Choosing to enter the A or the S group depends on the surgeon's choice.~Only the surgeon, the anesthetic and the nurses in the operating room know which type of insufflation has been chosen.
The goal of this observational study is to compare the use of Airseal versus a standard insufflation, in children who underwent laparoscopic cholecystectomy, between January 2021 and December 2022.~The main questions it aims to answer are:~amount of analgesics consumed postoperatively~mean digital pain scale~Data are directly extracted from patients medical files.~The investigators will compare the Airseal group (A group) to the Standard insufflation group (S group) to see if the A group consumes significatively less analgesics and are less painful than the S group.
