空腹超声诊断贲门及腹段食管肿瘤

目的：本文旨在探讨空腹状态下经腹超声检测腹段食管及贲门部肿瘤的诊断价值。材料和方法：本院病人２２０例，禁食水１０小时以上，经肝窗顺次扫查腹段食管及胃贲门，观察声像图特征及周围淋巴结情况，超声显像与胃镜和手术结果进行盲法对照分析。结果：超声检测腹段食管和贲门结构显示率为９８％，超声诊断的敏感性、特异性和准确度分别为腹段食管癌９１．７％、９８．４％、９８％，贲门癌９５．７％、９７．９％、９７．６％，对

Preliminary study on ultrasonography diagnsing the tumor of cardia and abdominal esophagus at fasting

Objective: To study the diagnostic value of fasting transabdominal ultrasonography for the tumor of cardia and abdominalesophagus.Materials and Methods: 220 patients who fasting for over 10 hours was examined by conventional ultrasonogrphy.the soundbeam through the window of the left lobe of the liver detect the abdominal esophagus and cardia, and observe the echosonogram feature andsurrounding lymph node. the result of ultrasonography was blind compared with endoscopy or surgical operation. Results: the detection rate ofabdominal esophagus and cardia by ultrasonography was 98%. The sensitivity, specificity and accuray were 91. 7%, 98. 4%, 98% respectively for abdominal seophagus carcinoma, and 95. 7%, 97. 9%, 97. 6% respectively for cardia carcinoma, and the accuracy for lymph nodemetastasis wns 81. 3% by ulimsonography. Conclusion: Ultrasonography may become the effective complement of endoscopy and X - ray barium meal for carcinoma of abdominal esophagus and cardia. It has important value in clinical stratgy.
