It seems that you have VERY competent CRS
since he has a definite plan and is also wiling to do all that it takes to make you feel better and solve your problem !!!! He also is one of VERY rare ones that knows about and uses manometry - KUDOS to him !!!!! He also knows that he can examine your anus under anesthesia MUCH MUCH better than he can EVER do while you are awake !!!! They administer special medication to anus that makes it relax 100 % and it can be done only while person is fully sedated. Anus relaxes so much that every single fold can be examined without a problem and/or extra stretching or "trauma" to the anus. Your CRS obviously will not spare your insurance from extra expense and extra procedures to make you comfortable and find the BEST approach for solving your problem ! I am VERY VERY impressed with your CRS and person who did my second LIS and fixed me forever (KTW, knock knock knock) was like that
!!!
If I were you, I would let him do whatever he needs to do while you are already "under"
. I had great result after my second LIS. I had great result after my first LIS also, but cut was not sufficient to give me long lasting results. My second CRS did exactly what your CRS is suggesting and I had a LIS, 3 centenial tags removed, fissurectomy and skin- tag removal. With all of those cuts my recovery was not as fast as after simple LIS but it was manageable - NOTHING hurts like butt spasms and fresh fissure
- at least it was the case with me
Best wishes for your full and fast recovery !!!
