PURPOSE OF REVIEW: Barrett's esophagus is the premalignant condition for esophageal cancer and the diagnosis of esophageal adenocarcinoma on index endoscopy is increasing. Many advanced endoscopic techniques are available and aim to identify Barrett's esophagus-associated neoplasia earlier, thereby preventing progression into malignancy. RECENT FINDINGS: It is well established adherence to Seattle protocol increases dysplasia detection but leaves large portions of mucosa unsampled. Recent attention has been given to wide-area transepithelial sampling as an additional means of biopsy and shows increased dysplasia detection rates. Many endoscopic techniques aim to increase the success of diagnosis of Barrett's esophagus-associated neoplasia, including probe confocal endomicroscopy, volumetric laser endomicroscopy, and virtual chromoendoscopy. Interestingly, volumetric laser endomicroscopy may also be useful in delineating margins during endoscopic mucosal resection, leading to both diagnostic and therapeutic applications. SUMMARY: Advanced endoscopic techniques are available to increase detection of Barrett's esophagus-associated neoplasia; however, these remain localized to academic centers of excellence. With recent advancements in both sampling techniques and the potential application of imaging to therapeutics, these techniques are becoming more accessible to community endoscopists.
目的综述:巴雷特食管是食管癌的癌前病变,索引内镜诊断食管腺癌的比例正在增加。有许多先进的内镜技术可用于更早地识别巴雷特食管相关肿瘤,从而防止进展为恶性肿瘤。
最近的发现:人们已经充分认识到,遵循西雅图协议可以提高异型增生的检出率,但仍有很大一部分黏膜未被取样。最近,人们关注的焦点是广泛的跨上皮采样作为额外的活检手段,并显示出更高的异型增生检出率。许多内镜技术旨在提高巴雷特食管相关肿瘤的诊断成功率,包括探针共聚焦内镜、体激光共聚焦内镜和虚拟染色内镜。有趣的是,体激光共聚焦内镜在界定内镜黏膜下切除的边缘时也可能有用,从而具有诊断和治疗应用。
总结:现已有先进的内镜技术可用于提高巴雷特食管相关肿瘤的检出率;然而,这些技术仍局限于优秀的学术中心。随着采样技术的最新进展以及成像在治疗中的潜在应用,这些技术对社区内镜医生来说越来越容易获得。
