Laparoscopic cholecystectomy is a new technique based on endoscopy, which is a “hole-cutting” operation. A small 1 cm long skin incision (A-hole) is made next to the navel, then a pneumoperitoneum needle is inserted into the abdominal cavity through this incision and carbon dioxide gas is injected into the abdominal cavity, causing a pneumoperitoneum to bulge the abdominal cavity, a 1 cm needle is inserted through this skin incision, a laparoscope is inserted, and a TV camera system is connected to the endoscope so that the operator can observe the situation in the abdominal cavity through the monitor fluorescent screen. If it is determined that cholecystectomy is feasible, then the second and third holes (holes B and C) are made under the fenestra of the sword (at the heart fossa) and under the right rib margin, special surgical instruments are placed, and the surgical operation of separation and removal of the gallbladder is performed by observing the TV fluorescent screen, and finally the gallbladder is removed by the second small hole after removal. Laparoscopic cholecystectomy is a minimally invasive surgery that has been widely used in the treatment of gallbladder stones and gallbladder polyps. This surgery has obvious advantages such as less trauma, less pain, quicker recovery, no obvious surgical scars and safe and reliable. The whole operation takes about 30~60 minutes and the recovery after the surgery is fast, usually 3~4 days before discharge.
