Abstract:
Objective:To study the risk factors and microbial spectrum for infectious complications for patients with biliary tract cancer after major hepatectomy with cholangiojejunostomy.Methods:Enrolled into this study were 78 consecutive patients (57 patients with perihilar cholangiocarcinoma, 17 with intrahepatic cholangiocarcinoma and 4 with gallbladder cancer), who underwent major hepatectomy with cholangiojejunostomy at Nanjing Drum Tower Hospital between September 2010 and March 2019. The clinical data were reviewed using multivariate analysis to find independent risk factors for postoperative infectious complications. Microorganisms isolated from bile and infected sites were determined to study the microbial spectrum.Results:A total of 45(57.7%) patients suffered from postoperative infectious complications. Male sex ( OR=7.765, 95% CI=1.895-31.815, P<0.05) was the independent risk factor, whereas increased preope-rative red blood cell (RBC) ( OR=0.151, 95% CI=0.038-0.592, optimal cut-off value=3.7×10 12/L) and increased total cholesterol (TC) on postoperative day (POD) 1 ( OR=0.227, 95% CI=0.083-0.626, optimal cut-off value=3.5 mmol/L) were protective factors (both P<0.05). The area under the receiver operating characteristic (ROC) curve was 0.805 (95% CI=0.707-0.902, P<0.05). 205 and 230 microorganisms were cultured respectively from 286 and 681 specimens which were collected from pre-/intraoperative bile and potentially infected sites. Staphylococcus, enterococcus, acinetobacter, klebsiella and pseudomonas were the most common pathogens on bile culture. The first 5 most frequently isolated microorganisms from the infected sites were enterococcus, staphylococcus, klebsiella, candida and xanthomonas. Sixteen (61.5%) of 26 patients had at least one pathogen being isolated from the infected sites with the pathogen being previously isolated in bile culture. Conclusions:Male sex were independent risk factors of infectious complications. Increased preoperative RBC and inreased TC on POD were proteetive factors. For patients without a positive bile culture, a third-generation cephalosporin can be considered as a prophylactic antibiotic. It is important to identify high-risk patients and monitor perioperative pathogens actively to prevent and to cure postoperative infectious complications.
