Our Research

The key themes of pioneering research within the Academic Colorectal Unit are:

  • Health Services: state-wide, population-based studies to explore variation in outcomes following major colorectal surgery;
  • Clinical Science: advanced, state-of-the-art physiological measurement of gastrointestinal function to accurately define phenotypic variation in pelvic floor and functional gastrointestinal disorders;
  • Translational Basic Science: enteric neuroscience research to determine the molecular, electrophysiological and neuropathophysiological basis of gastrointestinal conditions.

Each year more than 230 million major operations are performed worldwide, one for every 25 people in the world. Diseases of the bowel are among the commonest in the population, with bowel cancer being the second most common type of newly diagnosed cancer in Australia and the second biggest cancer killer.

Furthermore, bowel problems such as constipation and incontinence are one of the most frequent reasons why people visit doctors, with approximately 1 in 10 people suffering with each of these problems. Despite these staggering statistics, very little is known about how the bowel works in healthy individuals and what goes wrong in diseases and disorders such as cancer and constipation.

More importantly, it is unclear how many operations are performed for bowel problems in Australia each year and what results are achieved following surgery.

Key Achievements

The research Group focuses on clinical, epidemiological and translational research into diseases and disorders of the gastrointestinal tract. There are established International collaborations with: Department of Cell and Molecular Biology, Medical Nobel Institute, Karolinska Institute, Sweden Center for Health Outcomes & Policy, University of Michigan, USA.

Recently, we have been able to successfully perform electrophysiological recordings from the nerves supplying the bowel in humans, which has enabled us to 'listen in' to the messages passing along nerves to the muscles that control the bowel. We have also mapped different classes of neurons and perform neurochemical coding to better identify different groups among the many hundreds of thousands of nerves that are contained within the bowel using special techniques.
