Identification of risk factors for intraoperative hemobilia and its correlation with early postoperative complications in patients with hepatolithiasis

BackgroundThis study intends to determine the risk factor(s) for intraoperative hemobilia in patients with hepatolithiasis and examine whether the occurrence of intraoperative hemobilia influences the rate of early postoperative complications.MethodsA retrospective analysis of 867 eligible patients was performed. Patients were divided into 2 groups: group A (hemobilia, n = 76) and group B (nonhemobilia, n = 791).ResultsThe incidence of intraoperative hemobilia was 8.8% (76/867). Independent risk factors of intraoperative hemobilia for patients with hepatolithiasis were interval between surgery and latest attack of acute cholangitis less than or equal to 38.8 days; preoperative attack of acute severe cholangitis; and intrahepatic duct stricture. Group A had a higher incidence of early postoperative complications than group B. Shorter interval between surgery and latest attack of acute cholangitis correlated with intraoperative hemobilia and postoperative complications.ConclusionThe severity and time of onset of preoperative acute cholangitis influence the risk of intraoperative hemobilia, which is positively correlated with early postoperative complications.
