梗阻性黄疸的超声诊断

Ultrasound diagnosis of obstructive jaundice

目的探讨梗阻性黄疸的超声表现,以提高超声对梗阻病因的诊断符合率。方法结合手术病理结果,分析115例梗阻性黄疸的声像图特点。结果梗阻部位诊断符合率96.5%,梗阻病因诊断符合率89.6%。超声确诊103例(89.6%),误诊或漏诊12例(10.4%)。结论超声既能明确病变部位,又能了解病因,是梗阻性黄疸的诊断及鉴别诊断的首选方法。

Objective To study the ultrasonic manifestations of obstructive jaundice to improve the ultrasound diagnostic coincidence rate of obstructive causes.Methods Combined with surgical pathological results,the ultrasonographic characteristics in 115 cases of obstructive jaundice were analyzed.Results The diagnostic coincidence rates were 96.5% for obstructive sites and 89.6% for the obstructive causes.103 cases were definitely diagnosed by ultrasound,accounting for 89.6%,misdiagnosis or missed diagnosis was in 12 cases（10.4%）.Conclusion Ultrasound can not only clear the lesion sites,but also understand the reasons,which is the preferred method for the diagnosis and differential diagnosis of obstructive jaundice.
