The fact that you are on here looking for suggestions, speaks volumes for your support. I didn't have that procedure, but during my 20 month journey, my wife goes to all my appointments with me. I couldn't do this without her being there for me. Her emotional help is everything to me. Being there for your other half means everything. It's an emotional roller coast he's about to go on and he definitely will need that extra hug and someone to hear what he is going through. I wish the both of you all the best on your journey. It is your journey as well as his. Best to all.
