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.


Anal fissures result from dry, hard stool or a series of loose bowel movements that tear the inner lining of your anus. 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.


Your doctor might be able to see external hemorrhoids. Diagnosing internal hemorrhoids might include examination of your anal canal and rectum.

  • Digital examination
  • Visual inspection


Treatment of anal fistula depends on the fistula's location and complexity. The goals are to repair the anal fistula completely to prevent recurrence and to protect the sphincter muscles. Damage to these muscles can lead to fecal incontinence.The options include:

  • Fistulotomy
  • Advancement rectal flap
  • Seton placement
  • Fibrin glue and collagen plug
  • Ligation of the intersphincteric fistula tract
