摘要
目的:探讨胆管腔内超声对良恶性胆道狭窄的鉴别诊断价值.方法:2006-01/2007-01所有在我院行ERCP及IDUS检查的胆道梗阻患者67例(所有患者随访12-36mo),对比影像学诊断差异,计算IDUS的敏感性,特异性,阳性预测值,阴性预测值及准确性.结果:手术病理或者细胞学刷检证实为恶性胆管狭窄者共37例,病理阴性且长期随访证实良性胆管狭窄者共30例,IDUS对胆管恶性狭窄判断的敏感性为89.2%(33/37),特异性为77.4%(24/31),阳性预测值为82.5%(33/40),阴性预测值为88.9%(24/27),准确性为85.1%(57/67).结论:胆管腔内超声是一项安全可靠的技术,对胆管良恶性狭窄性质的鉴别有较高的价值.
AIM： To determine whether intraductal ultrasonography （IDUS） is of assistance in distinguishing benign from malignant biliary strictures. METHODS： Sixty-seven patients （all were fol- lowed up for 12-36 mo） with biliopancreatic obstruction who underwent the examination of ERCP and IDUS from January 2006 to January 2007 were analyzed, and the difference of imaging diagnosis was compared and the sensitivity, speci- ficity, positive predictive value, negative predictive value and accuracy of IDUS were calculated. RESULTS： Malignant strictures （37 patients） were confirmed histopathologically and benign stricture （30 patients） was confirmed based on negative pathology plus extended clinical fol- low-up. Sensitivity, specificity, positive predic- tive values, negative predictive values and ac- curacy of IDUS for malignant bile duct strictures were 89.2%, 77.4%, 82.5%, 88.9% and 85.1% CONCLUSION： Intraductal ultrasonography is safe and is of high value in differentiating be- nign from malignant biliary strictures.
