This is a prospective study in which 120 patients with diffuse liver disease undergoing liver biopsy were followed by serial ultrasounds to determine the incidence of postbiopsy intrahepatic hematoma formation. Forty-five of the patients had a blind biopsy, while the remaining 75 patients had a biopsy performed during laparoscopy. In both groups a 2.0-mm Tru-cut needle was employed. The overall incidence of postbiopsy hematoma formation was 18.3%, with approximately the same results occurring in blind biopsy patients (20%) and laparoscopy-guided biopsy patients (17%). Only two patients had significant pain associated with the hematoma formation (one from each group), one of whom had evidence of intraperitoneal bleed and rebleed. Our results suggest that postbiopsy asymptomatic hematomas occur more frequently than had been generally thought and that laparoscopy-guided biopsy is not safer than blind biopsy.
这是一项前瞻性研究，对120例接受肝脏活检的弥漫性肝病患者进行系列超声检查，以确定活检后肝内血肿形成的发生率。其中45例患者接受盲目活检，其余75例患者在腹腔镜检查期间进行活检。两组均使用2.0毫米Tru-cut针。活检后血肿形成的总发生率为18.3%，盲目活检患者（20%）和腹腔镜引导活检患者（17%）的结果大致相同。只有两名患者因血肿形成出现明显疼痛（每组各一名），其中一名有腹腔内出血和再出血的证据。我们的结果表明，活检后无症状血肿的发生比一般认为的更频繁，并且腹腔镜引导活检并不比盲目活检更安全。
