Thank you all who have replied. The replies got my juices going and gave me a direction to look. We were feeling pretty hopeless and abandoned when the surgeon said he wouldn't make it through surgery, since that's what he had been working for all of this time.
I have found it's not the end. There are other treatments, like more chemo, immunotherapy, etc. out there, and after reading some of the posts in here, and on other threads, it looks like surgery would not have been a good thing for him, even if he had survived it.
We had the j-tube removed and he is almost back to his old self after months of suffering with it. It always hurt, and felt like it was taking up a lot of room. It extended a lot and was always catching on stuff. He's a really active guy and there was so much he couldn't do because of that tube. He really didn't need it, since he could always eat, but he's had it in since Nov.2022 working toward surgery.
We meet with his oncologist next week and right now, I'm thankful his tumor has shrunk enough from treatment that he has no pain, the j-tube is out so he feels good and he's eating normally. Thank you everyone for your stories and information that helped me get back on track!
