Within Gastroenterology, we conduct research in the key areas of viral hepatitis (Hepatitis B and C), inflammatory bowel disease (Crohn’s disease and Ulcerative Colitis), chronic liver disease and Clostridium difficile associated diarrhea. We are involved in investigator initiated and industry sponsored clinical trials. Participating in these clinical trials enables our service to provide better patient treatment options and improved patient outcomes for both liver and luminal gastroenterology disease. We are also currently participating in a national audit of inflammatory bowel disease quality of care in collaboration with Crohn’s and Colitis Australia. We plan to continue to be involved in a range of studies so the unit can continue to improve staff education and teaching, broaden patient treatment options, and improve the outcomes for our patients.
Within Endoscopic Services, our investigator-initiated research has focused on ways to improve our endoscopic clinical outcomes, as well as on quality assurance and audit measures. We are involved in multiple multicenter studies together with other leading endoscopy units in Australasia. The main focus of our research is studying novel endoscopic techniques and monitoring existing and emerging endoscopic techniques that are minimally invasive ways to treat gastrointestinal neoplasia and other pathology, and thereby minimise the need for more invasive surgical interventions that may have greater associated morbidity and mortality. As a result of the outcomes of our studies, we have educated our referring endoscopists about lesion identification, classification and suitability for EMR (endoscopic mucosal resection), avoidance of interventions that impair outcomes, and refined our pathway to EMR via our endoscopy clinic. We also learnt that we have more work to do in the realm of detection of a relatively newly described entity of flat polyps known as sessile serrated adenomas (SSA) and we will focus on educating our endoscopists to enhance detection of these lesions that are likely responsible for some interval colorectal cancers, and then further study our detection rates and outcomes. We will also aim to further study our success in achieving other quality indicators such as high adenoma detection rates, ERCP efficacy and safety and study the implementation of our new nurse endoscopy program.
