Hi. I'm sorry that your father's in pain. I had a very long and involved cyto-reductive surgery + Hipec... The post-op pain was bad but I had a morphine pump that delivered morphine continously + a button to press to have an immediate dose... Does your father have something like that? He should really talk to his surgeon about this pain. If he doesn't prescribe something for the pain, you could look for a pain-spacialist doctor/team.
If you have other questions, I'll be glad to help you.
All the best.
