Bacteremia after hepatectomy and biliary reconstruction for biliary cancer: the characteristics of bacteremia according to occurrence time and associated complications.

Abstract

PURPOSE:

Bacteremia occurring after extensive hepatic resection and biliary reconstruction (Hx + Bx) for biliary cancer is a critical infectious complication. This study evaluated postoperative bacteremia and examined the potential usefulness of surveillance cultures.

METHODS:

We retrospectively reviewed 179 patients who underwent Hx + Bx for biliary cancer from January 2008 to December 2018 in our department.

RESULTS:

Bacteremia occurred in 41 (23.0%) patients. Patients with bacteremia had a longer operation time and more frequent intraoperative transfusion and more frequently developed organ/space surgical site infection (SSI) than those without bacteremia. The most frequently isolated bacterial species from blood cultures were Enterococcus faecium (29.3%), Enterobacter cloacae (24.4%), and Enterococcus faecalis (22.0%). The SIRS duration of bacteremia associated with organ/space SSI was significantly longer than that of other infectious complications (median 96 h vs. 48 h; p = 0.043). Bacteremia associated with organ/space SSI occurred most often by postoperative day (POD) 30. The concordance rate of bacterial species between blood and surveillance cultures within POD 30 was 67-82%.

CONCLUSIONS:

Bacteremia associated with organ/space SSI required treatment for a long time and typically occurred by POD 30. Postoperative surveillance cultures obtained during this period may be useful for selecting initial antibiotic therapy because of their high concordance rate with blood cultures.
