Clinical Application Value of Modified Laparoscopic Radical Resection for Congenital Choledochal Cyst

Objective : To evaluate the clinical efficacy of the modified laparoscopic radical resection of congenital choledochal cysts. Methods : A retrospective analysis was conducted on 33 pediatric patients with congenital choledochal cysts treated at our institution from September 2018 to December 2024. The control group (n=18) underwent traditional laparoscopic surgery (September 2018–December 2021), while the modified group (n=15) received the modified technique (January 2022–December 2024). Baseline characteristics (gender, age, weight, preoperative laboratory tests) and perioperative outcomes (intraoperative blood loss, postoperative drainage volume, tube indwelling time, time to initiate feeding, hospital stay, costs, and complications) were compared between the two groups. Results : No significant differences were observed in baseline characteristics (age, gender, weight) or preoperative laboratory parameters (white blood cell count, hemoglobin, prealbumin, retinol-binding protein, liver enzymes, conjugated bilirubin, etc.) between the two groups (P > 0.05). There was no statistically significant difference in postoperative complications (fever, vomiting, abdominal distension, anastomotic leakage, anastomotic stenosis, bleeding, intra-abdominal infection, cholangitis, pancreatic fistula, and wound infection) between the two groups (P > 0.05).The modified group showed significantly reduced postoperative drainage volume, shorter abdominal drainage/gastric tube indwelling time, earlier feeding initiation, shorter hospital stays, and lower costs (P <0.05). Conclusion : Modified laparoscopic radical resection for congenital choledochal cysts reduces postoperative exudate, accelerates recovery, lowers hospitalization costs, demonstrating clinical safety and efficacy.
