Not sure...
I had problems oct. 2000, when I was 17.
At first the doctors thought it was appendicitis and while removing my appendix they found dense chronic adhesions encasing my appendix, colon, bowels, etc. They closed me back up and sent me home. A few days later I had the same horrible sharp pains and went back to the emergency room, where the doctors performed an exploratory surgery and discovered the adhesions had caused a blockage in my intestines (most likely causing the pains). But the doctors were totally at a loss to explain where the adhesions came from.
My mom remembered taking me into the emergency room when I was about 5 and the doctors then thought I had a kidney stone -- but it was gone the next day. The doctors in 2000 determined that (since kidney stones are so rare in children and appendicitis is not) my appendix prolly ripped a little then and the antibiotics healed me, but the fluid from inside my appendix kept seeping out over the years -- causing the adhesions.
However it took them months to come to this conclusion...And I quote directly from the operation report) "this is the best explanation I have for the extensive adhesions which I found." -- which lead me to believe that they still may not know what really caused them...
At one point they were worried thinking I might have endometriosis.
And i've had some tests done since, but because they kinda moved away from the endometriosis, never really worried about that too much.
I was just curious, because i'm still not totally at ease w/their response, if i've been having normal yearly checkups, but noting too extensive, but my mom thought, that if it was endometriosis it would show up in a normal pap smear... I was just wondering if that is correct?
