My dad had stent last monday-having a lot of pain. Need advice.

I read everyday but don't post much. My 65 year old dad has stage 4 EC with Mets to liver and nodes. Dx on July 16 from bx and Pet scan. He started chemo 2 days later, which he has tolorated very well, but the swallowing has gotten worse. Many of you gave great advise about a J-tube but my stubborn dad won't do it as he thinks it means that's the end and he would be some kind of vegtable hooked up to be fed. We know that is not true but at this point he has refused. Part of the resistance comes from having my little sister die last summer due to a botched Gastric Bypass. She was on tube feeding then TPN and suffered tremendously for 2 years before she passed at my parents home 14 months ago leaving her daughter for my parents to raise.
No to the stent. He had it placed on the 23rd. He has had a lot of pain, burning, and vomitting since then. His Dr said the pain was from the "streching" and shouldn't last more than a couple of days. He started taking Prilosec for the burning and sleeping propped up. He is worse. He says he can feel the tumor being "pressed". The vommiting is scary. When they placed the stent he was told that the cancer has grown larger and when they touched it, it bleeds so he may need blood transfusions. Only one of the days did he throw up dark blood and what looked like some kind of tissue. His MD said it was dead cancer cells. That sounds like crap to me. Has anyone heard of throwing up part of your dying tumor after chemo?
We know the risks of stents, migration, heartburn, ect. Does anyone have any experience with a stent? I remember Unclawed dad did and was not good. Anybody with advice or ideas to make this stent experiece better? How long did it take to get some relief from the stent?
Other than the swallowing problems and some fatigue my dad had been doing well. He still works full-time at the hospital where he is being treated. He loves his job and wants to work til the end. He is being treated and surounded by the doctors and nurses that are his friends and co-workers. I believe they have his best interest at heart but I question there ablilities sometimes. I know I'm being a nagging daughter, but this is not a cancer center. He did get a second opinion from a major hospital with an EC Center. They gave him the same advice and his drs do still consult with the EC Center on his treatment. I want my dad to get his treatment there but it is 100 miles away and out-of-network for insurance. Financially, being treated at his hospital is great as it is all paid for, but I think the surgeons and staff would be much more skilled at the other. Both sets of doctors agreed that EC is the beast and the outcome isn't going to change if he is treated in his hometown. How can that be? Dad had this super positive attitude at first that he was going to beat this but I think his choices in care are showing otherwise. I know we could never get him to fly to another part of the country to another cancer center for a 3rd opinion.
Between his stubborness and stent troubles I don't see this ending well. I take that back. It will end well in that my dad is Saved by Christ and walks his faith. He will end this journey in Heaven at peace with Jesus. It is the in between now and then that scares the H@%% out of me!
Thanks for your support. I pray daily for the EC board.
