Thermotherapy (warm) or cryotherapy (cold) dilators may be used for differing pathologies.


The small and medium-sized dilators are to assist in progressive distension in the presence of various anal stenoses. The large size is always indicated for spasm.

In many pathologies, the temperature of the dilator is not important.

However, for the following conditions the dilator should be used warm, up to but not exceeding 50° Celsius:

  • Stenosis (contraction) of the anus, due to cicatricial or idiopathic origin
  • Holds 5mm and 10mm laparoscopes
  • Prevention of post-operative stenosis due to haemorrhoids or fistulas

For the following conditions, the dilator should be cooled to not below 0° Celsius:

  • Anal bleeding

Prior to insertion, the dilator should be covered in a layer of Dilatan cream. Sitting in the bidet or lying on the bed, insert the dilator slowly up to its base. Keep it in position for two to three minutes, and then pull it slowly out. It is advisable not to stand or walk with the dilator in position.

  • Following haemorrhoidectomy, dilations should be performed once or twice daily for the first month, reducing to three times a week for the second and third months. This will greatly relieve post-operative discomfort.
  • In cases of anal stenosis, twice-daily use of the dilator is advisable. Treatment should be continued for several months.
  • For other conditions, Dilatan should be used twice a day whilst symptoms persist, and the treatment continued for at least a month after the symptoms have ceased.

For thermotherapy, the dilator should be immersed in warm water, ideally at 50° Celsius, for 10-15 minutes.

For cryotherapy, the dilator should be immersed in iced water for 15 minutes in the fridge.

The Dilatan works well regardless of whether the lower bowel is full or empty. In case of spasm, sitting in a warm water bidet prior to insertion will help relax the sphincter muscles and assist the therapy.

Cleaning Dilatan

Following use, the dilators should be washed in warm, soapy water, thoroughly rinsed and returned to the box when clean and dry.
