I don't know if your above post is old, but no, your loop procedures are not considered pelvic surgery, and of course neither are the pap smears. Since the loop procedure only involves analyzing your cervix, the doctors or nurses or equipment would not be any more superior into your pelvis, for example near your uterine (fallopian) tubes.
So, the possibility that examining your cervix would ever lead to your uterine (fallopian) tubes being damaged, scarred, or even touched is the same likelihood that brushing your teeth could scar your esophagus. They are just not close enough for anything to happen. I am not confident about a CIN three grade affecting or not affecting uterine tubes, so this is something you should inquire about further.
I am so sorry to hear about your situation. My advice first is to always seek a second opinion. There are always other options for the both of you if you're fertile, and besides that, there are always other options in life, period. Best of luck to the both of you.
Sincerely, A 4th year medical student.
