Abstract
AbstractObjectivesThe utility of texture and color enhancement imaging (TXI) in detecting gastric cancer (GC) has been investigated. However, few reports exist on TXI mode2 (TXI2) used for detecting GC; this study investigated the efficacy of TXI2 in GC detection during screening endoscopy.MethodsThis study enrolled 13,440 participants with confirmed Helicobacter pylori (H. pylori) infection status who underwent screening endoscopy by 20 endoscopists in our health screening center. The participants were divided into two groups: one group was observed using white light imaging (WLI) only by 17 endoscopists (WLI group, 10,745 participants), and the other group was observed using TXI2 only by the other three endoscopists (TXI2 group, 2695 participants). We analyzed the detection rate and the characteristics of GC. In addition, considering the bias due to the diagnostic ability, we analyzed the subset of the WLI group where the participants were evaluated by the top three endoscopists based on their GC detection rate (Expert‐WLI group, 2792 participants) for comparison with the TXI2 group.ResultsFifty patients were diagnosed with GC. The GC detection rates were 0.68% and 0.71% in the Expert‐WLI and TXI2 groups, respectively. In patients who underwent screening endoscopy after H. pylori eradication, the detection rates of differentiated GC, L‐region lesions, and surface depressed‐type lesions were 0.52%, 0%, and 0.43% in the Expert‐WLI group and 1.36%, 0.78%, and 1.36% in the TXI2 group, respectively.ConclusionsIn screening endoscopy, the detectability of differentiated GC and L‐region lesions and surface depressed‐type lesions after H. pylori eradication was higher in TXI2.
