About
At Gastroenterology Services Tasmania, we strive to provide quality, accessible and affordable care and services for our patients.
We focus on the patient as a whole person, treating gut problems using traditional therapies as well as collaborating with allied health specialists for the physical and psychological aspects.
Our direct access endoscopy service allows suitable patients to be referred by their GP directly for gastroscopy and/or colonoscopy without having to undergo a consultation in rooms prior, thus fast-tracking the investigative procedure.

Dr Mark Veldhuis has grown up and lived in Launceston for most of his life.
Mark studied Medicine at the University of Queensland graduating in 2002 after initially studying Medical Laboratory Science at the University of Tasmania and working as a Laboratory Scientist in Launceston (Launceston General Hospital) and London (Chase Farm Hospital, Enfield).
He is a general gastroenterologist who enjoys the breadth of practice offered by working in his home city of Launceston and has a specific interest in inflammatory bowel diseases (Crohn’s disease and Ulcerative Colitis) but consults broadly in all aspects of gastroenterology including hepatology (liver), nutritional and functional pathologies and endoscopy.
He has a very practical and holistic approach to treating patients with all aspects of gut disorders. Mark has extensive endoscopic experience including polyp resection, haemorrhoid/variceal banding and many interventional techniques employed in the practice of quality endoscopy. He is proud to have recently partnered in new device technology allowing Parkinson’s Disease sufferers access to treatment options never before available in Tasmania.
His interests outside of work include a love of travel. He enjoys his family time especially skiing and time on the East Coast of Tasmania. He enjoys golf and beekeeping as well as time spent with his guitar or in his shed building furniture.

Services
Referrals
Direct access endoscopy is defined as the direct referral of a patient for gastroscopy or colonoscopy without a formal consultation in advance.
Despite offering patients rapid access, direct access endoscopy is not suitable for all patients, particularly those with significant co-morbidities which might impact on pre-procedure advice, pre-procedure medication management, or even the most appropriate setting (day procedure centre or larger hospital) for the procedure.
Patients NOT eligible for this category include:
- Patients with significant cardiac disease (e.g. severe aortic
stenosis, mechanical valve replacement, pulmonary
hypertension, decompensated cardiac failure, or poorly
controlled ischaemic heart disease) - Significant airway’s disease
- Severe obstructive sleep apnoea
- Poorly controlled insulin dependent diabetes.
Special consideration may need to be given to:
- Morbidly obese patients (BMI>40kg/m2)
- Patients on warfarin or other anti-coagulants and blood
thinners - Any elderly patient with significant frailty, particularly nursing
home patients or patients with significant mobility issues - A patient’s social circumstances, for example an elderly patient living alone may not be suitable to take colonoscopy bowel preparation without adequate supervision due to the risk of falls.
