title: Transjugular and plugged liver biopsies.
abstract: When a liver biopsy is indicated the transabdominal approach using either a Menghini or Tru-Cut needle has been shown to be an extremely safe procedure with very low morbidity and mortality rates in patients with normal or only mildly disturbed coagulation. When the coagulation status is severely deranged, however, several methods of obtaining a liver biopsy have been devised to circumvent the increased risk of bleeding. The transjugular approach has been shown to be both successful and relatively safe. The less cumbersome technique of plugging the needle track after percutaneous transabdominal biopsy has been reported relatively recently. Although it is likely that the latter method will produce good biopsy samples in the majority of cases (and in this regard it may prove to be better than the transjugular route), considerably more experience is required before its true complication rate is known. In a hospital where large numbers of transjugular biopsies are performed by experienced radiologists and in which skilled pathologists are used to interpreting the histological appearances of small, crushed liver samples, there is no compelling reason to change to the plugged biopsy technique. The more difficult question is whether hospitals in which the radiological and histological skills necessary for consistent success with the transjugular approach are not available should adopt the plugged biopsy method. The answer to this question is probably in the affirmative, but will depend on the confidence and interventional experience of the local operator and on more detailed factual information concerning the safety of the plugged method. With regard to the latter point, the publication of a large controlled study on the safety and efficacy of plugged liver biopsy would be a valuable contribution to the world literature on the subject.
