Abstract

ABSTRACT Cholestasis jaundice results from diminished bile flow and/or excretion, and caused by a number of disorders such as biliary atresia (BA). Magnetic resonance cholangiopancreatography (MRCP) is widely accepted as one of the modalities for biliary system imaging; however, liver biopsy still generally used for BA diagnosis, especially in developing countries. This aim study was to evaluate the diagnostic value of biliary atresia from MRCP compared to the result of a liver biopsy. A cross-sectional for diagnostic study documented of hospitalized patients from June 2014 to June 2015. All patients had MRCP and liver biopsy examination. The collection of data including age, gender, clinical manifestation and the result of MRCP and liver biopsy with ROC to evaluate the sensitivity and specificity was done. Liver biopsy revealed of biliary atresia was made based on proliferation, degeneration, and fibrosis of bile ducts. ROC to evaluate the sensitivity and specificity was done. The sensitivity, specificity, negative predictive value, positive predictive value of MRCP in diagnosing BA were calculated. There were 16 patients enrolled in this study with a median age of diagnosis was 6 months old (range 3-11). There were nine female patients out of the 16 patient. The median age of jaundice onset was 5 days (range 2-14 days). All patients had hepatomegaly and splenomegaly. Histopathology from liver biopsy revealed biliary atresia in 12 patients. From the ROC curve, the sensitivity of MRCP was 87.5% and specificity 62.5% with PPV 70% and NPV 80%. Five patients underwent a Kasai procedure and revealed biliary atresia.

磁共振胆管造影作为诊断工具在soetomo医生医院诊断胆道闭锁
胆汁淤积性黄疸是由胆汁流量和/或排泄减少引起的,由胆汁闭锁(BA)等多种疾病引起。磁共振胰胆管造影(MRCP)被广泛接受为胆道系统成像的一种方式;然而,肝活检仍然普遍用于BA的诊断,特别是在发展中国家。本研究旨在评价MRCP与肝活检对胆道闭锁的诊断价值。对2014年6月至2015年6月住院患者进行横断面诊断研究。所有患者均行MRCP和肝活检检查。收集年龄、性别、临床表现、MRCP及肝活检结果等资料,采用ROC评价敏感性和特异性。肝活检显示胆管增生、变性及纤维化为胆道闭锁。采用ROC法评价其敏感性和特异性。计算MRCP诊断BA的敏感性、特异性、阴性预测值、阳性预测值。本研究纳入了16例患者,中位诊断年龄为6个月(范围3-11)。16例患者中女性9例。黄疸发病的中位年龄为5天(范围2-14天)。所有患者均有肝脾肿大。肝组织病理检查显示12例胆道闭锁。从ROC曲线上看,MRCP的敏感性为87.5%,特异性为62.5%,其中PPV为70%,NPV为80%。5例患者行Kasai手术后发现胆道闭锁。MRCP对BA诊断敏感但不特异性,MRCP对BA诊断有中等敏感性和特异性。关键词:胆道闭锁,磁共振胆管造影,肝活检,诊断试验。通讯:geendjk@gmail.com摘要:ikterus dikarenakan kolestasis terjadi akibat berkurangnya aliran empdu dan/ atau ekskresi, dan dapat disebabkan oleh sejumlah gangguan seperti atresia bililiaris (BA)。磁共振胰胆管造影(MRCP)诊断先天性胆管病变、先天性胆管病变、先天性胆管病变、先天性胆管病变、先天性胆管病变诊断、先天性胆管病变、先天性胆管病变、先天性胆管病变。本研究对胆道闭锁的MRCP诊断进行了回顾性研究。西布亚横断面骨突研究诊断,于2014年6月1日至2015年6月1日进行。Semua pasen menjalani MRCP和peremeriksaan biopsi hati。数据分析,jenis kelamin, manifestasi klinis, hasil MRCP和biopsi, dengan, ROC untuk,敏感性评估和特异性诊断为dilakukan。胆道组织增生、退行性变性、纤维化和腹腔空化。用ROC积分法评价其敏感性和特异性。dilakkan perhitungan敏感性、特异性、MRCP阴性预测值、MRCP阳性预测值均为BA。6例(3-11),诊断为慢性肾衰竭。terapat有9个永久居民,16个永久居民。美国按比例发病的penyakit kuning adalah 5 (kisaran 2-14) hari。肝脾肿大。组织病理学及活检检查显示:12例,16例。达里库尔瓦ROC,敏感性MRCP达87,5%,特异性62,5%,邓安PPV为70%,NPV为80%。利马的检察官卡西丹·蒙贡卡坎·阿特利亚。MRCP的敏感性与特异性诊断BA不同,MRCP的敏感性与特异性诊断BA不同。卡塔昆兹:胆道闭锁,磁共振胰胆管造影,肝活检,诊断试验。Korespondensi: geendjk@gmail.com
