Traditional cesarean cholecystectomy is performed by cutting open the abdominal wall and then operating directly under the naked eye, with the incision generally being 15-20 cm, and the surgeon entering the abdominal cavity with instruments in hand to perform various operations. However, laparoscopic cholecystectomy, as the name implies, the surgeon does not observe the abdominal cavity with the naked eye, but operates through a 1cm thick laparoscope by transferring the image to a TV screen and watching the TV screen, so that the surgeon only needs to make 1-3 small holes (usually 0.3-1cm) in the abdominal wall, insert the specially designed minimally invasive instruments, watch the screen operation to cut down the gallbladder, and then operate from the abdominal wall to remove the gallbladder. The excised gallbladder is then removed from the abdominal wall along with the stones through the small holes. This operation is also called TV laparoscopic surgery, commonly known as “small-hole cholecystectomy”.
