Abstract:

The operation is mainly divided into three parts: Laparoscopic hepatoduodenal ligament lymph node dissection, laparoscopic right hemihepatectomy and laparoscopic cholangiojejunostomy. After anesthesia, the patient took the supine position, "lifting method" to establish pneumoperitoneum, and trocar and operating instruments were placed using five hole method. Firstly, dissect and skeletonize the hepatoduodenal ligament, expose the internal blood vessels and bile duct branches, cut off the common bile duct at the upper edge of the duodenum, and remove the gallbladder at the same time. Then, the right half of the liver was fully dissociated. After dissecting the free left hepatic duct, it was cut off at 1cm above the tumor, the right branch of the portal vein was cut off, and the right half of the liver and the right part of the caudate lobe were removed along the hemihepatic ischemia line. Finally, the jejunum was lifted up to the left hepatic duct, after biliary-enteric anastomosis and intestinal anastomosis, the incision was prolonged, and the specimen was taken out of the bag.
