After surgical training in Hong Kong, he joined the then-nascent Department of Surgery at the Chinese University of Hong Kong. He learned endoscopy from the legendary Joseph Leung (Author photo 1), and together they established the world-renowned endoscopy unit at the Prince of Wales Hospital in Hong Kong, where numerous therapeutic techniques were pioneered. Dr Chung’s main research interest was ulcer bleeding. Much of our current practice in treating bleeding ulcers—for example, endoscopic injection therapy, high-dose intravenous acid inhibition, and eradication of Helicobacter species—is based on his original work. He was the first to perform laparoscopic cholecystectomy in Hong Kong (Author photos 2 and 3). He was appointed Professor of Surgery at the age of 39 and was elected Dean of the Faculty of Medicine in 1999. During his tenure as dean he revamped the undergraduate curriculum for medicine at the Chinese University. In 2004, he resigned from all of his positions in Hong Kong and moved to Port Moresby as Professor of Surgery at the University of Papua New Guinea (Author photo 4). Dr Chung recorded vignettes of his life as a medical student, a surgeon, and an educator (Author photo 5) in his book The Kindest Cut, which became a bestseller. These days, Sydney is popular as a motivational speaker and has difficulty dividing his time among spearfishing, paragliding, and learning to play the trumpet (Author photo 6).
