. Week 2 was better and today at day 18, I drove myself to work.
There is a lot of good advice in this forum. My advice is take your pain meds, force yourself to walk, take a laxative early on after surgery if things are not moving, be prepared for weird gas pain - which will go away the more you walk, and try to just go with the flow.
