Lateral Sphincterotomy

About the Treatment

Lateral internal sphincterotomy is the most effective surgery for chronic anal fissure that has not healed with ointments, botulinum toxin or clinical measures. It involves a small, controlled cut in the lower portion of the internal anal sphincter, reducing the excessive pressure that keeps the wound open and allowing it to heal over the following weeks. It is a brief procedure, performed under anesthesia in a surgical setting, with same-day discharge and pain relief usually within the first few days. At Femi Saúde, the coloproctology team reserves sphincterotomy for carefully selected cases, evaluates sphincter function beforehand, especially in women with a history of childbirth, and monitors recovery until healing.
