Patient’s condition: The patient, female, 29 years old, was found to have a giant hepatic tumor for more than 2 years, with progressive enlargement. MRI suggested a giant left hepatic occupancy, immediately adjacent to the middle hepatic vein and inferior vena cava, preoperative diagnosis: giant left hepatic FNH. The tumor was completely resected without intraoperative blood transfusion and was discharged on the 5th postoperative day.

This patient’s tumor was huge and close to the large blood vessels, which was difficult even with traditional open surgery, and the worldwide expert consensus also considered that huge liver tumors close to large blood vessels were not suitable for laparoscopic surgery. The patient himself strongly requested laparoscopic surgery, and after full communication and understanding the possibility of open surgery, he decided to operate. The laparoscopic ultrasound positioning, careful dissection and skillful operation made such an extremely difficult laparoscopic liver surgery end perfectly.
