摘要
目的以了解垸内水网型疫区血吸虫病病情，并探讨B超对人群病情评估的价值。方法在垸内水网型疫区，对732名当地居民进行B超检查，同时进行Kato－Katz法、孵化法检查粪便和病史询问。结果该地居民粪检阳性率44．76％，肝实质Ⅰ级以上男性53．31％，女性49．19％，Ⅱ级以上男性17．68％，女性8．65％。门静脉内径异常男性25．69％，女性11．08％。男女感染率无差别，但男性肝脾异常明显高于女性。血吸虫感染与未感染者相比较，肝实质、门静脉内径、肝右叶斜径，女性还包括肝左叶长径、厚径等指标均高于未感染者。结论本研究提示：境内水网型疫区病情控制应引起足够重视。B超能直接评价血吸虫病引起的肝脾损伤。
Objectives To learn the morbidity of schistosomiasis in dam-circle marsh region,and evaluate the ultrasound to be used in assessment of the morbidity of the disease. Methods All residents aged 3-70 in 6 village groups were examined by methods of ultrasound,Kato-Katz as well as stool hatching test. Results The positive rate of fecal examination was 44. 76 %,and 53. 31% of the malejs and 49. 19 % of the females' liver parenchyma were abnormal (≥grade Ⅰ ). The abnormal rates of portal vein diameter of the males and the females were 25. 69 % and 11.08%,respectively.The abnormal index of liver parenchyma grade,portal vein diameter,size of right lobe,left lobe size and thickness (in females only) were more serious in the infected patients than that in uninfected Qnes. Conclusion Much more attention should be paid to the morbidity of schistosomiasis in dam circle marsh regions due to its unique epidemic characters. Ultrasound can show the damages of liver and spleen in patients infected with Schistosoma japonicum directly.
