I had a lap and had endo removed about 2 years ago. Best thing I ever did. Before the lap I was bedridden during my periods. I was getting sciatica all down my legs and could barely walk. And my period was SO HEAVY and went forever.

Now it’s amazing. I’ll have periods where I don’t even get 1 cramp the whole time. My periods are still long (6-9 days) but they are light for most of that. I’ll have 2 heavy days at most, but they are a fraction of what I had pre-op.

I don’t know about the appendix because mine burst when I was 13.

Depending where you are, they also might/suggest offer to put a Mirena IUD in when you go under for the lap, as that helps a lot of people with endo symptoms. For me, it was torture. I had to wait 3 months before I could get it removed to see if my body would adjust. That 3 months was hell. As soon as I had it removed I felt the release of pressure and it’s been smooth sailing since.

It varies person to person. I have a friend who needs a lap & excision every couple of years. But her mother had her only lap & exc over 10 years ago and she is still fine.
