摘要
背景:内镜检查在发现胃早期肿瘤性病变中居重要地位,但不同内镜技术的诊断准确性存在差异。目的:比较常规白光内镜与放大内镜联合窄带成像技术(ME-NBI)对胃早期肿瘤性病变的诊断价值。方法:连续性收集2016年1月—2018年6月在上海仁济医院经白光内镜检查怀疑胃早期肿瘤性病变并取得活检病理结果的患者,择期行ME-NBI并记录白光内镜和ME-NBI诊断;对首次活检病理为非肿瘤性病变者行第二次靶向活检。病理确诊肿瘤性病变者行内镜或外科手术治疗并纳入研究。以术后病理结果为金标准,评估白光内镜和ME-NBI鉴别肠型胃腺瘤与早期胃癌的诊断效能。结果:共纳入301例患者(301处病灶),其中肠型胃腺瘤171例,早期胃癌130例。两名内镜诊断医师的观察者间一致性良好(白光内镜:κ=0.70;ME-NBI:κ=0.81)。ME-NBI鉴别肠型胃腺瘤与早期胃癌的敏感性(89.2%对76.9%)、特异性(90.6%对71.9%)、阳性预测值(87.9%对67.6%)、阴性预测值(91.7%对80.4%)和准确性(90.0%对74.1%)均显著高于白光内镜( P <0.05)。结论:与白光内镜相比,ME-NBI能更好地鉴别肠型胃腺瘤与早期胃癌。
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.
