Dr Mani Niazi has demonstrated a sustained interest in surgical innovation, with a particular focus on the early development and clinical introduction of Laparoscopic Gastric Plication during his training and early consultant career. His work reflects a long-standing commitment to advancing minimally invasive bariatric surgery and improving patient outcomes.
In 2010, during an observational visit to the Royal Brisbane Hospital, Dr Niazi introduced Gastric Plication to the bariatric surgical team and was involved in the supervision of its first procedure performed in Australia by a leading upper gastrointestinal surgeon. In recognition of his contribution, he was awarded a travelling fellowship by the Upper Gastrointestinal Surgery Unit at Royal Brisbane Hospital.
In 2011, he was invited to present at the first international summit on Gastric Plication in Barcelona, reflecting his early involvement in the global academic discussion and adoption of this procedure.
His early clinical experience and case series in Gastric Plication were subsequently cited in Schwartz’s Principles of Surgery (10th edition, 2014–2015), one of the world’s most authoritative surgical textbooks.
Dr Niazi has undertaken advanced surgical training across internationally recognised centres of excellence, building a broad and highly refined clinical foundation across general, upper gastrointestinal, and subspecialty surgical practice.
Trained at Tehran University of Medical Sciences, where he developed a strong grounding in core surgical principles and clinical practice.
