摘　　要：目的:探讨胃镜与99Tcm-EHIDA的核素显像对胆汁反流性胃炎的诊断价值。方法:分析比较胃镜与改良的核素显像对胆汁反流性胃炎诊断的敏感性、特异性和准确性,并与病理检查结果进行了对照比较。结果:核素显像诊断的敏感性、特异性和准确性分别为:73.9%,94.1%和82.5%;胃镜诊断的敏感性、特异性和准确性分别为:78.3%,29.4%和60.0%。核素显像诊断的特异性和准确性高于胃镜检查,敏感性相近。结论:胃镜能直接观察到胆汁反流的存在,但其对消化道的刺激可能使假阳性率增高。核素显像具有较高的准确性和特异性,胃镜与核素显像结合病理检查,三者可以提高诊断的准确性和敏感性。Objective： To evaluate diagnostic value of gastrofiberscope and the improved ^99Fc^m-EHIDA gastrointestinal γ- flare imaging method to bile reflux gastritis. Methods： The diagnostic sensitivity, specificity and accuracy of gastrofiberscope and improved radionuclide imaging to bile reflux grastritis were analyzed and compared with the histological results. Results： The diagnostic sensitivity ,specificity and accuracy of radionuclide imaging to bile reflux grasritis were 73.9% ,94.1% and 82.5% respectively;correspondingly,the diagnostic sensitivity ,specificity and accuracy of gastrofiberscope were 78.3% ,29.4% and 60.0%. The diagnostic specificity and accuracy of improved radionuclide imaging in bile reflux grasritis were higher than those of gastrofiberscope. The diagnostic sensitivity of radionuclide imaging was similar to that of gastrofiberscope. Conclusion： The gastrofiberscopy is a straightway to observe the reflux of the bile .The false positive rate may be increased result of the stimulation. The improved radionuclide imaging has a higher accuracy and specificity. The diagnostic accuracy and sensitivity are promoted if radionuclide imaging and gastrofiberscope are combined with histological check.
