Endoscopic procedures that are required will be performed by Dr Lewis, who will discuss them in detail before proceeding. He will often be able to tell you the results immediately, although it may take up to two weeks for the results of biopsies.
An OGD (‘Gastroscopy’) examines the oesophagus, stomach and duodenum. The endoscope is passed through the mouth. Usually, the procedure is carried out after numbing the back of the throat with local anaesthetic spray, or with intravenous sedation.
This test involves passing the endoscope through the back passage. A colonoscopy examines the whole colon (large intestine, or bowel) and is normally carried out under intravenous sedation. Bowel preparation is required with laxatives beforehand. A colonoscopy can be uncomfortable so we offer Entonox (nitrous oxide) or intravenous sedation during the procedure. Flexible Sigmoidoscopy examines only the lower part of the colon.
