AIM: To assess the feasibility, safety and clinical value of laparoscopic anatomical segmental hepatectomy under the guidance of ultrasongraphy. METHODS: We performed laparoscopic liver resection in 20 patients from January 2005 to October 2006, including 13 cases of hepatocellular carcinoma, 1 case of cholangiocarcinoma, 3 cases of hemangioma, 1 case of adenoma, and 2 cases of liver abscess. All the cases received laparoscopic liver anatomy under endoscopic ultrasound guidance in complete pneumopertoneum. RESULTS: The mean operating time was 188 min, and the mean blood loss was 300 mL. There were no uncontrollable complications. The mean time of hospital stay after operation was 8.6 d. CONCLUSION: Segment-based hepatectomy under the guidance of ultrasonography conforms to the principle in tumor treatment and is worthy of being applied in liver surgery
