Overview

Fissure surgery, typically known as lateral internal sphincterotomy, is a procedure performed to treat chronic anal fissures—small tears in the lining of the anus causing severe pain and discomfort. This surgery involves making a small cut in the anal sphincter muscle to reduce spasm, enhance blood flow, and promote healing. It is generally recommended when conservative treatments, such as dietary changes, medications, and topical ointments, fail to provide relief. The procedure is usually performed on an outpatient basis, offering fast recovery and long-term relief from symptoms.
