肝包虫囊肿术后肝脏形态的变化特点

Characteristics of Liver Morphologic Change after Operation on Liver Hydatid Cyst Diseases

目的 了解肝包虫囊肿手术摘除后肝脏形态的变化特点。方法 对 3 44例B超诊断并经手术病理证实的肝包虫囊肿术后肝脏的超声图像特征进行了分析研究。结果 术后肝脏形态变化取决于术前肝包虫的部位和大小 :一般右肝包虫引起肝右叶缩小或消失 ,肝左叶再生增大 ;左肝包虫则肝左叶缩小或消失 ,右肝再生增大。往往包虫越大 ,萎缩与再生就越明显。肝脏的萎缩与再生是在包虫生长过程中形成的 ,术后肝脏的形态结构将不会再改变。结论 肝包虫囊肿是肝脏的良性占位性疾病 ,不管包虫多大 ,压迫多么严重 ,部分肝叶总能通过再生保持正常的肝脏体积和肝脏功能 ,术后肝脏形态的变化就清楚地说明了这一点。

Objective To learn the characteristics of liver morphologic change after operation on liver hydatid cyst diseases. Methods A study was made on the features of ultrasonic images of postoperative liver morphosis of 344 patients with liver hydatid cyst diagnosed by ultrasound and confirmed by operation and pathology. Results The liver morphologic change after operation depended upon the localities and size of the cysts before the operation. Generally,the right liver cysts caused the atrophy or disappearance of the right liver lobes and regeneration of left lobes,while the left liver cysts led to the atrophy or disappearance of the left liver lobes and regeneration of right lobes.The bigger the cysts,the more obvious this kind of phenomena.The atrophy and regeneration were formed during development of the cysts,so there would be no longer any changing taking place in the postoperative liver morphosis. Conclusion Liver hydatid cyst is one of the benign space occupying lesion in liver.No matter how big of the cysts or how severe of its pressure to the liver tissue is,the amounts of the liver cells and the liver functions can always be kept in normal condition by the regeneration of partial liver lobes. It can be clearly indicated by the change of postoperative liver morphology.
