COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
i. To determine whether Confocal Laser Endomicroscopy (CLE) with optical biopsy and targeted
mucosal biopsy improves the diagnostic yield of gastric IM/IN/CA in high risk populations
compared to WLE with standard biopsy protocol.

ii. To determine whether CLE with optical biopsy and targeted biopsy, as compared to WLE with
standard biopsy, can reduce the number of biopsies needed per patient for detection of
gastric IM/IN/carcinoma without the loss of corresponding diagnostic yield.

iii. To compare the sensitivity and specificity of CLE with WLE for the detection of gastric
IM/IN/CA.
