Anal Fissure Surgery

About Anal Fissure Surgery

Doctors at AarPee Hospital recommend a surgical procedure called partial lateral internal sphincterotomy as the technique of choice for the treatment of anal fissures. In this procedure, the internal anal sphincter is cut starting at its distal most end at the anal verge and extending into the anal canal for a distance equal to that of the fissure. The cut may extend to the dentate line, but not farther. The sphincter can be divided in a closed (percutaneous) fashion by tunneling under the anoderm or in an open fashion by cutting through the anoderm.

The cut is made on the left or right side of the anus, hence the name "partial lateral internal sphincterotomy." The posterior midline, where the fissure usually is located, is avoided for fear of accentuating the posterior weakness of the muscle surrounding the anal canal. Additional weakness posteriorly can lead to what is called a keyhole deformity, so called because the resulting anal canal resembles an old fashioned skeleton key. This deformity promotes soilage and leakage of stool. Since the doctors at AarPee have been performing such surgeries since many years, there is a surety of a safe and successful surgery.
