Retrospective study on the risk factors related to intraabdominal infection after anatomical hepatectomy / 中华普通外科杂志

ABSTRACT

Objective To assess the incidence and related risk factors of postoperative intraabdominal infection in patients undergoing anatomical hepatectomy.Methods The clinical data from 122 patients who underwent anatomical major hepatectomy in our institution were retrospectively analyzed.The electronic medical data were retrieved for further analysis including the amount of crystalloid and colloid fluid infused,intraoperative estimated blood loss,volume of blood transfusion,the dosage of vasoactive drugs,postoperative liver function,inflammation index,the incidence of intraabdominal infection and the length of hospital stay (LOS).Results Patients were divided into infection group (n =39) and non-infection group (n =83).Intraabdominal infection was correlated with preoperative cirrhosis,the elevated direct bilirubin and alanine aminotransferase,the duration of operation,bilioenteric anastomosis or cholangiotomy,the infusion volume of colloid and crystalloid fluid,transfusion volume,direct bilirubin level on the POD 1 (post-operation on day 1) (P ＜ 0.05);Multivariate analysis showed the incidence of intraabdominal infection was highly correlated with the amount of intraoperative colloid fluid bilioenteric anastomosis(P ＜ 0.05).Conclusions Intraoperative infused volume of synthetic colloid,along with bilioenteric anastomosis are independent risk factors for postoperative intraabdominal infection.
