Dr Marius specialises in a range of gastroenterological conditions including inflammatory bowel, irritable bowel, liver, biliary, pancreatic, gastric and intestinal disorders. He believes in empowering the patient with the knowledge about their condition, fixing the underlying cause if possible and creating a personalised treatment plan. He is experienced in minimally invasive endoscopic procedures including gastroscopy, colonoscopy, endoscopic ultrasound, spyglass and ERCP. With the implementation of new endoscopic techniques to treat pancreatic collection, 3 peoples lives were saved, 2 months of ICU time saved and resulted in large cost savings for WDHB. marius van Rijnsoever

Dr Marius is a great doctor. He goes over and above the expected standard of care when dealing with his patients. He’s smart, kind and patient, especially during stressful times.

Would highly recommend to anyone looking for a great Gastroenterologist.
