Early Postoperative Infections After Liver Transplant.

OBJECTIVES

Despite surgical advances and effective prophylactic strategies in liver transplant, infection is still a major cause of morbidity and mortality. Up to 80% of liver recipients will develop at least 1 infection during the first year after liver transplant. The spectrum and manifestations of these infections are broad and variable. Their diagnosis and treatment are often delayed because immunosuppressive therapy diminishes inflammatory responses. However, if an infection is not identified early enough and treated properly, it can have devastating consequences. In addition, prophylactic approaches remain controversial. Our aim was to review our early postoperative infection management after liver transplant.

MATERIALS AND METHODS

We retrospectively evaluated infections that occurred during the first hospital stay of transplant patients. Infections were grouped as surgical site and nonsurgical site infections. Consequences and treatment protocols of infections were stratified according to the Clavien scale.

RESULTS

Between December 1988 and January 2017, we performed 561 liver transplants at our center (patient age range, 6 months to 64 years), which included 401 living-donor (72%) and 160 deceaseddonor (28%) liver transplants. Early postoperative infections were detected in 131 patients (23.3%), comprising 67 surgical site (51%), 56 nonsurgical site (43%), and 8 combined surgical and nonsurgical site infections (6%). Although no mortalities occurred in patients with single nonsurgical or surgical site infections, there were 4 mortalities in patients with combined surgical and nonsurgical site infections. In the 4 other patients with combined infections, 3 patients required endoscopic or radiologic intervention and 1 recovered from single-organ dysfunction.

CONCLUSIONS

Initiation of appropriate prophylactic and therapeutic protocols at the right time decreases morbidity and mortality due to infection in liver transplant recipients. Increased understanding and effective approaches to prevent infection are essential to improving both graft and recipient survival.
