[Novel endoscopic terminology: NBI visualization]

Area of Science:

• Gastroenterology
• Endoscopic Imaging
• Pathomorphology

Background:

• Chronic diseases of the stomach and duodenum require accurate diagnostic methods.
• Narrow Band Imaging (NBI) offers enhanced visualization of mucosal details.
• Standard endoscopic assessment may have limitations in identifying subtle mucosal changes.

Purpose of the Study:

• To develop novel criteria for evaluating gastric and duodenal mucosa images.
• To enhance diagnostic accuracy using NBI endoscopic system.
• To establish a standardized protocol for NBI-based endoscopic assessment.

Main Methods:

• Comparison of endoscopic and morphological findings in 460 patients.
• Standard esophagogastroduodenoscopy using an Olympus EVIS EXERA-II GIF H180 with NBI.
• Pathomorphological analysis of biopsy material.

Main Results:

• A new system for visual picture evaluation in monochromatic light was developed.
• The NBI system demonstrated higher significance in identifying inflammatory and destructive mucosal processes.
• Improved detection of structural alterations, their location, and extent was achieved.

Conclusions:

• A protocol for describing endoscopic findings with NBI visualization in monochromatic light is proposed.
• This protocol assists physicians in accurately estimating images and interpreting mucosal changes.
• The developed criteria enhance the diagnostic utility of NBI in gastroenterology.
