ABSTRACT
Background:
Endoscopy plays an important role in the early detection of gastric neoplastic lesions, but different techniques lead to different diagnostic accuracy.Aims:
To explore and compare the diagnostic value of conventional endoscopy with white light imaging (WLI) and magnifying endoscopy with narrow-band imaging (ME-NBI) for early gastric neoplastic lesions.Methods:
Patients suspected of having early gastric neoplastic lesions by WLI were collected consecutively from Jan. 2016 to Jun. 2018 at Shanghai Renji Hospital, and received ME-NBI within 2 weeks. The diagnosis based on WLI and ME-NBI was recorded, respectively. Targeted biopsy was re-performed in patients with suspected neoplastic lesion yet having no abnormalities in first biopsy. Patients with neoplastic lesions proved by pathology were treated with endoscopic resection or surgical operation and enrolled in the analysis. Using pathological diagnosis as gold standard, the diagnostic performance of WLI and ME-NBI for distinguishing intestinal-type gastric adenoma and early gastric cancer (EGC) was evaluated.Results:
A total of 301 patients (301 lesions) were included, including 171 adenoma and 130 EGC. The interobserver agreement between two endoscopists was optimal for both WLI and ME-NBI observation (WLI κ=0.70; ME-NBI κ=0.81). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ME-NBI for distinguishing intestinal-type gastric adenoma from EGC were higher than those of WLI (89.2% vs. 76.9%, 90.6% vs. 71.9%, 87.9% vs. 67.6%, 91.7% vs. 80.4%, and 90.0% vs. 74.1%, respectively, all P<0.05).Conclusions:
ME-NBI is superior to WLI in distinguishing intestinal-type gastric adenoma from EGC.
