Current guidelines recommend that endoscopic surveillance of Barrett's esophagus (BE) be performed by using a strict biopsy protocol. However, novel methods to improve BE surveillance are still needed.
To evaluate the impact of Barrett's inspection time (BIT) on yield of surveillance.
Post hoc analysis of data obtained from a clinical trial.
Five tertiary referral centers.
Patients undergoing BE surveillance.
Coordinators prospectively recorded the time spent inspecting the BE mucosa with a stopwatch.
Endoscopically suspicious lesions, high-grade dysplasia (HGD)/esophageal adenocarcinoma (EAC).
A total of 112 patients underwent endoscopic surveillance by 11 individual endoscopists. Patients with longer BITs were more likely to have an endoscopically suspicious lesion (P < .001) and more endoscopically suspicious lesions (P = .0001) and receive a diagnosis of HGD/EAC (P = .001). There was a direct correlation between the endoscopist's mean BIT per centimeter of BE and the detection of patients with HGD/EAC (ρ = .63, P = .03). Endoscopists who had an average BIT longer than 1 minute per centimeter of BE detected more patients with endoscopically suspicious lesions (54.2% vs 13.3%, P = .04), and there was a trend toward a higher detection rate of HGD/EAC (40.2% vs 6.7%, P = .06).
Post hoc analysis of an enriched study population and experienced endoscopists at tertiary referral centers.
Longer time spent inspecting the BE segment is associated with the increased detection of HGD/EAC. Taking additional time to perform a thorough examination of the BE mucosa may serve as an easy and widely available method to improve the yield of BE surveillance.
目前的指南建议使用严格的活检方案对 Barrett 食管(BE)进行内镜监测。然而,仍需要新的方法来提高 BE 的监测效果。
评估 Barrett 食管检查时间(BIT)对监测结果的影响。
对临床试验中获得的数据进行的事后分析。
五个三级转诊中心。
接受 BE 监测的患者。
协调员使用秒表前瞻性地记录检查 BE 黏膜的时间。
内镜下可疑病变、高级别异型增生(HGD)/食管腺癌(EAC)。
共有 112 例患者由 11 名个体内镜医生进行内镜监测。BIT 较长的患者更有可能出现内镜下可疑病变(P<0.001)和更多的内镜下可疑病变(P=0.0001),并被诊断为 HGD/EAC(P=0.001)。内镜医生检查 BE 每厘米的平均 BIT 与 HGD/EAC 患者的检出率呈直接相关(ρ=0.63,P=0.03)。平均 BIT 超过 1 分钟/厘米 BE 的内镜医生检测到更多内镜下可疑病变患者(54.2%比 13.3%,P=0.04),并且有更高的 HGD/EAC 检出率趋势(40.2%比 6.7%,P=0.06)。
在三级转诊中心对富集研究人群和经验丰富的内镜医生进行的事后分析。
花费更多时间检查 BE 段与 HGD/EAC 的检出率增加有关。花额外的时间对 BE 黏膜进行彻底检查可能是提高 BE 监测效果的一种简单且广泛可用的方法。
