Lateral Sphincterotomy
A lateral internal sphincterotomy is a surgery that repairs an anal fissure. It helps reduce pressure inside the anus that can cause spasms and increases blood flow to the area to help the tissue heal.
Causes

Some people have tighter sphincter muscles, putting them at a higher risk of developing anal fissures. Other causes including inflammatory bowel disease, trauma, anal infections, and tumors. They're often confused with other anal conditions, like hemorrhoids.
