In my family history no one is patient of anal fissure. But I get anal fissure easily for one time hard stool though I rarely get hard stool within 2 -3 years one time . But this too leads anal fissure . So , consultation with a colorectal surgeon LIS surgery was done to eradicate the tendency of getting fissure. But 3 years after surgery again I have developed anal fissure . So has any other surgery other than LIS to cure anal fissure ???
