What is sclerotherapy for piles?

Sclerotherapy for piles is a medical procedure used to treat internal haemorrhoids. The chemical solution is injected into the affected area during the procedure. This solution causes the piles to shrink and eventually disappear.

This is done by creating scar tissue, which inhibits the blood supply to the haemorrhoid. Sclerotherapy is recommended for smaller internal piles and is often performed in an outpatient setting.

Conditions Treated with Sclerotherapy for Piles

Injection sclerotherapy is primarily used to treat grade 1 (no prolapse outside the anal canal meaning swollen veins protrude outside the body) and grade 2 (piles mass bulge outside the anal opening) haemorrhoids. It offers relief from symptoms such as bleeding and discomfort. 

The method is effective for smaller internal piles that have not responded to conservative treatments. These may include dietary changes and over-the-counter medications.

Sclerotherapy Piles Treatment

Sclerotherapy for piles is a straightforward procedure, lasting no longer than 10 to 15 minutes. This highlights the efficiency of this treatment in targeting internal haemorrhoids with precision. The key steps involved are:

  1. Preparation: The patient will be rested comfortably in a supine position on the examination table. 

  2. Injection: The doctor injects a sclerosing agent (chemical solution) into the hemorrhoidal tissue using a fine needle. 

  3. After Effects: The solution will cause inflammation and scarring, leading to the shrinkage of the piles over time. It takes around 4 to 6 weeks.

After Surgery and Recovery

Sclerotherapy for piles typically takes 1-2 weeks to treat haemorrhoids. One may expect the following during their recovery period:

The Recovery Process in Hospital 

As sclerotherapy for piles is an outpatient procedure, patients can usually leave the medical facility on the same day as the treatment. The factors one may expect in the hospital immediately after the surgery are:

  1. Vital signs, like blood pressure, pulse rate, and body temperature, are checked.

  2. Pain management medications are provided. 

  3. Patients are monitored till they urinate and pass gas or stools to ensure the effectiveness of treatment.

Recovery Process/Expectation After Hospital Discharge 

After hospital discharge, the patient may experience mild discomfort, bleeding, or irritation around the anal area for a day. The guidelines below may help to cope with these complications:

  1. Follow a soft diet and drink plenty of fluids

  2. Take painkillers as prescribed by the doctor

  3. Avoid strenuous activities for a day or two

  4. Contact the doctor if experiencing severe pain and persistent bleeding

First Follow-Up Appointment

During this appointment, the doctor evaluates the effectiveness of the sclerotherapy treatment. They will assess the patient's overall recovery and inquire about residual symptoms.
