Abstract: A laparoscopic staged hepatectomy using round-the-liver ligation is carried out includes: (1) a laparoscopic operation is performed with general anesthesia using round-the-liver ligation, the branches of the portal vein of the hemiliver are ligated, a tourniquet is used to tighten the connecting part between the right and left hemilivers to block the communicating blood flow between the hemiliver to be removed and the hemiliver to be reserved, a drainage tube is put into the peritoneal cavity, then close the peritoneal cavity; (2) the patient gradually resumes eating after the first operation, and recuperate to make the volume of the hemiliver increase to an expected volume; (3) after the hemiliver increases to the expected volume, a laparoscopic liver resection is carried out with general anesthesia to remove the diseased hemiliver, and then the patient is nursed to be completely recovered. An instrument for implementing the laparoscopic staged hepatectomy is also disclosed.
