Lateral internal sphincterotomy is surgery to help heal an anal fissure that has not improved with medicine or other treatments. An anal fissure is a tear in the lining of the anus. During the surgery, the doctor puts a lighted tube called an anoscope, or scope into the anus. The doctor is able to see the inside of the anus through the scope. Special surgical tools are guided through the scope into the anus. The doctor uses the surgical tools to make a cut incision in the internal anal sphincter.

Lateral internal sphincterotomy - Wikipedia
A lateral internal sphincterotomy is a simple surgery during which the sphincter is cut or stretched. The sphincter is the circular group of muscles surrounding the anus that are responsible for controlling bowel movements. This type of sphincterotomy is a treatment for people who suffer from anal fissures. Anal fissures are breaks or tears in the skin of the anal canal. A sphincterotomy is used as a last resort for this condition, and people who experience anal fissures are usually encouraged to try a high-fiber diet, stool softeners, or Botox first. There are several other procedures that are often performed alongside a sphincterotomy.
