摘　　要：目的探讨超声检查在肝外胆管梗阻病因诊断中的应用价值。方法 203例肝外胆管梗阻性疾病患者,超声沿胆总管走向从肝门部扫查至胆总管下段,依据管道扩张情况判断梗阻或狭窄部位,观察病变大小及其与周围组织的关系,并与手术病理结果进行对比,总结不同病因导致肝外胆管梗阻的声像图特点。结果 203例患者,胆总管中、下段清晰显示165例,显示率为81.3%,超声诊断与手术病理结果符合173例,符合率为85.2%,漏误诊30例。结论超声检查有助于明确病变部位、性质及其与周围组织的关系,可作为肝外胆管梗阻的首选影像学检查。Objective To investigate the value of ultrasound in etiological diagnosis of extrahepatic biliary obstruction. Methods Two-hundred and three cases of extrahepatic bile duct obstruction were examined with routine ultrasonography, the common bile duct （CBD） was imaged from the hepatic hilum to the distal part, the positon of obstruction or stenosis was judged according to the dialtion of CBD, the size of the lesions and the relationship with the surrounding tissue were observed. The results were compared with operation pathological results, the different etiology characteristics of extrahepatic bile duct obstruction were summarized. Results In 203 cases, the middle and distal segment of CBD was clearly displayed in 165 cases with the display rate of 81.3%, the ultrasound diagnosis was coincident with pathological results in 173 cases with the coincidence rate of 85.2%. 30 cases were misdiagnosed and missed diagnosed. Conclusion Ultrasound can help to identify the position, characteristics of lesions and the relationship with surrounding tissue, it may be the first line imaging examination for extrahepatic bile duct obstruction.
