About Dr Balalis


During his General Surgery training in South Australia, he undertook a higher degree in Upper GI surgery, completing his Master of Philosophy (Surgery) in oesophageal cancer at The University of Adelaide. He continues to publish in peer-reviewed journals, and is a keen teacher with a position as a Clinical Lecturer at The University of Adelaide.

After completing surgical training in Adelaide, Dr Balalis was fortunate to have been selected for a competitive post fellowship position in Upper GI surgery with the Australia and New Zealand Gastric and Oesophageal Surgery Association (ANZGOSA) in 2018. He subsequently undertook sub-speciality training in prestigious and high-volume Upper GI and Bariatric surgery centres in Australia and internationally. Dr Balalis worked at The Alfred Hospital in Victoria, as the Upper GI and Bariatric Fellow. The Alfred Hospital has a strong background as a quaternary referral centre for revisional obesity surgery. He then worked in the United Kingdom (UK) at Nottingham University Hospital (NUH) NHS Trust, as the post-CCT Senior Clinical Upper GI Fellow. This is one of the largest Upper GI surgery units in all of Europe and the UK, and has an outstanding record for excellence in Upper GI surgery, particularly in cancer operations. Dr Balalis was fortunate to receive a Royal Australasian College of Surgeons (RACS) Travelling Fellowship for this opportunity.

During his sub-specialty fellowship Dr Balalis trained in other world-renowned surgical units, including University Medical Centre (UMC) Utrecht in the Netherlands, which are some of the pioneers of Robotic Upper GI surgery. Dr Balalis then undertook further training in obesity surgery at The Royal Brisbane and Women’s Hospital in Queensland. This training has provided Dr Balalis with the necessary skills and know-how to provide you with the best care.

He is active with professional societies and audit including ANZGOSA (Australian and New Zealand Gastro-oesophageal Surgical Association), ANZMOSS (Australian and New Zealand Metabolic and Obesity Surgical Society), IFSO (International Federation for the Surgery of Obesity and Metabolic Disorders) and RACS (Royal Australasian College of Surgeons). He also regularly attends national and international meetings, as he believes it is important to stay up to date. Dr Balalis has recently received a further RACS Travel Scholarship which will enable him to return to the Netherlands to continue training in robotic oesophageal surgery.

Dr Balalis is a very proud husband and father of two boys. If he is not seeing patients or operating, he is playing tennis or enjoying some down time with family and friends.
