You have the right to choose where you have your NHS treatment.

At St Mary’s NHS Treatment Centre we offer free NHS treatments to all patients. You are not required to pay if you are an NHS patient and have been referred for treatment by your GP.

Excision of anal fissure

An anal fissure is a tear or open sore (ulcer) that develops in the lining of the anal canal. Surgical intervention may include a Lateral Sphincterotomy that involves making a small cut in the ring of muscle surrounding the anal canal (sphincter) to help reduce the tension in your anal canal. This allows the anal fissure to heal and reduces your chances of developing any more fissures.

Excision of anal lesions

Removal of an area of damaged tissue (lesion) by cutting it out.

Laying Open of Low Anal Fistula

A fistula can be described as narrow tunnel with its internal opening within the anal canal and its external opening in the skin near the anus. There are several options of treatment laying open of a fistula, which involves cutting the fistula open. Once the fistula has been laid open it will be packed on a daily basis for a short period of time to ensure the wound heals from the inside out.

Examination of rectum under General Anaesthetic

A rectal examination is a type of physical examination during which a doctor or nurse inserts a finger into your rectum (back passage) to feel for abnormalities. It is also known as a digital rectal examination.

Surgery for Haemorrhoids

Haemorrhoids (piles) are swollen blood vessels in or around the anus and rectum. There are various surgical interventions for haemorrhoids depending on the patient’s particular condition. This treatment is for external and severe haemorrhoids.


Incisions made in the tissue around the haemorrhoid. The swollen vein inside the haemorrhoid is tied off to prevent bleeding, and the haemorrhoid is removed.

Rubber band ligation

It is a procedure in which the haemorrhoid is tied off at its base with rubber bands, cutting off the blood flow to the haemorrhoid. This treatment is only for internal haemorrhoids.

Transanal haemorrhoid dearterialisation (THD)

It uses a Doppler (equipment used to measure blood flow) to locate the terminating branches of the haemorrhoidal arteries. Once the artery is located the surgeon uses an absorbable suture to ligate or “tie-off” the arterial blood flow. The venous “out flow” remains to “shrink” the pile.
