经皮肝穿刺胆道造影术下胆管活检的临床研究

目的　探索经皮肝穿刺胆道造影术 (PTC)下胆道活检的可行性和敏感性。方法　 31例阻塞性黄疸患者 ,在行经皮经肝穿刺胆道内外引流术 (PTCD)中 ,进行PTC下胆道活检。通过经皮经肝胆道穿刺通道向胆道内送入 8F鞘 ,活检钳经鞘内送入并对病变狭窄段行胆道钳夹活检 ,获取多个标本 ,行组织病理学检查。结果　 31例患者 30例获得组织病理学诊断 (敏感性 96 .8% )。结论　PTC下胆道活检是一种简单易行、准确可靠的获取组织学病理检查途径

New way in pathologic diagnosis of biliary obstructive jaundice: a clinical study in percutaneous transhepatic cholangiobiopsy

Objective To explore the technical feasibility and sensitivity of percutaneous transhepatic cholangiobiopsy in malignant obstructive jaundice, together with the guidance for clinical managements.. Methods 31 patients with obstructive jaundice after percutaneous transhepatic cholangiography and drainage were undesgone percutaneous transhepatic cholangiobiopsy. The technique was performed through an preexisted percutaneous transhepatic tract with a 8 Frerch sheath, multiple specimens were obtained after passing the forceps for the biopsy. The specimens were fixed with formalin, and then taken for histopathologic diagnosis. Results The histopathologic diagnosis was acquired in 30 of 31 patients(sensitivity, 96.8%). Conclusions Percutaneous transhepatic cholangiobiopsy is an accurate, safety and reliable way, easy to perform with a histopathologic diagnosis sensitivity rate of 96.8%.
