I have annal fissure for a year now. Tried Botox,using nitroglycerin, eating plenty of vegitable fruits and taking miralax and senna. Every two months same fissure acts up pain bleeding then heal and comes back with just a little (dry or hard stool) even after I watch what I eat. Want to do LIS surgery but very scared about incontinence. I just want my life back. Can anybody share about LIS surgery experience and how successfull it is?
