Risk Factors for Anastomotic Stenosis After Congenital Choledochal Cyst Surgery and Efficacy Analysis of Laparoscopic Reoperation

Abstract

Congenital choledochal cyst (CCC) is a common congenital biliary dysplasia in children, with higher incidence in Asia, treated by complete cyst excision plus Roux-en-Y hepaticojejunostomy (laparoscopy as preferred). Anastomotic stenosis, a common long-term postoperative complication, increases patient burden and treatment difficulty. Previous studies lacked systematic analysis of its influencing factors, and laparoscopic reoperation for it was once contraindicated, with only small-scale studies showing its efficacy comparable to open surgery.
