title: Transjugular biopsy of the liver.
abstract: Percutaneous liver biopsy is the procedure of choice for most patients because of its simplicity and the high percentage of adequate biopsies obtained. It is a bedside procedure that does not require specialized equipment or the services of a highly trained angiographer. Nevertheless, complications are not uncommon unless strict contraindications are observed. It is usually recommended that patients be excluded who present with ascites, a prothrombin time less than 50%, a partial thromboplastin time greater than 10 s, or a platelet count less than 50 000. Mahal et al (1979) cite lack of attention to the contraindications as the most important factor in 22 bleeding episodes which occurred following 3800 percutaneous biopsies (0.7%). It is these contraindications that are the main indication for transjugular biopsy. Despite the highly selective nature of the patients who have undergone transjugular biopsy, the frequency of post-biopsy bleeding is only 0.35% and of death 0.13% (Table 1). These figures include the earliest experiences with this technique and can be expected to improve with increased experience and the development of new instruments that make the procedure safer and easier. Transjugular liver biopsy should be an essential procedure in every hospital that is involved in treating patients with liver disease. Unfortunately, although Lebrec et al (1982) estimated that approximately 30% of patients are rejected for percutaneous biopsy because of the presence of contraindications, relatively few centres have adopted this technique. This may be in part due to the reluctance of clinicians to subject their patients to a procedure they perceive as stressful, although a study by Poynard and Lebrec (1982) showed patients rated transjugular biopsy as less painful and inconvenient than percutaneous biopsy.
