摘要:
目的评价肝穿刺活组织检查在肝病诊断及治疗中的价值。方法回顾性分析浦东新区南华医院自2007年以来接受B超定位下行1秒钟(1s)肝穿刺诊断并指导治疗患者的情况。结果 16例不明原因肝损伤的患者经肝穿刺活组织检查明确诊断,药物性肝炎4例(4/16,25%),脂肪性肝炎4例(4/16,25%)自身免疫性肝炎2例(2/16,12.5%),乙型肝炎2例(2/16,12.5%),急性淤胆型肝炎、血吸虫性肝病各1例,2例经肝穿活检仍未能明确诊断。在20例反复肝功能异常半年以上、ALT<2倍正常上限值(2×ULN)、高病毒载量的慢性乙型肝炎(CHB)患者中,有65%(13/20)肝脏炎症指数≥2级,需抗病毒治疗,且年龄20~40岁者占69.2%(9/13)。结论肝穿刺活检是诊断肝功能异常病因的重要手段,对明确诊断并确立最适当的治疗方案有重要价值。
Abstract:ObjectiveTo assess the clinical significance of liver biopsy for diagnosis and treatment of liver disease. MethodsPatients with obscure liver disease who underwent liver biopsy under B-ultrasound guidance at our hospital between 2007 and 2011 were retrospectively analyzed. ResultsSixteen cases with obscure liver disease were diagnosed after liver biopsy. Among them, four cases (25.0%) were diagnosed as drug induced hepatitis, four (25.0%) as fatty liver disease, two (12.5%) as autoimmune hepatitis, two (12.5%) as hepatitis B virus infection, one (6.3%) as acute viral cholestatic hepatitis, and one (6.3%) as Schistosomiasis liver disease. In the two remaining cases (12.5%), no specific diagnosis was confirmed by the liver biopsy. Among the 20 chronic hepatitis B patients (all of whom presented with abnormal liver function at six month follow-up, high viral load, and alanine aminotransferase (ALT) level lower than twice the upper limit), 13 (65.0%) had at least moderate intensity hepatic inflammation (greater than or equal to grade II) that necessitated antiviral therapy. Furthermore, the majority (69.2%) of these patients represented the 20-40 year-old age category. ConclusionLiver biopsy is an important approach for diagnosing the cause of liver function abnormalities and plays an important role in designing a suitable treatment strategy.
