“…Related to this problem, a recent study has reported outcomes of training in NBI magnification. This study revealed that an hour-long training lecture could increase the differential diagnostic skills of inexperienced NBImagnification operators to expert levels [24]. Properly conducted short training in FICE magnification performed at our institution potentially offers the same effectiveness as that reported for NBI.…”

“…In addition, it requires considerable experience to use ME-NBI for diagnosis of gastric cancer. Studies have shown that advanced training can improve the diagnostic rate of early gastric cancer [31,32]. Therefore, the differences in the experience level of the endoscopists among the studies included may also be a factor contributing to heterogeneity.…”

Objective Magnifying endoscopy with narrow band imaging (ME-NBI) is widely used in gastroscopy, especially in the diagnosis of early gastric cancer. The purpose of this meta-analysis is to compare the diagnostic efficacy of white light imaging (WLI) and that of ME-NBI for early gastric cancer. Methods PubMed/MEDLINE, EMBASE, and the Cochrane Library were searched to identify studies which met the inclusion criteria. A random-effects model was used to calculate overall sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC) to assess the diagnostic efficacy of WLI and ME-NBI in early gastric cancer. Sensitivity analysis was performed to assess the stability of the results. Results Ten studies met the inclusion criteria, and included 1724 patients and 2153 lesions. The pooled sensitivity, specificity, and AUC for the diagnosis of early gastric cancer using WLI were 0.48 [95 % confidence interval (CI) 0.39-0.57; I 2 = 78.6 %], 0.67 (95 % CI 0.62-0.71; I 2 = 81.9 %), and 0.62, respectively. The pooled sensitivity, specificity, and AUC using ME-NBI were 0.83 (95 % CI 0.79-0.87; I 2 = 79.8 %), 0.96 (95 % CI 0.95-0.97; I 2 = 89.3 %), and 0.96, respectively. The studies showed a high degree of heterogeneity. Further sensitivity analysis was mainly performed for the studies of small lesions (mean size 10 mm or less) and the studies with a the score of 12 points or greater in the literature quality assessment, and the AUCs for ME-NBI for diagnosis of early gastric cancer were between 0.93 and 0.98, which suggested that the diagnostic value was still high and stable. Conclusion Compared with WLI, ME-NBI can effectively diagnose early gastric cancer.

Diagnostic accuracy of narrow-band imaging and pit pattern analysis significantly improved for less-experienced endoscopists after an expanded training program

Abstract: Using high-magnification NBI increased the differential diagnostic skill of the LEE group after expanded training so that it was equivalent to that of the HEE group.
