Injection Treatment for Piles: What Patients Should Know

Haemorrhoids (piles) affect millions of people globally. For early-stage piles, injection sclerotherapy is a simple, effective, and well-tolerated non-surgical treatment.

What Is Injection Treatment (Sclerotherapy)?

Sclerotherapy involves injecting a chemical solution (typically 5% phenol in almond oil, or quinine/urea hydrochloride) directly into the haemorrhoidal tissue. The solution causes the blood vessels to harden, shrink, and eventually scar and disappear.

Who Is It Suitable For?

• Grade I haemorrhoids (bleeding without prolapse)
• Grade II haemorrhoids (prolapses but reduces spontaneously)
• Patients preferring a non-surgical approach
• Not suitable for Grade III/IV, thrombosed haemorrhoids, or skin tags

The Procedure

1. No anaesthesia required (the injection is into the insensitive mucosa above the dentate line)
2. Done as an outpatient procedure (no hospitalisation)
3. Takes 5–10 minutes
4. Up to 3 haemorrhoids can be treated at one session

What to Expect After Treatment

• Mild discomfort or a dull ache for 1–2 days
• Small amount of discharge or spotting
• Return to normal activity the same day
• Multiple sessions (usually 2–3) may be needed for complete resolution

Success Rate

Sclerotherapy is effective in 75–90% of Grade I–II cases. Recurrence is possible, especially if lifestyle factors are not addressed.

Lifestyle Changes to Complement Treatment

• High-fibre diet (fruits, vegetables, whole grains)
• Drink 2–3 litres of water daily
• Avoid straining during bowel movements
• Regular exercise
• Avoid prolonged sitting on the toilet
