Endocytoscopy aids in the virtual realization of histology. Herein, we aimed to investigate gastric lesions using single-stain endocytoscopy and compare them using magnifying endoscopy with narrow-band imaging (ME-NBI) in terms of diagnostic yield in vivo.\u003Cbr>Methods and methods In the present prospective study we registered 24 patients with gastric neoplasms and |\n| --- |\n| ,\u003Cbr>retrospectively reviewed their images. Three endoscopists reviewed the images of gastric neoplasms using white light, ME-NBI, and endocytoscopy. The diagnostic yield of endocytoscopy in early gastric cancer (EGC) was assessed using histopathology as the gold standard.\u003Cbr>Results Endocytoscopy was performed in 24 patients with gastric neoplasms. Of these, 15 patients had adenocarcinomas, while nine patients had low-grade dysplasia. The sensitivity, specificity, and accuracy of endocytoscopy for EGC detection were reported as 80.0%[95% confidence interval (CI), 51.9–95.7], 66.7%(95% CI, 58.4–91.9), and 75.0%(95% CI, 53.3–90.2) by endoscopist A; 80.0%(95% CI, 51.9–95.7), 44.4%(95% CI, 13.7–78.8), and 66.7%(95% CI, 44.7–84.4) by endoscopist B; and 93.3%(95% CI, 68.1–99.8), 55.6%(95% CI, 21.2–86.3), and 79.2%(95% CI, 57.9–92.8) by endoscopist C; these findings were not inferior to NBI. The inter-observer agreement, κ statistic = 0.67 (95% CI, 0.43–0.90) was favorable. Conclusion Endocytoscopy aid in the diagnosis of EGC because of its better sensitivity and accuracy compared to NBI or white-light imaging. However, further large-scale studies are required to confirm our findings. Eur J Gastroenterol Hepatol 35 :\u003Cbr>530–536\u003Cbr> Copyright © 2023 The Author(s) .
