“…16 There have been multiple studies looking at the reproducibility of NBI with magnification. [17][18][19][20][21] Curvers et al 17 looked at the interobserver agreement based on the mucosal and vascular morphology described previously by Kara et al 10 NBI did not improve interobserver agreement or accuracy over HD-WLE. The interobserver agreement for NBI diagnosis ranged from a k of 0.40 to 0.56 (moderate) and did not significantly differ between expert and nonexpert endoscopists.…”

“…In order to standardize endoscopic evaluation of BE and dysplastic lesions, various classification systems have been developed, combining magnification endoscopy and NBI . However, these systems have been suboptimal with regard to accuracy, interobserver and intraobserver agreements between non‐experts and experts . Hence, an international working group consisting of experts from the USA, Europe and Japan, known as the Barrett's International NBI Group (BING), convened to develop criteria to use NBI in BE.…”

Barrett's esophagus (BE), a premalignant condition of the lower esophagus, is increasingly prevalent in Asia. However, endoscopic and histopathological criteria vary widely between studies across Asia, making it challenging to assess comparability between geographical regions. Furthermore, guidelines from various societies worldwide provide differing viewpoints and definitions, leading to diagnostic challenges that affect prognostication of the condition. In this review, the authors discuss the controversies surrounding the diagnosis of BE, particularly in Asia. Differences between guidelines worldwide are summarized with further discussion regarding various classifications of BE used, different definitions of gastroesophageal junction used across geographical regions and the clinical implications of intestinal metaplasia in the setting of BE. Although many guidelines recommend the Seattle protocol as the preferred approach regarding dysplasia surveillance in BE, some limitations exist, leading to poor adherence. Newer technologies, such as acetic acid‐enhanced magnification endoscopy, narrow band imaging, Raman spectroscopy, molecular approaches and the use of artificial intelligence appear promising in addressing these problems, but further studies are required before implementation into routine clinical practice. The Asian Barrett's Consortium also outlines its ongoing plans to tackle the challenge of standardizing the diagnosis of BE in Asia.

“…Whether narrow band imaging or related techniques are useful or mandatory remains somewhat controversial although the latter technique is often used in expert units. 12,13 Neoplastic changes may present as a visible focal suspicious alteration of the mucosal lining to be graded according to the Paris classification system (Figs 5,6). Early neoplastic lesions are often centered in the 2-o'clock to 5-o'clock spatial location.…”
