The widely used conventional laparoscopy requires the conversion of two-dimensional images in the monitor into three-dimensional images, which leads to a long learning curve, especially for complex surgeries. The da Vinci robotic surgical system has been successfully used in adult general surgery, urology, cardiothoracic surgery, obstetrics and gynecology, and pediatric surgery at home and abroad because of its precise three-dimensional images, manual-like operation, and short learning curve for complex procedures.] However, the expensive acquisition and use of the da Vinci robotic surgical system has forced attempts to use the 3D imaging portion of the system in part for its assisted surgery. From June 2013 to April 2014, we have data on 52 surgical procedures performed with Viking’s 3D laparoscopic system, 30 males and 22 females, aged 6 months to 14 years, with an average age of 4 years and 8 months, divided into three groups of “high, medium, and low” according to the difficulty of the procedure. The high difficulty group included: common bile duct cyst (6 cases), congenital megacolon and homologous disease (10 cases, including 3 cases with subtotal radical surgery), portal hypertension with hypersplenism (1 case), and esophageal hiatal hernia (1 case due to intraoperative esophageal perforation, so it was classified as such). Medium difficulty group: cholecystitis combined with gallbladder stones (1 case), acute appendicitis (2 cases of purulent appendicitis, 3 cases of gangrenous perforated appendicitis, 3 cases of periappendiceal abscess), and intestinal duplication malformation (1 case). In the low difficulty group: inguinal hernia unilateral/bilateral (12 cases/5 cases), unilateral and bilateral cryptorchidism (3 cases/4 cases), in the high difficulty group, children with choledochal cysts were completed successfully; congenital megacolon and homologous disease were completed successfully, 3 cases of subtotal radical surgery were completed, and a total of 3 cases of congenital megacolon heart-shaped anastomosis were completed by simple transumbilical approach, among which 2 cases of left hemicolectomy took an average of 135 minutes. In one case, the time for subtotal colectomy was 180 minutes; in the other case, the hypersplenism in combination with portal hypertension was opened because the spleen was huge and it was difficult to reveal the splenic hilum, and in the other case, the esophagus was perforated when the ultrasonic knife was used to free the esophagus during hiatal hernia surgery. In the first case of acute appendicitis, due to severe adhesions, unclear anatomy and close spacing of trocar, the surgery was completed by adding trocar to the left lower abdomen, and the rest were done by simple transumbilical laparoscopy. The lesion was removed and intestinal anastomosis was performed outside the abdominal cavity. All inguinal hernia and cryptorchidism were successfully completed in the low difficulty surgery. All children recovered well after surgery, and all children were discharged from the hospital with regular outpatient follow-up and telephone follow-up for 1 to 11 months, with no long-term complications. After our use, we believe that 3D laparoscopy can reduce the difficulty of surgery, shorten the operation time, be suitable for fine anastomosis, shorten the learning curve, and can be widely used in pediatric surgery.
