尽管经皮直视针吸能获得一个肝核心活检,但不及使用腹腔镜引导下所获得肝楔形活检更简便。而使用电烙术自一叶肝边缘取肝楔形组织时,由于广泛使用电烙止血,为保证标本的切除有可能造成标本的破坏。除此之外,使用腹腔镜缝合肝的边缘获得止血的效 Although a core biopsy of the liver can be obtained with percutaneous direct needle energy absorption, it is not as easy as using a laparoscopic guided liver wedge biopsy. When electrocautery is used to take the hepatic wedge tissue from the liver edge of a leaf, electrocautery and hemostasis are widely used. In order to ensure the removal of the specimen, the specimen may be destroyed. In addition, the use of laparoscopic suture of the liver to achieve hemostatic effect
