Profile
Dr Mathew Keegan is a Gastroenterologist and Advanced Interventional Endoscopist. He completed his medical degree at UNSW and advanced gastroenterology training at the Royal Prince Alfred and St George Hospitals. He undertook subspecialty fellowships in advanced endoscopy, IBD, as well as pancreatobiliary and luminal medicine and endoscopy under renowned experts at RPA, St James University Hospital in the UK, and Hopital Jean Mermoz in France. He later completed an observership at Hopital Erasme (Universite Libre de Bruxelles) in Belgium.
He is highly skilled in diagnostic and screening gastroscopy and colonoscopy; as well as advanced therapeutic endoscopy, including high-quality screening and surveillance for colorectal cancer, Barrett's oesophagus and pancreatobiliary disease; minimally invasive procedures to remove early cancerous and advanced precancerous growths found during screening (e.g. using ESD/EMR); and the management of complex pancreatic, biliary and small-bowel disorders using EUS, ERCP and balloon enteroscopy. He is passionate about using these techniques to offer prompt diagnosis and to optimise patient outcomes by offering minimally invasive options.
Dr Keegan is a member of several Australian and International professional societies and is accredited for gastroscopy, colonoscopy, ERCP and EUS by The Conjoint Committee for the Recognition of Training in Gastrointestinal Endoscopy. He is also a member of the WHO's FIDES Network and the World Gastroenterology Organisation's AI Taskforce.
Research
Dr Keegan's research interest is in improving diagnostic performance and patient outcomes in interventional endoscopy. His work includes the development and evaluation of artificial intelligence applications in endoscopy, strategies to optimise diagnosis and therapy in pancreatobiliary endoscopy, refinement of tissue resection techniques such as EMR and ESD, and initiatives aimed at quality improvement in endoscopic practice. In the past, he has presented various research in Australia, the United States and Europe, and his work has been published in international scientific journals, medical texts and specialist literature. His research integrates technological innovation, procedural optimisation and evidence-based practice to enhance accuracy, safety and patient care across diagnostic and therapeutic endoscopy.
