To determine the frequency and nature of complications after liver biopsy and whether risk factors could be identified to predict these complications, the medical records of all patients (age, 1 week to 28 years) who underwent a percutaneous liver biopsy at Children's Hospital over a 6-year period (1981-1986) were reviewed. Data were collected from 469 (97%) of 483 eligible charts. Twenty-one patients (4.5%) experienced major complications including bile leak (n = 3, 0.6%), prolonged drainage of ascitic fluid (n = 1, 0.2%), pneumothorax (n = 1, 0.2%), bleeding requiring transfusion (n = 13, 2.8%), and death (n = 3, 0.6%). A subgroup of patients (n = 37) with cancer or bone marrow transplantation was found to be at a nearly fivefold greater risk for transfusion than patients with other diagnoses (P = 0.02). All three deaths in previously stable patients occurred in this same high-risk group of patients with cancer or bone marrow transplantation (P < 0.001). Two deaths resulted from disseminated intravascular coagulation and one from bleeding. Diagnosis, age, number of percutaneous passes, and prebiopsy coagulation studies were not predictive of subsequent complications. It is concluded that bleeding that requires transfusion is the most common liver biopsy complication and that it occurs more frequently in children than previously reported. Children with cancer or those who have undergone bone marrow transplantation are at a greater risk for bleeding and death following percutaneous liver biopsy.
