Patient female, 42 years old, was admitted to the hospital due to the discovery of hepatic occupations for more than 3 months, abdominal intensive CT showed multiple occupations in the liver, and hemangioma was considered, the patient had 2 hemangiomas in the right liver with a diameter of more than 10 cm, which was a huge hemangioma in the liver, and the patient had surgical indications, and the general surgery department, F5C ward, after the discussion of the department, decided to perform laparoscopic right hemihepatectomy. Exploration: 2 hemangiomas were seen in the right half of the liver, each about 12×10cm and 10×10cm, and one of them was partially located in segment IV of the liver. Firstly, the gallbladder was resected, then the first hepatic portal was dissected, and the branches of the right hepatic artery leading to the right anterior and right posterior lobes of the liver were dissected out, and they were isolated after being clamped off by upper hem-o-lock clips, and the right branch of the portal vein was dissected out, and was clamped off by hem-o-lock clips, and then the hemi-lateral ischemic line was seen to appear, and a blockage band was pre-positioned in the first portal, and the second portal was isolated, and the right hepatic vein was exposed, and the third portal was isolated. The short hepatic vessels were dissected out, and the hem-o-lock was clamped and severed, then a pre-cut line was drawn along the right side of the hemi-hepatic ischemic line about 1 cm and the left side of the hemangioma (segment IV of the liver) about 1 cm, and the hepatic tissues were dissected along the pre-cut line, and the large ducts were clamped with the hem-o-lock and severed, and the first hepatic hilar was blocked when the liver was dissected from segment IV of the liver, and the first two hepatic hilar were dissected with the use of a cutting occluder. The first hepatic hilar was dissected, and the hepatic hemangioma and liver tissue were resected together. The blocking time was about 20 minutes, and the right half of the liver and the gallbladder were put into the retrieval device, and then the abdominal incision was removed, and the specimen was taken out completely, and the incisions were closed with sutures. The operation went smoothly and the patient returned to the ward peacefully after the operation. Postoperative pathology showed cavernous hemangioma (liver). The gastric tube was removed on the first postoperative day, and the patient was given a liquid diet and got out of bed, and he recovered well and was discharged from the hospital. Characteristics of this case: the operation was completed completely under laparoscopy, and there were only several incisions of about 0.5-1cm in length in the upper abdomen, which was less traumatic, with shorter exposure time of the abdominal cavity, better integrity of the peritoneum, faster recovery and less pain for the patient; half-hepatic hemoblock was used first, and then the first hepatic portal block was used for the resection of angiomas that were more than the half-hepatic line, which reduced the time of first-hepatic portal block, and decreased ischemia/reperfusion injury to the liver, which was conducive to the recovery of liver function after operation; the removal of the hepatic cavernous hemangioma was performed with a gastric tube. The incision for removing the specimen was located in the lower abdomen above the pubic symphysis, and the patient could easily cover the incision with underwear, which was favorable to the cosmetic effect. Due to the anatomical location and characteristics of the right hemihepatic, laparoscopic right hemihepatectomy is difficult and risky. At present, laparoscopic hepatic left lobectomy and left partial hepatectomy are relatively widely carried out, and laparoscopic right hemihepatectomy is further promoted, but hemihepatectomy is more difficult to carry out, and is carried out relatively less. With the accumulation of years of experience, on the basis of laparoscopic left external lobectomy of the liver, resection of all segments of the left liver, resection of all segments of the right liver, and left hemihepatectomy, the first laparoscopic right hemihepatectomy was carried out in the hospital in F5C ward of the Department of General Surgery.
