【摘要】 目的:探索 PTC 胆道活检与 PTC 影像学特征的相关关系及对阻塞性黄疸的诊断价值。方法回顾性分析资料完整并接受 PTCD 和胆道内支架置入治疗及 PTC 胆道活检的连续81例阻塞性黄疸病例,用 Spearman 检验比较 PTC 胆道活检与 PTC 影像学特征的相关关系。结果:PTC 胆管阻塞长度<2cm 者的胆道活检阳性率低于胆管阻塞长度为2～4cm 和>4cm 者的阳性率 (H=10.176,P=0.006<0.05)且呈正相关关系(rs=0.320,P=0.002<0.05),PTC 胆管重度扩张者的胆道活检阳性率高于胆管中度和轻度扩张者的阳性率(H=7.616,P=0.022<0.05)且呈正相关关系(rs=0.297,P=0.04<0.05),PTC 胆管活检阳性率与 PTC 阻塞形态部位和程度无相关关系。结论:PTC 阻塞段长度和肝内二级胆管扩张程度与 PTC 胆道活检成正相关关系,且对 PTC 胆道活验具有一定程度的影响。更多还原

【Abstract】 Aim To explore the correlation and diagnostic value between percu- taneous transhepatic cholangiobiopsy and PTC imaging feature in obstructive jaundice. Methods 81 consecutive patients were analyzed retrospectively with obstructive jaundice underwent PTCD and placement of stent and percutaneous transhepatic cholangiobiopsy.The correlation between percutaneous transhepatic cholangiobiopsy and PTC were compared with Spearman test.Results The positive rate of percuta- neous transhepatic cholangiobiopsy with the length of obstructive segment < 2cm was lower than that of 2～4cm and >4cm length in PTC(H=10.176,P=0.006<0.05) and has a positive correlation(rs= 0.320,P=0.002 < 0.05),The positive rate of per- cutaneous transhepatic cholangiobiopsy with server dilated bile duct in PTC was higher than that of medium and minor dilated bile duct(H=7.616,P=0.022 < 0.05) and has a positive correlation(rs= 0.297,P=0.04 < 0.05).There was no correlation between percutaneous transhepatic cholangiobiopsy and obstructive modality,ob- structive location and obstructive degree of hepatic bile ducts in PTC.Conclusion The length of obstructive segment and dilated degree of hepatic bile ducts have a positive correlation and a certain extent influence on Percutaneous transhepatic cholangiobiopsy.更多还原
