The optical-morphological diagnosis ratio in esophageal metaplasia

Abstract

Objective. To analyze the esophageal metaplasia types in accordance to data of videoesophagogastroduodenoscopy and morphological investigations, to determine the ratio of optical and morphological diagnosis in esophageal metaplasia.
 Materials and methods. Retrospective investigation was conducted, concerning the results of 237 videoesophagogastroduodenoscopy with high resolution capacity in presence of suspicion for BE diagnosis, using gastroscopes Olympus GIF HQ-190, -180, Olympus EVIS EXERA II, Olympus EVIS EXERA III, EVIS X1 in conjunction with digital chromoscopy and epithelial biopsy of the esophageal mucosa affected with further morphological investigation on base of Shalimov National Institute of Surgery and Transplantology during 2014 - 2022 yrs, using modern protocols (biopsies taken from 4 quadrants along the metaplasia esophageal coverage every 2 sm and on the apex of the mostly proximally located fragment) with further histological investigation.
 Results. In accordance to videoesophagogastroduodenoscopy data there was diagnosed BE in 237 patients. Endoscopic picture of metaplasia in regime of digital chromoscopy looks like tongues of flame of reddish color on background of gray esophageal epithelium. In total a complete coincidence of optical and morphological diagnosis was noted in 192 (81.0%) of 237 patients.
 Conclusion. For today practice morphological verification of BE remains an objective criterion. But optical diagnosis, established, using videoesophagogastroduodenoscopy of high resolution capacity and digital chromoscopy, was confirmed in 81.0% of observations. It is possible to prognosticate, that in near future, taking into account technical progress in possibilities of endoscopes, for establishment of the BE diagnosis application of videoesophagogastroduodenoscopy with high resolution capacity and narrow-band chromoscopy would appear sufficient. Further retrospective investigations in this direction, using modernized gastroscopes with high resolution capacity may constitute a good perspective.
