食管钡餐连续摄影用于诊断早期食管癌的初步临床应用

目的 :介绍食管钡餐连续摄影用于诊断早期食管癌的初步临床应用。方法 :用德国产的数字化胃肠机检查并诊断了 6例早期食管癌病人。与常规食管双重对比造影类似 ,病人立位口服钡剂 ,同时进行连续摄影 ,速度为 2帧 s,持续约 10s。观察不同的时相 ,包括充盈相、黏膜相和双对比相。结果 :在 6例病人中可见食管功能的改变及黏膜皱襞的病变 ,用连续摄影诊断后经内镜及病理检查确诊。 4例病人有轻度扩张受限 ,2例病人有痉挛性收缩 ,1例有钡剂滞留。 6例病人中均可见增粗的或中断的黏膜。 5例病人可见小溃疡。结论 :食管钡餐连续摄影可提供更全面的信息。用此法更可提供食管功能性的改变。

Clinical Applications of Successive Spot Radiographs in Esophagography for Diagnosing the Early Esophageal Cancer

Objective:To introduce primary experience of clinical applications of successive spot radiographs in esophagography for the diagnosis of early esophageal cancer(EEC). Methods: Six patients with EEC were examined and diagnosed by a digital X-ray machine.According to the routine double contrast study of esophagus,the patient gulped a barium suspension in the upright position when the successive films were taken by 2 frames per second lasting for about 10 seconds.Various phases were obtained including barium-filled views,mucosal relief views and double contrast views. Results: Functional changes and abnormal mucosal folds of esophagus were present on successive spot radiographs of esophagography in patients with EEC and those patients with EEC were confirmed by endoscopic and pathologic findings.Four patients had mild loss of distensibility,2 patients had spasmodic contraction and 1 patient had barium retention.Thickened or interrupted folds were found in all cases.Little niches were detected in 5 of 6 patients. Conclusion: Evidence presented in barium studies of esophagus is more comprehensive and intact for the diagnosis of EEC when successive spot radiographs are employed.Functional changes of esophagus are more evident with this approach.
