Laser Surgery for Fistula: How It Works

Laser fistula surgery is a minimally invasive technique used to treat anal fistulas—abnormal tunnels connecting the anal canal to surrounding skin. Unlike traditional fistulotomy, laser treatment preserves the sphincter muscles and offers faster healing with less pain.

How Laser Fistula Surgery Works

1. Preoperative Evaluation

   • MRI or ultrasound to map fistula tract

   • Clinical exam under anesthesia to identify internal opening

     
     

2. Procedure

   • Performed under spinal or local anesthesia

   • A thin fiber-optic laser probe is inserted into the external opening and advanced to the internal opening.

   • Radial laser energy is delivered as the probe is gradually withdrawn, shrinking and sealing the tract epithelium from inside out.

   • Closure of internal opening using a small endorectal flap or suture

     
     

3. Benefits

   • Sphincter-saving: Low risk of incontinence

   • Minimal external wound: Tiny puncture, almost no scar

   • Less postoperative pain and bleeding

   • Short procedure time (30–60 minutes)

   • Day-care surgery: Return home same or next day

     
     

4. Recovery

   • Resume light activities within 2–3 days

   • Full healing in 4–6 weeks in most simple fistulas

   • Low complication rates; primary success ~68%, secondary ~80% at 2 years

   • Follow-up at 1 week, 1 month, and 6 months
