Colorectal surgery


St Mark's Hospital is the country's leading specialist hospital for colorectal and intestinal disease. 

We manage many different types of patients including major surgery, intestinal failure, stoma care, polyposis and irritable bowel disease.  We support patients with continence issues using physiology, biofeedback and sacral nerve stimulation. Specialist radiolgical investigation and advanced endoscopy are also available.

As one of the four core hospitals comprising the London North West Healthcare NHS Trust, all patients referred to the Trust benefit form the high quality and leading edge care provided by specialists at St Mark's. We see all types of problems ranging from haemorrhoids to major bowel resection and intestinal failure. All gastro-intestinal services are co-ordinated through the St Mark's division, including access to endoscopy and upper GI clinics. We have a service providing both direct access to local GPs and a tertiary centre for more complex patients, including patients with suspected cancer.
