Viewing Time: 41 minutes

This activity consists of the ASGE video, Optical Diagnosis of Colorectal Polyps, followed by an evaluation.

The current pathologic diagnosis of colorectal polyps is at the tissue level. It is based on objective criteria, and is reproducible by various pathologists. The new concept of optical diagnosis is based on these same principles. It is an in-vivo endoscopic diagnosis of the colorectal polyp at the tissue level. The endoscopic image provides the information for the differentiation of colorectal polyp histology that is based on objective validated endoscopic criteria; and that meets society-defined standards of diagnostic performance. The following educational video is on the optical diagnosis of colorectal polyps. We will:

1. Provide the concepts of real-time optical diagnosis of colorectal polyps 
2. Highlight the aim and rationale of the strategy 
3. Dissect the pillars of the optical diagnosis strategy, including a validated classification, society guidelines, prospective clinical studies and infrastructure, such as data storage for photo documentation
4. Outline the steps necessary to practice the technique

Target Audience

Practicing gastrointestinal endoscopists, gastroenterologists, gastroenterology fellows and trainees, medical residents, physician assistants and nurses.

Learning Objectives

Upon completion of this educational activity, participants will be able to:

• Recognize the concepts of real time optical diagnosis during colonoscopy. 

• Discuss the current limitations of the real time optical diagnosis and future works.

• Outline the steps to practice optical diagnosis.
