title: Transient bacteremia associated with percutaneous liver biopsy.
abstract: Transient bacteremia associated with percutaneous liver biopsy was studied by pour-plate blood cultures, which were obtained immediately before and after the procedure and 5, 10, 15, and 30 min later in 89 patients. Part of the liver tissue was also cultured in all patients. Histological diagnoses included hepatitis, cirrhosis, cholangitis, fatty liver, granulomata, metastatic liver disease, lymphoma, and miscellaneous disorders. All blood cultures obtained before liver biopsy were sterile. Bacteremia was demonstrable in 12 patients (13.48%). In most of these patients, blood cultures were positive for as long as 15 min after liver biopsy; all cultures were negative at 30 min. Among the bacteria associated with 12 episodes of bacteremia were Escherichia coli, Klebsiella, Bacteroides, enterococci, diphtheroids, Staphylococcus aureus, alpha-hemolytic Streptococcus, and Streptococcus pneumoniae. The patients with positive liver biopsies had a higher incidence of bacteremia (83.3%) than did the patients whose liver biopsies were sterile (8.r%); this difference is stastically significant (P smaller than 0.01). Thus, liver biopsy can be associated with transient bactermia.
