摘要

超音波診斷膽囊結石至目前已逐漸取代傳統的膽囊攝影方法，尤其是實時間超音波檢查(Real time ultrasonography)的發展，使得膽囊結石的診斷更為容易，且更精確。三軍總醫院自1982年12月至1983年11月一年間由實時間超音波掃描診斷為膽囊結石者共404例，同期間因膽囊結石接受外科手術者77例，其中73例證實有膽囊結石，超音波診斷準確率高達95%，假陽性者4例，假陰性者1例，其靈敏度為98%，若與國外統計結果相比亦大致雷同。超音波檢查除了具有較高的準確率和無放射性顧慮外，更是一費時較短，費用低廉的檢查工具，所以目前已成為篩檢膽道系統病變的一項常規檢查。

The application of ultrasound in gall bladder diseases has replaced the conventional radiological diagnosis in the recent years. The advancement of real time instrumentations makes it easier and more accurate than before. Four hundred and four cases of gall stone were found with real time ultrasonography in the period of Dec. 1982 to Nov. 1983. From the surgical records, seventy seven cases were operated in this period and 73 cases were proved to have gall stone. The accuracy of the real time ultrasonography is 95%. Four cases were false positive and one case was false negative. The sensitivity was 98%. When compared with the literatures, there was no much difference. The noninvasiveness, high accuracy and easy performance make the ultrasonography become a routine test for screening of biliary tract diseases.
