The patient was admitted to the hospital for 8 years with epigastric discomfort, aggravated in March. Intensive CT abdomen showed hypodense foci in the left lobe of the liver (bile duct occupancy is likely) and multiple gallbladder stones with cholecystitis. The patient had indications for surgery, but the scope of surgery was large and the technical requirements for laparoscopic surgery were high. After discussion in the department and active preoperative preparation, the F5C ward of general surgery decided to perform laparoscopic left hemicolectomy and cholecystectomy. Under the guidance of Prof. Hu Sanyuan and Prof. Zhang Zongli, the operation was performed by Associate Prof. Jin Bin, Attending Physician Du Gang, Attending Physician Liu Yanfeng and Dr. Li Jia. The gallbladder was firstly resected, then the hepatic round ligament and hepatic sickle ligament were dissected with ultrasonic knife, the first hepatic hilar was dissected, the branches of the left hepatic artery leading to segments II, III and IV of the liver were dissected, and they were respectively clamped and dissected with hem-o-lock clamps and absorbable clamps, and the The left branch of the portal vein was dissected and closed with absorbable clips, and the hemihepatic ischemic line was seen, attention was paid to protect the right hepatic artery, the right branch of the portal vein, and the common bile duct, then the second hepatic hilar was dissected to reveal the left hepatic vein, the left coronary ligament, the left delta ligament, and the hepatogastric ligament were dissected, and the pre-cut line was drawn with an electric knife about 1 cm to the left of the hemihepatic ischemic line, and the left hepatic surface and the liver tissue on the diaphragm were bluntly separated along the pre-cut line. -The large ducts were cut off by hem-lock clamps, and the left hemihepatic was resected by using cutting closures at the first and second hepatic hilum, and the hepatic trauma was cauterized by argon knife, and the subumbilical incision was extended to remove the specimen completely. The operation went smoothly, and postoperative dissection of the specimen showed multiple black stones in the gallbladder and dilated intrahepatic bile ducts in the left hepatic half with multiple black stones visible inside. The postoperative pathology showed (liver) cirrhosis with chronic inflammatory cell infiltration (predominantly lymphocytes) and dilated intrahepatic bile ducts with bile duct stones, and the patient got out of bed the first day after surgery and resumed eating early. Compared with traditional surgical methods, the longest incision of laparoscopic surgery is only about 6 cm (to extend the subumbilical incision to remove the specimen), which is less traumatic, with short exposure time of the abdominal cavity, good peritoneal integrity, fast recovery, less pain, shorter hospitalization and fewer complications. The patient recovers quickly, suffers less pain, has a shorter hospital stay, and has fewer complications. Of course, the technical requirements of laparoscopic surgery are high, requiring the surgeon not only to be proficient in the techniques of open surgery, but also to have good laparoscopic skills, and at present, laparoscopic hepatic left lobectomy and left hepatic partial resection are relatively widely carried out, and laparoscopic right hepatic partial resection is also further promoted, but hemihepatectomy is more difficult and relatively less carried out, and with the accumulation of experience and continuous improvement of surgical techniques, this type of surgery will become the most important procedure for surgeons. With the accumulation of experience and improvement of surgical techniques, this type of surgery will become the ideal surgical approach for doctors and patients.
