Abstract
A total of 170 therapeutic biliary drainage procedures were carried out in 90 patients with cancer over a 1-year period (January–December 1988). There were 129 percutaneous transhepatic biliary drainage procedures done in 61 patients and 41 endoprostheses were placed in 29 patients. The overall infection rate related to these procedures was 60.6%, the rate being similar for the two procedures. Infectious complications were experienced by 50% of patients undergoing a biliary drainage procedure. The most common manifestation was cholangitis followed by bacteremia. Other infections included liver abscess, gallbladder abscess, and subphrenic abscess. The most common isolates were enteric gram-negative bacilli, followed by Enterococcus species, Candida species, and Staphylococcus epidermidis. The use of prophylactic antibiotics in 76% of infected patients failed to prevent biliary catheter-related infections. Two patients died of complications related to biliary sepsis. All other infected patients responded to antimicrobial therapy, which included various regimens of β-lactam agents (third-generation cephalosporin, extended-spectrum penicillin, imipenem-cilastatin, and aztreonam) that were used in combination with an aminoglycoside in 15 patients.
