Abstract

Background: Untreated pediatric choledochal cyst (CC) is associated with complications including cholangitis, pancreatitis, and risk of malignancy. Therefore, CC is typically treated by surgical excision with biliary reconstruction. Both open and laparoscopic (lap) surgical approaches are regularly used, but outcomes have not been compared on a national level.

Methods: The Nationwide Readmissions Database was used to identify pediatric patients (age 0-21 years, excluding newborns) with choledochal cyst from 2016 to 2018 based on ICD-10 codes. Patients were stratified by operative approach (open vs. lap). Demographics, operative management, and complications were compared using standard statistical tests. Results were weighted for national estimates.

Results: Choledochal cyst excision was performed in 577 children (75% female) via lap (28%) and open (72%) surgical approaches. Patients undergoing an open resection experienced longer index hospital length of stay (LOS), higher total cost, and more complications. Anastomotic technique differed by approach, with Roux-en-Y hepaticojejunostomy (RYHJ) more often utilized with open cases (86% vs. 29%) and hepaticoduodenostomy (HD) more common with laparoscopic procedures (71% vs. 15%), both p < 0.001. There was no significant difference in post-operative cholangitis or mortality.

Conclusions: Although utilized less frequently than an open approach, laparoscopic choledochal cyst resection is safe in pediatric patients and is associated with shorter LOS, lower costs, and fewer complications. HD anastomosis is more commonly performed during laparoscopic procedures, whereas RYHJ more commonly used with the open approach. While HD is associated with more short-term gastrointestinal dysfunction than RYHJ, the latter is more commonly associated with sepsis, wound infection, and respiratory dysfunction.

Level of evidence: Level III: Retrospective Comparative Study.
