I had my first LIS mid Dec. 2007 and my second mid August 2008. I had to have my second LIS since 3 CRSs confirmed that my sphincter was still super tight. After my second LIS my CRS said that he could not even find the scar tissue where the first LIS was performed and said he never saw such case. My sphincter actually completely regenerated and regained it's full strength.
In my case I just had to have second LIS since I would never completely be "home-free" otherwise. I am very glad I listened to my intuition and searched for definite solution for my problem.
Passion- in my humble opinion, I do not think you match a typical case
. I would seek second opinion if I were you
.
I wish you the best of luck
