胰胆管内超声与体表超声相结合诊断胆管疾病

The efficacy of the combination of intraductal-and extra corporeal ultrasonography for diagnosing biliary duct diseases

目的探讨胰胆管内超声与体表超声结合对提高胆管病变的诊断价值。方法回顾性研究体表超声检查未能明确诊断而行腔内超声检查的住院患者40例,胰胆管内超声(IDUS)以内镜逆行胰胆管造影(ERCP)作为基本方法,通过将造影导管向胆管或胰管内深部插入,交换导丝后,在导丝引导下向胆管或胰管内插入探头显示图像。结果 IDUS检查与手术病理诊断符合37例,漏误诊3例,诊断准确率为92.50%。结论体表超声与腔内超声相结合,可有效提高胆管病变诊断的准确率,便于更多胆管病变的早期发现。

Objective To explore the efficacy of the combination of extracorporeal-and intraductal ultrasonography（IDUS） for diagnosing biliary duct diseases.Methods Forty patients with biliary duct diseases,who undenwent IDUS because of indefinite diagnosis on previous extracorporeal ultrasonography were retrospectively studied.The endoscope was passed deeply into bile ducts or pancreatic ducts and the catheter was inserted into the ducts with the direct of guide wire according to endoscopic retrograde cholangiopancreatography（ERCP） as a primary method of IDUS.Results Preoperative IDUS correctly diagnosed 37 out of 40 patients,leakily and misdiagnosed 3 out of 40 patients,so that the coincident rate with pathology was 92.5%.Conclusion The mutual complementarity of extracorporeal and intraductal ultrasonography can improve the diagnostic accuracy of biliary duct diseases and benefit earlier discovery of the diseases.
