I had my operation on Feb 18th this year with a Endo specialist who only does excision, he specialises in that field. I found out i had Endo on alot of organs and that my uterus was attached to my bowel, he was able to seperate this and excise the endo as fortunately the Endo had not penetrated the bowel. He had recommended two operations if the Endo had penetrated so i would be more prepared. My MRI only showed up the deep penetrating Endo that i had elsewhere so he wasn't expecting it to be anyway.
I can tell you for first time i feel amazing, my ibs symptoms have all gone with only the occasional painful bowel movement but its a different pain so most likely due to everything healing inside.
Life was miserable before as dramatic as that sounds its true, i would sometimes not be able to leave the house due to needing to stay close to a toilet!
This is my first excision surgery as my previous was the good old burn it off rubbish! I already have more energy, sleep better, feel so much better its weird like a fog has lifted. I'm realistic i know i may need another surgery down the road but hopefully will be years away and minimal in comparison or maybe I'll be one of the lucky ones. Sorry to jump in post but hopefully this will give you hope.
