Letter to the Editor Comment on: Development and validation of a predictive model for bile leakage after choledochal cyst excision in children: A multicenter retrospective cohort study

Abstract

I read with interest the recent multicenter study by Ding et al.[1], which develops and externally validates a nomogram for predicting postoperative bile leakage in children undergoing choledochal cyst excision. The rigorous methodology—combining LASSO regression, bootstrap internal validation, and an independent external cohort—offers a meaningful contribution to perioperative risk stratification in pediatric biliary surgery. Several points, however, merit further discussion.
