✦ GOLD STANDARD FISSURE SURGERY

Lateral Internal Sphincterotomy (LIS)

Q: Will LIS affect my continence?

When performed correctly, LIS preserves continence in over 95% of patients. Only the lower portion of the internal sphincter is divided, leaving the external sphincter and the rest of the internal sphincter intact.

Q: Why do many women prefer a female proctologist for fissure?

Many women feel more comfortable discussing anorectal pain with a female doctor. As a female proctologist, Dr. Tejasree provides private, dignified, sensitive care, ensuring you feel at ease through every step.

Q: How long is the recovery?

Most patients return to office work within 3–5 days. Pain typically improves dramatically within the first week. Complete healing of the fissure takes 2–3 weeks.

Q: Will the fissure come back after LIS?

Recurrence is uncommon after a well-performed LIS — typically less than 5%. Maintaining a high-fibre diet, adequate hydration, regular exercise, and avoiding straining significantly reduce the risk.

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.

Suitable for adults with chronic anal fissure (more than 6–8 weeks duration) that has not healed with conservative measures such as high-fibre diet, stool softeners, sitz baths, and medical therapy with calcium channel blocker ointments.

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.
