Anal sphincterotomy
Anal Sphincterotomy
Anal sphincterotomy (pronunciation: /ˈænəl sfɪŋkˈtɛrətəmi/) is a surgical procedure performed to treat anal fissures. The term is derived from the Greek words "sphincter," meaning "band" or "ligature," and "tome," meaning "a cutting."
Definition
An anal sphincterotomy involves the surgical division or partial division of the internal anal sphincter muscle. This procedure is typically performed to alleviate the symptoms of an anal fissure, which is a small tear in the thin, moist tissue (mucosa) that lines the anus.
Procedure
The procedure is usually performed under general anesthesia. The surgeon makes a small incision in the skin around the anus to access the internal anal sphincter. The muscle is then partially divided to reduce tension and promote healing of the anal fissure.
Risks and Complications
As with any surgical procedure, anal sphincterotomy carries some risks. These may include bleeding, infection, and incontinence. However, the procedure is generally considered safe and effective for the treatment of anal fissures.
