Abstract
BackgroundFew reports have addressed postoperative infectious complications caused by multidrug-resistant pathogens. The aim of this study was to review the surgical outcomes of patients undergoing major hepatectomy with extrahepatic bile duct resection and to clarify the incidence of and the risk factors for postoperative infectious complications caused by multidrug-resistant pathogens. MethodsMedical records of consecutive patients who underwent major hepatectomy with extrahepatic bile duct resection between 2006 and 2017 were retrospectively reviewed. ResultsAmong 620 study patients, 219 had postoperative infectious complications, including 62 (10.0%) with postoperative infectious complications caused by multidrug-resistant pathogens. The mortality of the 62 patients with postoperative infectious complications caused by multidrug-resistant pathogens was higher (n = 8, 12.9%) than that in the 157 patients with postoperative infectious complications caused by non-multidrug-resistant pathogens(n = 2, 1.3%) (P < .001). With multivariate analysis, the presence of preoperative cholangitis, the extent of liver resection more than 50%, operative time longer than 600 minutes, the amount of blood loss more than 1500 mL, and the presence of postoperative infectious complications caused by multidrug-resistant pathogens were identified as independent risk factors for postoperative death. The presence of multidrug-resistant pathogens in preoperative bile culture, the amount of blood loss greater than 1500 mL, the presence of bile leakage, and pancreatic fistula were identified as independent risk factors for postoperative infectious complications caused by multidrug-resistant pathogens. ConclusionThe incidence of postoperative infectious complications caused by multidrug-resistant pathogens in patients undergoing major hepatectomy with extrahepatic bile duct resection is high, approximately 10%. This troublesome complication is closely associated with postoperative death. Thus, preventing postoperative infectious complications caused by multidrug-resistant pathogens is an urgent task to improve surgical outcome after major hepatectomy with extrahepatic bile duct resection.
