在22～69%肝脏有转移性肿瘤的病例中,不用引导的经皮针刺活检标本中不含有肿瘤组织.但在占位性病变邻近可有组织学变化,据之应继续寻找肝脏的转移.为明确转移性肿瘤邻近肝脏组织学的变化,对20份有转移性肿瘤的肝脏针刺活检标本,就10项病理改变进行了检查.鉴于肿块造成血流和胆流阻塞被认为可能是引起邻近肝脏组织学变化的原因,另选10例肝外胆道阻塞患者的活检标本作为比较.
In 22 to 69% of cases with metastatic liver tumors, there is no tumor tissue in the guided percutaneous needle biopsy, but histological changes may be present in the vicinity of the mass lesions, whereupon liver metastasis should continue to be sought In order to clarify the histological changes of the adjacent liver in metastatic tumors, 20 pathological liver biopsy specimens with metastatic tumors were examined for 10 pathological changes, and the occlusion of the bloodstream and gallbladder was considered likely to be caused by mass Adjacent to the liver histological reasons for the change, and another 10 cases of extrahepatic biliary obstruction biopsy specimens for comparison.
