Lateral Internal Sphincterotomy (LIS)
Gold-standard surgery for chronic anal fissure — a small, controlled cut in the internal sphincter releases spasm and allows the fissure to heal completely with lasting relief.
What is Lateral Internal Sphincterotomy (LIS)?
Lateral Internal Sphincterotomy (LIS) is the gold-standard surgical treatment for chronic anal fissure that has not healed with conservative measures. A small, carefully controlled cut is made in the lower part of the internal sphincter muscle, releasing the spasm that prevents fissure healing. This restores normal blood flow to the area and allows complete healing of the fissure within weeks. As a female proctologist in Hyderabad, Dr. Tejasree Vengala performs LIS at Lux Hospitals, Hyderabad, with attention to careful technique and full continence preservation.
How the Procedure Works
Anaesthesia & Positioning
Surgery is performed under spinal or short general anaesthesia. The patient is positioned comfortably in lithotomy position.
Examination Under Anaesthesia
The fissure is examined fully, and the lower edge of the internal sphincter is identified using gentle digital examination.
Targeted Sphincterotomy
A small, controlled cut is made in the lateral internal sphincter through a tiny skin incision, releasing the muscle spasm.
Wound Closure
The small incision may be left open or closed with absorbable sutures, depending on the technique used.
Recovery & Discharge
Patients return home the same day with structured pain management, sitz baths, and dietary advice.

Chronic fissure pain is one of the most miserable experiences a patient can describe — sharp, burning, every single bowel movement. A precise, controlled sphincterotomy breaks that cycle within days. Patients often tell me they wish they had come in much sooner.
