Laparoscopic cholecystectomy is a common procedure in biliary surgery. Traditional open cholecystectomy is poorly targeted, traumatic, slow to heal, and prone to complications, resulting in significant patient pain and poor postoperative recovery. Since the development of laparoscopic cholecystectomy, this procedure has rapidly gained acceptance among surgeons and patients. The main operation steps of laparoscopic cholecystectomy: 1. Establish the operation hole: make a 1 mm transverse incision 1 cm below the glabella and insert a 10 mm trocar needle as the main operation hole, from which the electrocoagulation hook is inserted. A 5-mm incision was made in the midclavicular line, 1 cm below the rib margin, from which a 5-mm trocar needle was inserted, and this channel was used as the operating hole for gallbladder grasping forceps. A 5-mm incision is made in the anterior axillary line, under the rib margin, from which a 5-mm trocar needle is inserted, and this channel is the auxiliary operating hole through which the first assistant can assist in exposing the surgical field. 2. Treatment of the gallbladder triangle: If there are adhesions between the gallbladder and the intra-abdominal organs, a sponge rod can be used for blunt separation. After being able to distinguish the common bile duct, common hepatic duct, and cystic duct, the plasma muscle layer is carefully incised at the gallbladder jugular with an electrocoagulation hook. From there, a blunt separation is made in the direction of the common bile duct to fully expose the common bile duct, common cystic duct, and common hepatic duct. After confirming the above anatomical relationships, the tissues surrounding the common bile duct are separated, and care should be taken not to burn the common bile duct at this time. The cystic duct is closed with a titanium clamp 3-5 mm from the common bile duct and cut off. After the gallbladder artery is revealed correctly, the gallbladder artery is cut off by clamping. 3, peel the gallbladder: lift the neck of the gallbladder, and gradually cut the gallbladder from the gallbladder bed about 5 mm from the liver. The oozing blood on the gallbladder bed was treated with adequate electrocoagulation. After careful exploration to confirm that there is no active bleeding in the abdominal cavity, no damage to the bile duct and other organs in the abdominal cavity, the gallbladder is placed in the specimen bag, and then the laparoscope is moved to the subxiphoid process and the gallbladder is removed from the body through the umbilical incision. 4. CO2 is released and the pneumoperitoneum is eliminated. The umbilical and subxiphoid incisions need to be sutured to the anterior rectus abdominis sheath, and the wounds are closed with Band-Aids. Precautions for laparoscopic cholecystectomy In the process of laparoscopic cholecystectomy, if the following conditions are found, the continued use of laparoscopic cholecystectomy is likely to produce complications such as bile duct injury, and should be transferred to open surgery according to the specific situation. In addition, if intraoperative vascular injury has been found to cause active bleeding, bile duct injury, electrical burns to the bile duct wall, and organ injuries such as duodenal injury should also be promptly referred for open surgery in order to deal with these injuries.
