Fissure Treatment
Sphincterotomy (LIS)
Lateral internal sphincterotomy (LIS) is the gold standard surgical treatment for chronic anal fissures. At Apollo Clinic in Bangalore, Dr. Adarsh performs a controlled division of the lower portion of the internal anal sphincter to reduce resting anal pressure, allowing the fissure to heal permanently. The procedure takes under 15 minutes and has a cure rate exceeding 95 percent.
About Sphincterotomy (LIS)
Lateral internal sphincterotomy (LIS) is the gold standard surgical treatment for chronic anal fissures that have not healed with conservative measures. The procedure involves a small controlled division of the lower portion of the internal anal sphincter muscle, relieving the spasm that prevents fissure healing. Dr. Adarsh performs this through a tiny lateral incision with precise technique to minimize any impact on continence.
