摘要
目的:探讨B超、ERCP、CT检查对梗阻性黄疸的鉴别诊断价值。方法:对经手术及病理证实的120例梗阻性 黄疸的B超、ERCP、CT检查对比分析,讨论各检查方法的优点和局限性。结果:B超检查对胆管梗阻病变的定位诊断的 准确性较高,但定性诊断的准确性较低;CT检查的定位、定性诊断的准确性较高,但定性诊断的准确性比ERCP低; ERCP检查对梗阻性黄疸病因定位、定性诊断的准确性优于B超和CT检查,特别是对发生在胆管下段梗阻病变诊断和 鉴别诊断的准确性较高,并可通过直视及活检确诊乳头癌。结论:梗阻性黄疸病人应首选B超检查,将其作为筛选病例的 首选方法;B超检查难以确诊的则选用CT、ERCP检查,其中以ERCP检查的诊断准确性较高,为较好的检查方法。
Objective To study the diagnostic value of ultrasound, ERCP and CT on obstructive jaundice. Methods One hundred and twenty patients with obstructive jaundice confirmed by operation and pathology were compared and analysed to find out the advantages and limitations when using the different checking methods. Results Ultrasound had a higher diagnostic accuracy in location,but lower accuracy in qualitative analysis. CT had more advantages in both,and ERCP had even more advantages than ultrasound and CT,especially in diagnosing obstructive jaundice stenosis below the bile duct. Moreover,the papillary cancer could be correctly diagnosed with ERCP. Conclusion Ultrasound is the first choice to screen the obstructive jaundice. CT and ERCP can be a help when it's hard to make a diagnosis. Of the three methods,ERCP is the best.
