About
Dr. Mathew Keegan is a highly skilled Gastroenterologist, Advanced Interventional Endoscopist, and Pancreaticobiliary Specialist. He is dedicated to providing compassionate and high-quality care, and strives for the best outcomes for his patients. Dr. Keegan is a visiting medical officer at North Shore Private Hospital and Northern Beaches Hospital. He provides high quality screening and advanced endoscopic and minimally invasive therapeutic procedures across these sites, as well as local day surgeries (Pittwater Day Surgery and Dee Why Endoscopy).
With expertise in advanced diagnostic and screening gastroscopy and colonoscopy, Dr. Keegan also excels in advanced therapeutic endoscopic procedures and biliary and small bowel care/procedures. He advocates for minimally invasive advanced techniques to minimise disruption to patients' normal lives, particularly supporting screening programs for bowel or colorectal cancer.
Dr. Keegan completed his training in Sydney Royal Prince Alfred and St George Hospitals, followed by subspecialty training in pancreaticobiliary medicine, inflammatory bowel disease, and minimally invasive endoscopic management of digestive tract, pancreatic, and biliary conditions at esteemed institutions such as St James University Hospital in the United Kingdom, Hôpital Jean Mermoz in France, and more recently the Erasmus Hopsital in Belgium.
His special interests include advanced diagnostic and therapeutic endoscopic procedures, such as screening for colon cancer and Barrett's esophagus, specialised procedures for non-surgical, outpatient management of early gut cancers, and advanced precancerous growths, and management of pancreatic, biliary, and small bowel disorders using EUS, ERCP, and balloon enteroscopy.
Dr. Keegan's research has focused on improving the diagnostic performance and patient outcomes of existing endoscopic techniques. He has presented his findings in Australia, the USA, and Europe and has been published in international scientific journals and medical texts.
Dr Keegan has medical and endoscopic expertise in the management of a broad range of condition affecting the oesophagus, stomach, small bowel, colon and rectum, pancreas, bile ducts and gall bladder, and liver including:
• Bowel cancer screening

• Irritable bowel syndrome
• Inflammatory bowel disease
• Ulcers
• Pancreatic cancer diagnosis and screening

He has years of experience, both in Australia and internationally, in the following diagnostic and advanced minimally invasive endoscopic procedures:
• Diagnostic and screening gastroscopy/endoscopy
• Diagnostic and screening colonoscopy
• Endoscopic/non-surgical management of early/superficial cancers and large precancerous growths in the colon and rectum (large bowel)
• Endoscopic management of Barrett's oesophagus and early oesophageal cancer
• Endoscopic management of early gastric cancer and pre-cancerous lesions of the duodenum (upper small bowel)
• Diagnostic and screening endoscopic ultrasound (EUS) for assessment of oesopahgeal, gastric, duodenal, pancreatic, biliary, and coloretcal conditions
• Endoscopic ultrasound (EUS)-guided minimally invasive therapeutic procedures within the abdomen and pelvis
• Endoscopic retrograde cholangiopancreatography (ERCP) for treatment of bile duct, liver, and pancreatic disease
• Diagnostic and theraptic cholangioscopy and pancreatoscopy (miniaturised high-resolution endoscopy inside the bile duct and pancreatic duct)
• Deep/device-assisted enteroscopy, an option for managing some small bowel conditions, including bleeding, without requiring abdominal surgery
A member of several Australian and international professional societies, Dr. Keegan is accredited for gastroscopy, colonoscopy, ERCP, and EUS by the Conjoint Committee for the Recognition of Training in Gastrointestinal Endoscopy and maintains 3-yearly recertification in colonoscopy.
