目的分析胆囊结石合并华支睾吸虫感染患者的超声影像学特点,探讨其临床诊断价值。方法回顾分析2009年1月—2012年12月间2 886例胆囊结石患者中同时有华支睾吸虫感染者(以胆汁中发现虫卵为诊断依据)的肝、胆超声声像学特点及二者的关系。结果所有胆囊结石患者中,华支睾吸虫感染率43.3%(384/886)。与之相比,超声出现除胆囊结石外的额外声像比例为33.6%(298/886),两者差异有统计学意义(χ~2=26.455,P<0.05),其总的敏感性和特异性为43.0%(165/384)和73.5%(369/502)。额外声像的种类及其敏感性和特异性分别是:肝实质增粗和,或肝内外胆管壁增厚为6.0%和99.6%;胆囊壁增厚(≥3 mm)和/或胆囊增大为10.4%和93.2%;胆囊炎症表现为12.5%和91.8%;胆泥、胆囊沉积物和/或泥沙样结石为26.3%和85.1%。结论胆囊结石患者合并华支睾吸虫感染时,肝胆超声会出现除胆囊结石外的额外声像,但用于临床诊断敏感性不足。
Objective To analyze the imaging features of gallbladder stones associated with Clonorchis sinensis infection and explore its clinical value. Methods The liver and gallbladder sonographic characteristics of 2 886 patients with gallbladder stones who were infected with Clonorchis sinensis at the same time from January 2009 to December 2012 were analyzed retrospectively. Relationship. Results In all patients with gallstone, the infection rate of Clonorchis sinensis was 43.3% (384/886). In contrast, there was 33.6% (298/886) cases of extra sonography in addition to gallbladder stones, the difference was statistically significant (χ ~ 2 = 26.455, P <0.05). The overall sensitivity and Specificities were 43.0% (165/384) and 73.5% (369/502). The types of extra pancreas and their sensitivity and specificity were: thickening of the liver parenchyma, or extrahepatic bile duct wall thickening of 6.0% and 99.6%; gallbladder wall thickening (≥3 mm) and / or gallbladder enlargement Were 10.4% and 93.2% respectively; gallbladder inflammation was 12.5% and 91.8%; bile sludge, gallbladder deposits and / or sediment-like stones were 26.3% and 85.1% respectively. Conclusion Gallbladder stones combined with Clonorchis sinensis infection, extrahepatic cholecystolithiasis will appear extra sound image, but for the clinical diagnosis of inadequate sensitivity.
