I wish you all the best for a successful surgery and recovery.
The surgeon should be able to give you an opinion about how the surgery went. You may want to ask what nodes/tissue was actually removed and why. And why wasn't more stuff removed?
You will be on the healing side of surgery and as the sedation wears off you will have some discomfort. This is the day to focus on feeling better and having your pains taken care of. I remember having a lot of upper body cavity pain. They all said it was from the gas but I think it was more of a wrong placement of my arms during surgery. My shoulder hurt worse than the surgery site.
I wouldn't rush a doc's opinion before the final pathology. Just hang in there for the week and be hopeful. Concentrate on taking good care of that catheter. Make sure that you understand all of the instructions for cleaning and use before you leave the hospital.
Get some rest,
