Participation in the drafting of three European guidelines on endoscopic optical diagnosis

Dr Ignasi Puig, coordinator of the GOES research group, has recently taken part in the development of three clinical guidelines from the European Society of Gastrointestinal Endoscopy (ESGE). The papers provide recommendations for the use of endoscopic optical diagnosis, which aims to predict the histology of gastrointestinal lesions by observing their surface with light filters, stains, and increased image resolution.

The first clinical guideline summarizes the scientific evidence and provides recommendations for system indications and classifications for optical diagnosis in colorectal lesions. The guideline can be consulted here.

As the positive results obtained at certain referral centres around the world will only be reproduced in others once clinicians have already obtained a certain expertise, the second clinical guideline sets out ways to help regulate and validate the learning required.

The third and final published guide establishes a precision threshold for endoscopic optical diagnosis to replace histological diagnosis. This threshold has been established based on the simulation of possible clinical consequences in 1,000 patients with a diminutive polyp. Click here to consult the guide.

Surface staining and increased resolution of this lesion can diagnose early colorectal cancer and help selected the most appropriate treatment.

Taking part in the development of these guides has allowed us to work with leading figures in the field of high-quality optical diagnostics, such as Evelien Dekker (Netherlands) and Raff Bisschops (Belgium), and other renowned researchers from the United Kingdom, Italy, Poland, Norway, Germany, and France.
