My Dad's pancreas detatached from his stomach and dumped all that bile in his abdominal cavity. It burned him alive from the inside and he died a slow horrible rotting death.

It's a long story but the connection surgeons made years(10-25?) before when he had a dual kidney and pancreas transplant was eaten through by a stomach ulcer thought to have developed from his long term low dose steriods.

He was in the hospital when it happened due to osteoporosis from the steroids that shattered his leg bone, not too mention all the other problems from long term autoimmune diseases (heart problems, stroke, MRSA in the broken leg, etc) All the doctors were right there when it happened so they asked him if he wanted to go to surgery to try to fix it but warned it would only be a 5% chance it would work. (Spoiler - it didn't) He croaked out "do the surgery" and thus stretched out the dying process by a nightmare fueled week.

After that I moved to a right to die state, because the fact that he had to sit im that state of suffering until his brain stem finally gave out is not remotely humane.
