Areas of specialisation

Weight Loss Surgery

Weight loss surgery uses a set of techniques and surgical procedures that help fight obesity and improve a patient’s health.

Hernia Repair

A hernia appears as a lump, most commonly in the abdominal or groin area. They occur when an organ, often the bowel, protrudes through the cavity which normally contains it.

Gallbladder Surgery

Gallbladder surgery is a surgical procedure that is performed to remove the gallbladder, an organ located in the lower part of the liver that serves as a reserve for bile.

Acid Reflux

Gastroesophageal reflux disease (GERD) is a digestive disorder where acid from the stomach leaks back into the oesophagus and causes irritation and discomfort..


Laparoscopy is a minimally invasive surgical technique which allows the surgeon to operate without the need for deep or large incisions in the skin. This technique is also known as keyhole surgery.


Gastroscopy is a clinical diagnostic test. Using a thin tube (an endoscope), the inside of the oesophagus, the stomach and the first part of the small intestine (the duodenum) can be visualised.
