%X Although bile leakage is a major postoperative complication after hepatobiliary surgery, the associated risk factors for pediatric patients remain poorly defined. Here, we intend to identify the perioperative risk factors for bile leakage in pediatric patients with choledochal cysts following Roux-en-Y hepaticojejunostomy. A multicenter case-control study investigating the risk factors for bile leakage was conducted among 1179 eligible pediatric patients with choledochal cysts following Roux-en-Y hepaticojejunostomy between January 2009 and December 2019. There were 267 cases with bile leakage, and approximately four control patients were identified for each case. Multivariable logistic regression was performed to identify the risk factors, including perioperative variables. According to univariable analysis, bile leakage was associated with severe cholangitis (p = 0.012), low albumin levels (p = 0.010), anemia (p = 0.002) and laparoscopic surgery (p = 0.004). Multivariable analysis showed that a low level of preoperative albumin (ALB) (odds ratio [OR] = 1.11; 95% CI 1.02-1.19; p = 0.016), worse symptoms (severe cholangitis) (OR = 1.16; 95% CI 1.01-1.26; p < 0.001), and a previous hepatobiliary procedure (OR = 1.32; 95% CI 1.09-1.63; p = 0.036) were independent factors that were associated with bile leakage. This study identified potential risk factors for bile leakage in patients following Roux-en-Y hepaticojejunostomy that should be targeted for interventions to reduce the occurrence of the condition.
