目的调查慢性乙型肝炎(CHB)患者中肝脏良性占位性病变的发病率,以普通人群为对照,分析其高发的风险因素及其与小肝癌的鉴别要点。方法回顾性分析2016年1月~2017年12月于南方医院肝脏中心就诊的17 721例CHB患者的影像学资料及相关临床资料,与同期在南方医院健康管理中心行常规体检的21629例普通人群进行比较分析。结果与普通人群相比,CHB患者的肝囊肿、肝血管瘤、肝硬化结节发病率更高,局灶性结节性增生的发病率更低(分别为11.8%vs 8.7%、8.2%vs 1.6%、20.6%vs 2.4%、0.006%vs 0.042%,均P0.05)。肝囊肿和肝硬化结节的发病率随年龄增长而升高,其中男性发病率高于女性(P0.05)。肝脏良性占位的超声表现多为内部回声均匀,边界清晰,形态规则:肝血管瘤常为高回声(83.32%,1579/1895),与小肝癌相比,它的四周与内部血流信号较少,固有动脉流速更低,门静脉流速更高;肝硬化结节多为强、弱混合回声(79.60%,7637/9595),结节内部和周边无血流信号,当其体积增大,伴内部回声发生不均匀改变时,提示恶变概率升高;肝囊肿常表现为内部无回声,后方回声增强。结论CHB患者较普通人群更易发生肝囊肿、肝血管瘤和肝硬化结节;其发病率与年龄、性别相关。本研究总结的肝脏良、恶性占位,特别是肝硬化结节的超声声学和血流学特征,能够为早期识别肝脏占位的性质提供重要线索和依据。

In this study we analyzed blood samples collected from 400 high risk patients for the prevalence of an inflammatory viral disease hepatitis B virus (HBV) and hepatitis C virus (HCV) with the help of standard kit assay and Enzyme-linked immunosorbent assay (ELISA). All the samples were selected randomly from the various places of District Gujrat, Pakistan. All the selected cases were first divided into four groups according to the age and sex (Group 1, Male below age 35 years;Group 2, Male above age 35 years;Group 3, Female below age 35 years;Group 4, Female above age 35 years), each group was comprised of 100 individual patients and analyzed for different parameters for the presence of HBV and HCV in comparison with positive and negative controls. The prevalence of HBV and HCV was higher in groups 2 (22%) and 4 (39%) respectively. Assay profile revealed that the incidence of HCV was higher in female patients as compare to the male patients. The present study indicates that more than 60% of the cirrhosis and hepatocellular carcinoma in the Region is attributable to hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.
