Description of Service

The Wolfson Unit for Endoscopy at St Mark’s is world renowned, being the only unit in the UK to achieve international recognition as a centre of excellence for endoscopy research and training. It was also the first unit in London to be accredited as a Bowel Cancer Screening centre in 2006 and is currently one of only six pilot sites in the UK for the Bowel Scope Screening programme, delivering the national bowel cancer screening programmes to the local population. The Wolfson Unit has also developed regional and national referral services for polypectomy, video capsule endoscopy and double-balloon enteroscopy, and provides nationally accredited courses for the teaching and training of endoscopists.

The Wolfson unit has six procedure rooms with state-of-the-art equipment and provides endoscopy services for both St Mark’s and Northwick Park Hospital. Together with a smaller, two-room unit at Central Middlesex hospital around 18,000 endoscopies are performed per year. A full range of therapeutic procedures are performed in the unit, and cutting edge instruments and accessories combined with specialist endoscopy doctors and nurses allow us to ‘reach the parts other doctors cannot reach’ – comfortably and safely. We pride ourselves in making things easy for our patients, whether unwell or visiting for ‘well patient’ screening.

What is Endoscopy?

An endoscopic procedure allows the doctor or nurse to visually inspect your gastrointestinal tract using a video camera attached to the end of a long thin flexible tube. Upper Gastrointestinal Endoscopy (also known as OGD or Gastroscopy) includes examination of the oesophagus (food pipe or gullet), stomach and duodenum (the first part of the small bowel). Lower Gastrointestinal Endoscopy (colonoscopy or flexible sigmoidoscopy) is an examination of the colon (large bowel). We are also able to visualise the entire small bowel using either an easily swallowed pill-sized camera (video capsule endoscopy) or specialist endoscopic equipment designed to navigate the small bowel (double-balloon enteroscopy).

The National Bowel Cancer Screening Programme:

Bowel cancer (also known as colorectal cancer) is the second most common cause of cancer deaths in the UK, with 41,581 new cases diagnosed in 2011 accounting for 13% of all new cancers. The lifetime risk of developing bowel cancer in the UK is 1 in 14 for men and 1 in 19 for women. To read more about bowel cancer and its treatment, please visit the Cancer Research UK website by clicking here.

Colorectal cancer can be prevented via polypectomy, which is the removal of pre-cancerous growths (polyps) within the bowel at either colonoscopy or flexible sigmoidoscopy. This is a safe, mostly painless procedure with highly effective results.

Meet the Team

Between 30-40 physicians, surgeons and nurses deliver endoscopy cross-site at St Mark’s and Central Middlesex Hospitals. The Wolfson unit, however, has a core team of clinicians and nurses who specialise in endoscopy and deliver services to local and tertiary patients. They are supported by a large team of specialist nurses, endoscopy assistants and technical staff.
