Join us in the dialogue for better and safer endoscopy. Be a part of the World Endoscopy Organization CORE group.

In a constant effort to reach out to physicians around the world and strive to promote quality in endoscopy, WEO has established a new level of recognition of centers performing endoscopy: Collaboration of Organized and Recognized Endoscopy units (CORE). Through this recognition, WEO wishes to establish a dialogue with endoscopy units around the globe  to improve the practice of endoscopy. WEO will recognize endoscopy units performing upper intestinal endoscopy and/or colonoscopy and that meet endoscopy safety standards of hygiene, disinfection and training that WEO deems necessary for anypractice of endoscopy.


WHO SHOULD APPLY?  Any unit that practices gastrointestinal endoscopy, whether large or small. CORE is open to all sizes of endoscopy units, from multiple room facilities to single physician private offices.


Units need to fill out the online application questionnaire, providing the following:

  • photo of room where endoscopy is to be performed,
  • photo of disinfection area where cleaning takes place

Upon submission, all applications undergo review to ensure the required standards are met, this usually takes one week. If approved, units will receive a confirmation message and will need to open their online account to finalize the application process and download their certificate.


USD 100 – Initial fee for CORE recognition (please note certificates are valid until April 1)

USD 50 – Cost per year for continuation of recognition

Note: Payment of the application fee does not guarantee CORE recognition and is non-refundable. Payment for the annual membership fee is possible via bank transfer, debit and credit card. For those who supply credit card details on application, the fee will be deducted as part of the application process. Those who select to pay via bank transfer will receive the WEO bank details.
