 Dr Stuart Kostalas - "Aiming to provide excellent endoscopic services"

Dr Kostalas is a medical specialist in both Gastroenterology (the whole gastrointestinal tract and digestive system), Hepatology (the study of the liver) and interventional endoscopy. He provides a comprehensive service to his patients, exploring all aspects of their medical conditions in order to tailor optimal treatment. 

Dr Kostalas is a highly trained, experienced and skilled interventional endoscopist in the Port Macquarie area. He performs high volume, advanced interventional endoscopic procedures in Port Macquarie. He has conjoint committee accreditation in Gastroscopy, Colonoscopy and ERCP. His passion is providing very high quality colonoscopy, particularly the detection of polyps and their endoscopic removal (see QIC for more information). He also has further training in advanced therapeutic endoscopy involving complex neoplastic tissue resection (early cancer removal). In 2016 Dr Kostalas was recertified by GESA in colonoscopy.

Large colonic polyps and early cancers which previously required operations can often be removed endoscopically. Lesions suitable for this can be assessed by Dr Kostalas who performs Endoscopic Submucosal Dissection (ESD), a technique which has previously only routinely been offered in Asia.

Patients consulting Dr Kostalas have access to modern and advanced diagnostic and therapeutic modalities, including endoscopic and other procedures, along with state-of-the-art knowledge and technologies. Dr Kostalas has a close working relationship with other specialists and referring doctors, in order to integrate and optimise patient management.
