THD® Doppler Method: what is it?

Today medical research and technological progress have made available a minimally invasive surgical method for the treatment of haemorrhoids: the THD® Doppler Method.

The THD® Doppler Method is an innovative surgical procedure which allows treating the symptoms of haemorrhoidal disease while preserving the anatomy of the anorectal canal.

The surgeon reduces the terminal vessels of the artery that feeds the haemorrhoids, without removing any tissue. Thus, it is possible to reduce the excessive flow of blood without painful incisions for the patient. Furthermore, this ligation takes place in an area which is less sensitive to pain, allowing to further reduce the discomfort of the operation.

After tying the terminal branches of the rectal artery, the surgeon repositions the haemorrhoidal cushions in their natural seat.

In this way it is possible to effectively treat the causes which have induced the symptoms of haemorrhoidal disease.


THD® Doppler procedure: how is it performed?

The surgeon performs the THD® Doppler procedure by means of a proctoscope equipped with a special Doppler probe. The Doppler signal allows the surgeon to locate the arterial vessels with precision and subsequently to reduce the blood overflow by a simple ligation with surgical suture.

If the haemorrhoidal cushions are prolapsed outside, after ligation, the surgeon may perform a mucopexy, thus allowing the haemorrhoidal tissue to be repositioned in its original position.

The entire procedure is performed in an area with few pain receptors and lasts about 30 minutes. A haemorrhoid operation with this method does not normally require hospitalisation and can also take place in day hospital.


When is the operation necessary?

There are several ways to treat haemorrhoids, but in the most severe cases it is often necessary to resort to surgery.

Based on clinical evidence, the THD Doppler procedure is effective for all the different grades of the haemorrhoidal disease and in the presence of prolapse. The THD haemorrhoid surgery is generally indicated for the treatment of internal haemorrhoids which do not respond to conservative therapy or topical treatment.

In any case, only the proctologist surgeon during the rectal examination will be able to assess whether there are the conditions for surgery.


Before and after surgery


The operation involves the anal canal and the lower part of the rectum: this is why the surgeon may prescribe one or two enemas before the operation. Antibiotics are not normally required.


After surgery, most patients experience a noticeable reduction in pain.

However, the patient may feel a sensation of discomfort in the treated area, a sensation which normally tends to disappear in a few days. If necessary, the surgeon can prescribe common painkillers to help the patient keep this discomfort under control. Immediately after the operation, minor bleeding may also occur; this generally resolves after a few hours.

Another temporary condition which could occur is the urge to evacuate, even in the absence of faeces (tenesmus); this sensation is linked to the repair of the haemorrhoidal prolapse.

In most cases, the THD® Doppler method can be considered a permanent solution: recurrences are in fact described in the literature as limited.


THD® Doppler operation: advantages

The THD® Doppler method offers many advantages, in particular:

  • respect of the anatomy of the anorectal region.
  • minimum pain and discomfort both during and after surgery.
  • rapid recovery and a fast return to usual activities.
  • limited relapses.
  • effective results both on the causes and on the symptoms of the haemorrhoidal disease.

Where can I find the THD® Doppler Method?

The THD® Doppler method is used in many medical centres and hospitals around the world.
