Background

The Division of Endocrine Surgery (ECS) is the only full-time surgical unit in Hong Kong that solely takes care of patients with a thyroid, parathyroid, adrenal or endocrine pancreatic problem. According to the annual Hospital Authority territory-wide audit (or SOMIP in short), our team has consistently been ranked as one of the highest volume endocrine surgical centers in the territory. Approximately 300 – 350 thyroid resections and 40 – 50 parathyroid resections are done annually by our team of surgeons. Apart from providing the highest standard of surgical care, our team has an immense interest in teaching & learning, research and clinical innovations.

Apart from teaching our own undergraduate medical students, the team has mentored many surgical trainees and overseas fellows interested in ECS. Through this fellowship program, many of our overseas fellows have become a leading surgeon in their respective country.

In research, one of the main focuses has been to gain a clearer understanding of the disease process in benign nodular disease (goiter), thyroid carcinoma, Graves’ disease, hyperparathyroidism, adrenal tumor, pancreatic neuroendocrine tumor and other less common endocrine familial syndromes. The division has been conducting clinically relevant and translational researches. Many of our research work have resulted in high-impact publications and presentations at international conferences allowing a greater dissemination of our experience.

The team has also been innovative in its treatment of various thyroid and endocrine-related diseases. For example, the team was the first in the territory to adapt robotic-assisted thyroidectomy. We were also the first in Asia to use high intensity focused ultrasound (HIFU) ablation in the treatment of symptomatic thyroid nodules. In surgical innovations, we were one of the early adaptors of the trans-oral vestibular thyroidectomy and the first to conduct a registered trial looking the safety of this approach.
