title: Infections associated with transhepatic biliary drainage devices.
abstract: To determine the infectious complications associated with transhepatic biliary drainage devices, an analysis of the records of 38 patients who underwent placement of a pigtail catheter (n = 11), a Ring catheter/feeding tube (n = 13), or a Carey-Coons endoprosthesis (n = 15) was carried out. Nineteen infectious events occurred in 38 patients with 39 biliary devices. Infections consisted of bacteremia, cholangitis with and without documented bacteribilia, and intrahepatic abscesses and were frequently associated with obstruction (66.7 percent of infectious episodes). The most frequent organisms isolated from blood were Escherichia coli and Pseudomonas aeruginosa, and the most frequent organisms isolated from bile were P. aeruginosa, Klebsiella pneumoniae and Streptococcus faecalis. Trends for more frequent occurrence of neoplasms involving the gallbladder or biliary tract, recent surgical procedures and catheter manipulations in infected as compared with noninfected patients, and a delayed time to infection were noted in patients with an endoprosthesis.
