The aim of the present study was to propose a new pCLE classification of gastric pit patterns and vessel architecture, and to assess the accuracy and interobserver agreement of this new pCLE classification system in the stomach.
Probe-based confocal laser endomicroscopy (pCLE; Cellvizio, Mauna Kea Technologies, Paris, France) is a newly developed endoscopic device which allows the application of laser microscopy with any conventional endoscope and mosaic imaging. Previous studies have demonstrated its application in various GI diseases, including Barrett's esophagus, colonic adenoma, ulcerative colitis, and etc. However, limited data are provided on exploring the application of pCLE in the stomach. Therefore, the aim of the present study was to propose a new pCLE classification of gastric pit patterns and vessel architecture, and to assess the accuracy and interobserver agreement of this new pCLE classification system in the stomach.
