About

Ms Yi Sia is an enthusiastic endocrine and general surgeon who focuses on patient-centred care. After obtaining her Fellowship with the Royal Australasian College of Surgeons at the beginning of 2019, she undertook two fellowships in endocrine and general surgery at Western Health and Northern Health in Melbourne.

She subsequently relocated to Oxford, UK for a third fellowship with the Endocrine Surgical Unit at Oxford University Hospitals, under the guidance and mentorship of Mr Radu Mihai, an eminent endocrine surgeon in the UK and Europe.
It was at Oxford that she developed a keen interest in thyroidectomy for large retrosternal goitres, lateral neck dissection and retroperitoneoscopic adrenalectomy.

In addition to endocrine surgery, Yi performs general surgery, such as gallbladder and hernia surgery, as well as emergency general surgery.

Common Procedures

The thyroid gland is a butterfly-shaped gland located at the front of your neck that produces thyroid hormones responsible for regulating many of the body’s functions.
Thyroidectomy may need to be performed for symptomatic thyroid nodules or goitre, Graves’ disease, or cancer.

Ms Yi Sia Parathyroid Procedure Endocrine General Surgeon East Melbourne Werribee AustraliaMs Yi Sia Endocrine General Surgeon North West East Melbourne Australia Public Private Appointments

In most people, there are four parathyroid glands about the size of a grain of rice intimately associated with the back of the thyroid gland. These glands secrete parathyroid hormone (PTH) that regulates calcium levels in the blood.
When one or more of these glands become enlarged, too much PTH is produced leading to high calcium levels in the blood. Surgery involves removing the overactive gland(s).

Ms Yi Sia Gall Bladder Procedure Endocrine General Surgeon East Melbourne Werribee AustraliaMs Yi Sia Endocrine General Surgeon North West East Melbourne Australia Public Private Appointments

The gallbladder is a pear-shaped organ that sits under the liver and is responsible for storing and releasing bile, which helps digest fats.
The most common disorder affecting the gallbladder is the formation of gallstones, which can lead to symptoms (biliary colic) and potential complications such as cholecystitis (inflammation of the gallbladder), cholangitis (inflammation of the bile duct) and pancreatitis (inflammation of the pancreas).

The adrenal glands sit above the kidneys and produce important hormones that regulate metabolism, blood pressure, and the body’s response to stress.
Occasionally, operation to remove the adrenal gland is necessary if there is an adrenal nodule that produces excess hormones, or if a malignancy is suspected.

Ms Yi Sia Hernia Procedure Endocrine General Surgeon East Melbourne Werribee AustraliaMs Yi Sia Endocrine General Surgeon North West East Melbourne Australia Public Private Appointments

A hernia occurs as a lump or bulge when an organ or tissue protrudes through a weakened area in the abdominal wall. They can occur in the groin (femoral or inguinal hernias), through the belly button (umbilical hernia), or through scars from previous abdominal surgery (incisional hernia).
Surgery to fix a hernia may be performed via an open or keyhole (laparoscopic) approach, with or without a mesh.
