Rapid & Direct Endoscopy (Open Access)

Rapid and Direct Endoscopy enables patients (who meet select admission criteria) to book their endoscopies directly and bypass the initial specialist consultation if deemed unnecessary. Dr Tan is an avid supporter of Rapid and Direct Endoscopy, as it facilitates early diagnosis and triages patients who have positive test results from Australia’s National Bowel Cancer Screening Program. The program gives patients a more efficient pathway to investigate digestive issues and reduce wait times.
