内镜超声检查对胆总管扩张的诊断价值

目的 探讨内镜超超检查（ｅｎｄｏｓｃｏｐｉｃ ｕｌｔｒａｓｏｎｏｇｒａｐｈｙ，ＥＵＳ）对不明原因的胆总管扩张的诊断和鉴别诊断价值。方法 对４３例经多次腹部Ｂ超检查未能明确病因诊断的胆总管扩张患者行ＥＵＳ，并与手术和病理结果进行比较。结果 ＥＵＳ诊断为胆总管结石３４例，胰头占位性病变５例，胆道系统肿瘤２例，先天性胆道扩张１例。ＥＵＳ检查阳性率９７．７％，与手术和病理对照正确率为８８．４％。结论 ＥＵ

Endoscopic ultrasonography in detecting causes of cholangiectasis

Objective The diagnostic significance of endoscopoic ultrasonography (EUS) for thecauses of cholangiectasis was studied. Methods EUS was practised on 43 patients with cholangiectasis ofunknown origin by conventional EU. The results were compared with surgical and pathological findings.Results Choledocholithiasis was confirmed in 34 cases, pancreatic head mass in 5, biliarv tumor in 2 andcongenital cholangiectasis in 1. With EUS the positive detection rate rose to 97.7% , the diagnostic accuracybeing 88.4% when compared with that of surgery and pathology. Conclusion EUS is quite significant indifferentiating the causes of cholangiectasis, may be more sensitive in dealing with fine stones than conven-tional US.
