Lateral Sphincterotomy

Lateral internal sphincterotomy is the treatment of choice for anal fissures. A little tear in the sensitive, moist tissue that lines the anus is known as an anal fissure. Anal fissures, which commonly occur during and after a bowel movement, are brought on by the spasm of the anal muscles and can result in anal pain that can be pretty severe. For patients with chronic anal fissures, lateral internal sphincterotomy is the preferred surgical approach. It has a lower rate of adverse events than older methods and has no change in fecal continence.
