title: [Evaluation of bile diffusion of piperacillin].
abstract: In 10 patients undergoing cholecystectomy peroperative samples of serum, bile and gall bladder tissue were obtained one hour after intravenous injection of 2 g of piperacillin. Measurements were made by high performance liquid chromatography. Mean concentrations of piperacillin were 81.7 +/- 13.6 micrograms/ml in serum (S), 382 +/- 110 micrograms/ml in choledochal bile (CB), 30.8 +/- 8.5 micrograms/ml in gall bladder bile and 10.5 +/- 2.6 micrograms/g of gall bladder tissue. With a CB/S ratio of 4.7, piperacillin may be classified among beta-lactams showing good distribution in the biliary tract. This property would make piperacillin useful against the pathogens usually responsible for biliary tract infections.
