摘　　要：目的探讨胃镜下采用透明帽对提高Barrett食管（BE）检出率的可行性。方法前瞻性收集168例胃镜检查疑诊为BE的患者，非选择性地分成两组：一组胃镜头端安装一个改良透明帽简称透明帽组，对疑似BE病变处进行活检，共60例；另一组为对照组108例，胃镜下直接对可疑病变进行活检，每例病变活检二块，检出柱状上皮即可诊断为BE。然后再比较两组的检出率。结果透明帽组BE检出率83．3％（50／60），对照组BE检出率69．4％（75／108），两组差异有统计学意义（P〈0．05）。结论胃镜下采用透明帽可使贲门部病变暴露清楚，易于定位活检，有助BE的检出，具有独特的优点和临床应用价值。Objective To evaluate the feasibility of transparent cap-fitted endoscopy in improving diagnostic yield of Barrett＇s esophagus （BE）. Methods A total of 168 patients with endoscopically suspected BE were randomly divided into cap group （n =60） and control group （n = 108 ）. A transparent cap-fitted endoscopy was applied in cap group to take biopsy, while a routine one was used in control group, and 2 biopsies from suspected lesions were collected in each patient. BE was diagnosed in the presence of columnar epithelium and the diagnostic rate was compared between 2 groups. Results The diagnostic rates of BE were 83. 3% （50/60） and 69. 4% （75/108） in cap and control group, respectively （P 〈 0. 05）. Conclusion The lesions at cardia can be exposed clearly with capped endoscopy, which facilitates localized biopsy and BE diagnosis.
