Patients may present with abdominal pain, reflux, difficulty swallowing, altered bowel habits, bleeding, jaundice or symptoms of inflammatory bowel disease. Evaluation uses medical history, examination and laboratory or imaging tests, followed when appropriate by gastroscopy, colonoscopy, sigmoidoscopy or ERCP. Treatment pathways can include medication and dietary guidance, endoscopic haemostasis, dilatation, polyp removal, banding, stenting or referral for surgery. The department aims to identify the source of symptoms accurately, treat disease effectively and protect digestive health over the long term.
