Hill Grade IV??

I was able to get my results back from my work up and was never told but apparently my valve or flap, I’m not fully sure is Hill Grade IV and I have a small hiatal hernia. I tried to do more searching on this and either got confused or met with people saying surgery is needed but I’ve never been spoken to about this, my GI who I will be no longer seeing also kinda brushed off my Gastroperisis diagnosis at first so I can’t say I’m shocked. I guess I’m just nervous and curious if anyone knows how to explain this to me or if I will need surgery or if it’s just a watch and see type of deal, thank you all!
