Just my opinion too, but it sounds like it's time to give it everything. And please see that he starts using his PEG for nourishment. My DH has had to use it since the day after his surgery. It's routine now and nothing to be afraid of. No one knows he has it. Nothing shows and we plug him in at night and he is done in the morning. He actually has a J-tube which takes longer to pump in, but he could not survive without it. DH is 62, still working fulltime and fishing. He could not do this without his PEG.
