Botox Injection for Anal Fissure
An anal fissure is a tear in the tissue lining the anus, and is associated with pain and bleeding during bowel movements. It can occur because of trauma or injury to the anal canal while passing hard or large stools, constipation, or straining during bowel movements or childbirth. Sometimes, excess stress on the two muscular sphincters (rings) that control the anus can reduce blood supply and lead to the development of anal fissure.
Botox injection may be prescribed to treat an anal fissure. Botox is a drug derived from a bacterium that temporarily paralyses your internal anal sphincter muscles. When injected, it helps to reduce discomfort, relaxes the sphincter muscles of the anus, improves blood circulation and allows the fissure to heal.
The procedure is performed on an outpatient basis under local anaesthesia. Your doctor directly injects Botox into the muscles of the internal anal sphincter.
As with any procedure, Botox injection may involve certain risks and complications such as anal bleeding, infection and pain at the injection site, inability to control the passage of gas and faeces.
