Abstract
The aim of this study was to observe the correlation between liver biopsy bleeding time, prothrombin time ratio and platelet count. The subjects were 51 consecutive patients referred for laparoscopic liver biopsy. The intervention was laparoscopy under local anaesthetic and liver biopsy with observation of post biopsy bleeding time. No correlation was found between observed liver biopsy bleeding time and platelet count or prothrombin time ratio. Thus, mild to moderate coagulopathy does not appear to be associated with prolonged bleeding following liver biopsy. Equally, normality of these coagulation studies does not indicate an absence of risk for post liver biopsy bleeding.
