B超及B超引导下PTC在胆系结石诊断中的对照研究

B-MODE ULTRASOUND STUDY COMPARED WITH ULTRASOUNICALLY GUIDED-PTC FOR THE DIAGNOSIS OF BILIARY CALCULI

目的 评价 B超与 B超引导下 PTC(经皮肝穿刺胆管造影 )对胆系结石病人诊断的价值。方法 对 B超与 B超引导下PTC2 2 1例经手术及病理证实的胆系结石病人进行分析对照。结果 PTC诊断胆总管下段结石符合率为 98.0 2 % ,超声显像诊断胆总管下段结石符合率为 82 .18% ,二者相差非常显著 (P<0 .0 1)。而 B超对肝内胆管结石的诊断符合率是 95 .2 4% ,PTC诊断肝内胆管结石的诊断符合率是 71.43% ,二者相差显著 (P<0 .0 5 )。结论 B超与

Objective To evaluate the B-made ultrosound and ultrasounically guided-PYC for the patients with biliary calculi.Methods The biliary calculi in 221 patients which confirmed by operation and histopathology were studied by B-mode ultrosound technique.The efficacy was compared with ultrasonically guided-PTC.Results The results showed that PTC diagnostic accuracy was 98.02% in inferior common bile duct stone,and superior to ultrasonography(82.18%,P<0.01),but B-mode ultrasound diagnostic accuracy was 95.24% in calculus of intrahepatic duct and better than PTC(71.43%,P<0.05).Conclusion It suggested that B-mode ultrasound and PTC can help each other in the diagnosis of biliary calculi.
