Laser Surgery for Piles, Fissure & Fistula
Precise, low-pain laser treatment for piles, fissure, fistula and pilonidal sinus — usually as day-care surgery.
Laser proctology uses a fine laser fibre to treat anorectal conditions such as piles, anal fissure, anal fistula and pilonidal sinus through tiny openings, without large cuts or stitches. Because it is precise and tissue-sparing, patients typically have far less pain, minimal bleeding, day-care surgery and a quick return to normal life.
Many people put off treatment for piles, fissures and fistulas because they fear a painful operation and a long recovery. Laser proctology has changed that experience. Using focused laser energy delivered through a thin fibre, Dr. Sujan Shrestha treats these common anorectal problems with pin-point precision, little pain and small wounds — most often as day-care surgery, so patients can return home and to their routine quickly.

Overview
Laser proctology is a group of minimally invasive procedures that use a fine laser fibre to treat conditions in and around the anus. Instead of cutting away tissue with a blade and leaving open wounds, the laser delivers precise energy that shrinks and seals swollen pile tissue, promotes healing of a chronic fissure, closes a fistula tract, or cleans and seals a pilonidal sinus.
Because the laser is so targeted, it spares the surrounding healthy tissue and the important sphincter muscle, causes very little bleeding, and usually avoids the large cuts and stitches of traditional surgery. This is why laser treatment is associated with less post-operative pain and a faster recovery.
Conditions it treats
- Piles / hemorrhoids (laser hemorrhoidoplasty)
- Chronic or recurrent anal fissure
- Anal fistula (laser closure — FiLaC)
- Pilonidal sinus (laser sinus ablation)
- Selected patients seeking a low-pain, day-care option
Key benefits
- Minimally invasive — no large cuts or open wounds in most cases
- Significantly less post-operative pain
- Minimal bleeding thanks to the sealing effect of the laser
- Sphincter-sparing, protecting normal bowel control
- Usually day-care surgery with a quick discharge
- Faster return to work and daily activities
- Small or barely visible scars
How the procedure is performed
Laser proctology is usually done under short general or regional (spinal) anaesthesia, so you feel nothing during the procedure. After positioning and gentle examination, a thin laser fibre is introduced through a tiny opening or the anal canal, guided precisely to the target tissue.
The technique is tailored to the condition: for piles, laser energy is applied to shrink and seal the swollen tissue from within; for a chronic fissure, it helps relieve spasm and encourage healing; for a fistula, the fibre seals the tract along its length (FiLaC); and for a pilonidal sinus, it cleans and closes the tunnel. Most procedures take around 20 to 45 minutes, and because there are no large incisions, stitches are usually not needed in the sensitive skin.
Preparing for surgery
Before surgery you will have a consultation and examination to confirm the diagnosis and grade or map the condition — for a fistula this may include an MRI or ultrasound. Routine blood tests and anaesthetic checks are done, and you will be asked to fast for about six hours beforehand. Tell the surgeon about all medicines you take, especially blood thinners, and about diabetes or other health conditions. A gentle bowel preparation or enema may be advised.
Recovery & aftercare
Most patients go home the same day. Pain is usually mild and well controlled with simple painkillers, and any spotting or discharge settles over a short period. You will be advised to keep stools soft with a high-fibre diet and plenty of fluids, take warm sitz baths, and keep the area clean. Many people return to desk work within a few days, with full healing over one to three weeks depending on the condition treated. Follow-up is important, as fistulas and pilonidal sinuses sometimes need review or staged care.
Risks & considerations
- Mild pain, spotting or discharge for a short time after surgery
- Temporary difficulty or discomfort passing stool
- Recurrence of the condition, especially with complex fistulas
- Local infection (uncommon) needing antibiotics
- Rarely, narrowing of the anal opening or need for a further procedure
- Small chance that conventional surgery is more suitable in some cases
Frequently asked questions
Laser is commonly used for piles, chronic anal fissure, anal fistula and pilonidal sinus. Not every case is suitable for laser alone, so Dr. Sujan Shrestha assesses each patient and recommends the best technique for a lasting cure.
Yes. Because laser treatment avoids large cuts and stitches in the sensitive anal skin and seals tissue as it works, most patients experience much less pain than with traditional open surgery, usually needing only simple painkillers.
Laser techniques are designed to spare the sphincter muscle, which helps protect normal bowel control. For fistulas, careful mapping and sphincter-sparing methods such as FiLaC are chosen specifically to keep continence safe.
In most cases, yes. Laser treatment is commonly performed as day-care surgery, meaning you come in, have the procedure, and usually go home the same day to recover comfortably at home.
Many patients resume light activities and desk work within a few days because of the low pain and small wounds. Full healing takes one to three weeks depending on the condition, and your surgeon will guide your return to heavier activity.
