    Abstract:
    Perforated choledochal cysts is usually treated by open approach through a one- or two-stage procedure. Laparoscopic procedures are gradually being used more commonly with advancements in minimally invasive technology, while the level of difficulty and conversion rate are still high due to adhesions and deranged anatomy. Robot-assisted choledochal cyst excisions have been proposed as another minimally invasive procedure that is thought to improve operability and precision compared with laparoscopic surgery. However, there is still a lack about the use of robotic assistance for bilio-enteric reconstruction in pediatric patients with perforated choledochal cyst excisions. The aim of this current study was to investigate the safety and effectiveness of robotic-assisted procedures in pediatric perforated choledochal cyst excisions. Patients suffering from perforated choledochal cysts and treated with surgical procedures including open, laparoscopic, and robotic procedures between January 2009 and December 2021 were retrospectively analyzed. Robotic cyst excisions and hepaticojejunostomies were mainly used to a one-stage procedure (the pseudocyst formation or intra-mural perforation) or in stage 2 of two-stage procedures (complete perforation). Data collection included patient characteristics, intraoperative outcomes, and postoperative complications. There were a total of 64 patients suffering from perforated choledochal cysts were treated at our institution. Thirty-one cases of cyst excisions and hepaticojejunostomies were completed by open procedures. Twenty-two cases of cyst excisions and hepaticojejunostomies were completed by laparoscopic procedures and 11 cases were completed by robotic procedures. The operating times were significantly longer in the laparoscopic procedures group (214.32 ± 51.33 min) than found with either the open procedures group (130.55 ± 10.51 min) or the robot-assisted procedures group (188.82 ± 16.55 min) (p < 0.001). The time to oral intake, total complication, and hospital stay were similar among all three groups (3.53 ± 0.28 days vs 3.47 ± 0.30 days vs 3.46 ± 0.29 days, 19.35% vs 27.27% vs 18.18%, 11.48 ± 1.29 days vs 11.95 ± 2.75 days vs 11.55 ± 2.38 days, respectively) (p > 0.05). The number of biliary complications was higher in the laparoscopic procedures group (18.18%) than in both the open procedures and robot-assisted procedures groups (0.00%) (p = 0.016). Robotic-assisted cyst excision and hepaticojejunostomy procedures in patients with perforated choledochal cysts are both safe and feasible. What is more, they can achieve the same results as open procedures and also reduce the level of difficulty of operations and bring fewer biliary complications compared with laparoscopic procedures.
