Neoplasia detection rate, the proportion of Barrett's oesophagus patients with high-grade dysplasia or oesophageal adenocarcinoma detected at index surveillance endoscopy has been proposed as a quality metric. However, the correlation between neoplasia detection rate and a clinically relevant outcome like post-endoscopy Barrett's neoplasia remains unknown. Post-endoscopy Barrett's neoplasia refers to the rate of high-grade dysplasia or oesophageal adenocarcinoma on repeat endoscopy within one year of an index screening examination revealing non-dysplastic Barrett's oesophagus or low-grade dysplasia.

系统评价和荟萃分析：巴雷特食管中的肿瘤检出率和内镜检查后巴雷特瘤形成

肿瘤检出率、重度异型增生或食管腺癌的巴雷特食管患者在指数监测内镜检查中检测到的比例已被提议作为质量指标。然而，肿瘤检出率与临床相关结果（如内窥镜检查后巴雷特瘤形成）之间的相关性仍然未知。内窥镜检查后巴雷特瘤形成是指在一年内重复内镜检查显示非发育不良的巴雷特食管或低度不典型增生的高级别不典型增生或食管腺癌的发生率。
