 In clinical practice, two types of ultra-magnifying endoscopes are currently being applied for in vivo cellular observation:endocytoscopy(Endocyto ; CF-H290ECI, Olympus Corp, Tokyo)and confocal laser endomicroscopy(CLE ; Cellvizio, Mauna Kea Corp., Paris). The Endocyto technique uses an endoscope with a microscopic lens attached to its tip. It allows the visualization of cellular lumens, nuclei, and vessels with a 520× magnification. On the other hand, CLE consists of probe-based laser endoscope, which analyzes the excitatory light emitted through fluoresce in the mucosa. It allows the visualization of cellular lumens and vessels with a 1000× magnification. The present review is manly focused on Endocyto, which was launched in February, 2018. We present its strengths, methodologies, and diagnostic performance. Endocyto carries additional diagnostic value to the current diagnosis based on pit pattern classification, In additon it can contribute to enhancing diagnostic confidence levels.
