Objective To explore the efficacy and risk factors of poor outcomes in children of pancreati-cobiliary maljunction without obvious biliary dilatation(PBM-nonOBD)after duodenoscopy.Methods From January 2020 to December 2022,retrospective analysis was conducted 1-on children with PBM-nonOBD treated by duodenoscopy in Children's Hospital of Fudan University.They were assigned into two groups of effective(n=24)and ineffective(n=20)treatment.Demographic profiles,clinical symptoms,laboratory tests and ima-ging studies were collected and the children were followed up.Univariate and multivariate Logistic regression ana-lyses were performed for identifying the risk factors influencing the outcomes after endoscopy.Receiver operating characteristic(ROC)curve was plotted for evaluate the predictive value of the relevant risk factors.Results During an average follow-up period of(19.7±8.6)months,the effective rate was 54.5％(24/44).Post-endo-scopic retrograde cholangiopancreatography pancreatitis was the most common postoperative adverse event(7/44,15.9％).Ultimately radical surgery(27.3％)and repeat endoscopy(15.9％)were required.No signifi-cant inter-group differences existed in such preoperative laboratory parameters as serum amylase,transaminases or bilirubin.B/D-type PBM subtype predominated in effective treatment group,accounting for 41.7％(10/24)and 37.5％(9/24)respectively.Univariate analysis indicated that younger age,longer common channel length and greater maximal diameter of common bile duct(CBD)were significant factors associated with poor out-comes after endoscopy(P＜0.05).Multivariable Logistic regression analysis revealed that younger age(OR=1.645,95％CI:1.645-2.309)and longer common channel length(OR=0.720,95％CI:0.720-0.968)were independent factors associated with poor outcomes(P＜0.05).Area under the ROC curve(AUC)was 0.838(95％CI:0.719～0.958)and 0.731(95％CI:0.567～0.894)and optimal cutoff values were 4.9 years and 8.8 mm respectively.Conclusions With minimal surgical trauma and no serious complications,duode-noscopy can effectively relieve symptoms in children of PBM-nonOBD.Young age and longer common channel length may be associated with poor postoperative outcomes after duodenoscopy.
