Objective:To explore the factors influencing the occurrence of postoperative cholangitis in children with congenital choledochal cysts,and to provide a theoretical basis for preventing the occurrence of postoperative cholangitis.Methods:A retrospective analysis was conducted on the clinical data of 127 children with congenital choledochal cysts who underwent laparoscopic surgery in our hospital from September 2020 to September 2022.Based on whether the postoperative cholangitis occurred,the patients were divided into the cholangitis group(n=21)and the non-cholangitis group(n=106).Clinical data were compared between the two groups to identify independent factors influencing the occurrence of postoperative cholangitis,and the predictive efficacy of these independent factors was evaluated using the receiver operating characteristic(ROC)curve.Results:Univariate analysis indicated that cyst diameter,anemia,the presence of biliary sludge and stones,and albumin levels on postoperative day 3 were associated with the occurrence of postoperative cholangitis in children with congenital choledochal cysts(P＜0.05).Multivariate analysis revealed that anemia and the presence of biliary sludge and stones were independent risk factors for postoperative cholangitis,while albumin levels on postoperative day 3 were an independent protective factor(P＜0.05).ROC curve analysis demonstrated that the three independent factors had predictive value for postoperative cholangitis,with areas under the curve(AUC)of 0.715,0.744,and 0.753,respectively.Conclusion:The occurrence of postoperative cholangitis in children with congenital choledochal cysts is closely related to anemia,the presence of biliary sludge and stones,and albumin levels on postoperative day 3.These factors have good predictive value for postoperative cholangitis and can guide targeted clinical interventions.
