”Minimally invasive surgery is one of the advantages of minimally invasive surgery, such as less damage, aesthetics, and faster recovery of the child after surgery. Minimally invasive laparoscopic surgery was gradually carried out in the field of pediatric surgery in the late 1990s, and after 2000 minimally invasive laparoscopic surgery became gradually popular in pediatric surgery. At present, laparoscopic minimally invasive surgery in pediatric surgery has become a worldwide trend. 90% of the surgeries in our hospital are performed through laparoscopic minimally invasive surgery every year. The reason why laparoscopic minimally invasive surgery is so widely used is not only because of the minimal damage, aesthetic appearance and fast postoperative recovery, but also because the most crucial reason is that laparoscopic minimally invasive surgery achieves or even exceeds the therapeutic effect of open surgery. In the case of choledochal cyst surgery, ordinary open surgery, because the postoperative field of view is obscured by the liver and intestinal ducts, and the surgical operation is performed in the deep position of the hepatic portal, it is often difficult to expose clearly, and the operator’s field of view is greatly restricted during the operation, which is often unfavorable, especially when performing hepatic duct jejunostomy, the most critical anastomosis site, which is extremely difficult to expose. Such problems are solved in laparotomy, where the laparoscope can flexibly and deeply probe the hepatoportal area, while the laparoscope has the function of magnification four times, so that it is very fine when separating the cyst and anastomosis anastomosis, achieving precise and detailed results, and the surgical results are naturally guaranteed. Also some blood vessels that are difficult to identify with the naked eye can be easily seen and treated in a timely manner, greatly reducing the amount of bleeding. The advantages of minimally invasive laparoscopic surgery are good surgical results, minimal trauma, beautiful abdominal wall, and fast postoperative recovery.
