ABSTRACT
Introduction. Postoperative infection (POI) prolongs inpatient stay, delays return to
normal activity, and may be detrimental to long-term survival after cancer resections. This
study sought to identify the impact of postoperative infection on liver transplantation
outcomes.
Methods. We analyzed our prospective database of 910 adult patients who underwent
liver transplantation between 2000 and 2010 in a single UK center. POI was defined as
pyrexia plus positive cultures from blood, sputum, urine, wound, or ascitic fluid. Patient
demographic features and perioperative variables were analyzed for their effects on POI.
The impacts of POI on overall survival (OS) and graft survival were analyzed using
Kaplan-Meier curves with log-rank tests for significance, before entry into a multivariate
regression analysis. We analyzed the effects of POI on the length of hospital stay (LOS)
and the incidence of acute rejection episodes and readmissions within 1 year as secondary
outcomes.
Results. Patients who developed a postoperative chest or wound infection showed
poorer OS at a mean of 7.0 versus 8.8 years (P = .009) and 7.0 versus 8.8 years (P = .003),
respectively. Infection in blood, ascitic fluid, or urine showed no significant impact on
survival. LOS was significantly increased among patients with a wound (median 21 vs 17
days, P = .011), a sputum (median 24 vs 17 days, P .001), or a blood infection (median
32 vs 17 days, P .001). Higher rates of intraoperative blood transfusion were observed
among subjects who developed a chest or a wound infection. There was no difference in
other variables between those who did versus did not develop an infection. Upon
multivariate analysis, wound infection was the strongest independent predictor of OS (P =
.007).
Conclusion. We demonstrated that wound or chest infections were associated with
poorer OS. More aggressive prophylactic and/or therapeutic interventions targeting
specific sites of infection may represent a simple and cost-effective measure to reduce
hospital stay and improve OS.

OSTOPERATIVE INFECTION (POI) prolongs the
inpatient stay and delays the return to normal activity,
detrimentally impacting a patient’s postoperative course.
POI has also been shown to negatively impact long-term
outcomes following liver resection for colorectal metasta-
ses

or hepatocellular carcinoma.

Similar findings have
been demonstrated following colorectal or esophageal re-
sections.
