Cyst excision and Roux‑en‑Y hepaticojejunostomy (RYHJ) is the standard treatment for choledochal cysts (CCs). In the present study, the results of totally laparoscopic surgery for CCs (TLCCs) in a pediatric population were evaluated. The clinical data of 28 children with CCs between June 2020 and June 2023 were retrospectively reviewed. All patients underwent TLCCs involving cyst excision and RYHJ. The jejunojejunal anastomosis was completed laparoscopically using manual sutures. Age at operation, operative time, postoperative recovery and complications were evaluated. The 28 patients comprised 8 boys and 20 girls who underwent TLCCs at a mean age of 4.2 years (range, 1 month‑12.3 years) with a mean weight of 15.9 kg (range, 4.6‑43 kg). All patients received ultrasound and magnetic resonance cholangiopancreatography examinations, which revealed a mean cyst diameter and length of 1.74±0.76 cm and 3.85±1.25 cm, respectively. The mean operative time was 214±43.8 min. The mean time until starting an oral diet after surgery was 2.89±1.23 days. Apart from bile leakage and wound infection, no other complications occurred during a median follow‑up period of 18 months (range, 4‑42 months). TLCCs can be performed safely by skilled surgeons in pediatric patients. TLCCs may be more physiologically compatible and accelerate recovery of intestinal function with reduced trauma and better esthetic outcomes than conventional laparoscopic surgery for CCs. Therefore, TLCCs with manual sutures may be considered as an option for minimally invasive surgery in pediatric patients with CCs.
