Lateral Internal Sphincterotomy (LIS)
The gold-standard surgical treatment for chronic anal fissure - a small, precisely controlled incision in the internal anal sphincter relieves spasm, restores blood flow, and allows complete healing. Best fissure doctor in Hyderabad at Lux Hospitals.
What is Lateral Internal Sphincterotomy (LIS)?
Lateral Internal Sphincterotomy (LIS) is the gold-standard surgical treatment for chronic anal fissure. The procedure involves a small, precisely controlled incision in the lower portion of the internal anal sphincter - the hypertonic muscle whose spasm causes the pain cycle and poor blood supply preventing healing.
By releasing the sphincter spasm, LIS immediately relieves pain, restores blood flow, and allows the fissure to heal rapidly. Dr. Samhitha Reddy, one of the best fissure doctors in Hyderabad, performs LIS at Lux Hospitals using a lateral approach that minimises incontinence risk while achieving complete therapeutic effect. It is the most recommended fissure surgery in Hyderabad for chronic disease.
LIS is indicated for chronic anal fissures (>6 weeks) that have failed conservative treatment with topical GTN, diltiazem cream, or Botox injection. Acute fissures are managed conservatively first.
How the Procedure Works
Assessment
Dr. Samhitha confirms chronic status (>6 weeks). Resting anal pressure is assessed. Surgery planned as a day-care procedure.
Anaesthesia
Short spinal or general anaesthesia. Lithotomy position. Peri-anal local anaesthetic infiltration for additional post-operative analgesia.
Lateral Incision
A small 1–1.5 cm incision is made laterally (3 or 9 o'clock) - the lateral approach avoids the posterior midline and minimises keyhole deformity risk.
Sphincterotomy
The lower fibres of the internal anal sphincter are divided under direct vision to the level of the fissure apex - precisely controlled division, no more.
Wound Closure & Recovery
The small lateral incision is closed with a single absorbable suture. Discharged within a few hours. Dramatic pain relief within 24 hours of surgery.
