目的：使用高分辨率NBI镜镜的分级内窥镜系统已被证明可以准确识别需要监测的广发性GIM （EGGIM）患者。然而，没有描述可用的替代系统，如富士胶片的新系统，BLI。我们的目的是确定BLI在GIM诊断和分期方面的可靠性和准确性。方法：连续的一系列患者（n= 29），先前通过NBI评估，胃的全谱变化（OLGIM 0-IV）提交使用富士meg - 760zhd /ELUXEO-VP7000胃镜检查，内窥镜医师（对先前的组织学状态不知情）使用BLI-bright模式实时确定EGGIM评分（例如，胃窦和体的小弯曲0-2，胃窦和体和切牙的大弯曲，总计0-10）。采用Pimentel-Nunes P等人先前的分类，对3名观察者使用WLE、LCI和BLI来确定BLI的可靠性（每个站点图像n= 32）。其次，通过将先前的EGGIM（截止值为4）与NBI和当前的OLGIM状态进行比较来确定准确性。结果：基于BLI内镜图像的组织学推定的整体观察者间信度（wK 0.80 [95% CI: 0.64-0.93]）和LCI （wK 0.76 [95% CI: 0.53-0.90]）明显优于WLE （wK 0.43 [95% CI: 0.20-0.66]）。WLE的确定性比例为50%至62%，LCI为59%至81%，BLI为78%至91%。准确性报告见表1。
Aims:A grading endoscopic system using high-resolution scopes with NBI has been shown to accurately identify patients with extensive GIM (EGGIM) that need surveillance. However, no description is available with alternative systems such as the new system of Fujifilm, BLI. We aim to determine the reliability and accuracy of BLI regarding the diagnosis and staging of GIM.Methods:A consecutive series of patients (n= 29), previously assessed by NBI, with a full spectrum of gastric changes (OLGIM 0-IV) were submitted to gastroscopies using FujifilmEG-760ZHD/ELUXEO-VP7000 and endoscopists (blinded to the previous histologic status) were asked to determine EGGIM score on real-time using BLI-bright mode (eg, 0–2 for the lesser curvature of antrum and corpus, greater curvature of antrum and corpus and incisura, total 0–10). Reliability with BLI using the previous classification by Pimentel-Nunes P et al. among 3 observers was determined with WLE, LCI and BLI (n= 32 per site images). Secondly, accuracy was determined by comparing with previously EGGIM (cutoff of 4) with NBI and current OLGIM status.Results:The overall interobserver reliability for histologic presumption based on endoscopic images with BLI (wK 0.80 [95% CI: 0.64–0.93]) and LCI (wK 0.76 [95% CI: 0.53–0.90]) was substantially better than WLE (wK 0.43 [95% CI: 0.20–0.66]. The proportion of certainty varied between 50 to 62% for WLE, 59 to 81% for LCI, 78 to 91% for BLI. Accuracy is reported in table 1.
