A variety of endoscopic procedures are carried out within the unit including:

  • Diagnostic and therapeutic gastroscopy (for looking inside the gullet and stomach)
  • Colonoscopy (for looking inside the colon)
  • Flexible sigmoidoscopy (for looking inside the bowel)
  • Bronchoscopy (looking inside airways and lungs)
  • ERCP (endoscopic retrograde cholangio-pancreatography)

We also perform colonoscopies for the National Bowel Cancer Screening Programme (BCSP) which aims to detect the early signs of bowel cancer.

What you can expect

An endoscopy is a procedure where the inside of your body is examined internally using an endoscope.

The procedure is often undertaken while a person is awake and a sedative (medication that has a calming effect) may be given to help the patient relax.

The endoscope itself is a flexible tube with a video chip on the end which allows a live video image to be seen on a screen.

Endoscopes can be inserted into the body through your throat or anus, or through a small incision (cut) made in the skin.
