From January the 1st 2022 to December the 31st 2022, 100 children aged under 18 years old had an appendicular peritonitis treated by laparoscopic appendectomy.~The pediatric surgeons either used the AirSeal System Valve-less Trocar or the standard insufflation.~On one hand, only the surgeon, the anesthetist and the nurses of the operating room knew which type of insufflation was used.~On the other hand, the patient, his parents and the nurses in the pediatric department did not know which type of insufflation was used.~The participants were divided in two groups: the Airseal group (A) and the standard group (S). In each group, the investigators studied and compared the postoperative pain, the consumption of analgesics, the operating time, and the length of stay for each participant.
The AirSeal System Valve-less Trocar is known to decrease postoperative pain, consumption of analgesics, operating time, and length of stay in adults during robotic and laparoscopic procedures.~The investigators would like to know if these allegations also apply to children.
