Doctors

Dr John Riley and Dr Philip Barnes are the two principals at Northern Gastroenterology. Other gastroenterologists visit on a part time basis.

Dr John Riley and Dr Philip Barnes are both Gastroenterologists. Gastroenterologists are physicians, with general training in internal medicine, and sub-specialty training in the field of Gastroenterology. This involves the whole of the gastrointestinal tract, from mouth to anus, and also includes the liver and pancreas and other digestive organs. Gastroenterologists are physicians, not surgeons. They do endoscopic procedures which is where the diagnosis of hiatus hernia, peptic ulcer, all sorts of gastrointestinal cancer, colitis, diverticulitis, haemorrhoids, etc can be made and arrange medical treatment. If surgery is required, Gastroenterologists arrange referral to Gastrointestinal surgeons who specialise in operative surgery.
