Objective To investigate the preventive measures for bleeding in laparoscopic hepatectomy. Methods The candidates for laparoscopic hepatectomy were 22 patients with live lesions， including 5 patients with primary liver cancer， 16 patients with liver hemangioma， and 1 patient with metastatic liver cancer. The tumors locatedthe left lateral lobe in 15 cases， caudate lobe in 1 case， segmentⅣin 2 cases， and segmentⅥ in 4 cases. The meandiameter of tumors was 4cm （2-10cm）. The surgical approaches included the left lateral lobectomy （15 cases）， leftlateral lobectomy of caudate （1 case）， and nonanatomic and wedge resection were performed in 6 cases. Results Twenty-two cases underwent laparoscopic liver resection， there were no conversion to open and operative death. The mean operative time was 115min （65-142min）， the mean blood loss was 450mL （270-780mL）， the mean length of hospital stay after operation was 6.5 days （3-11 days）. Conclusion Control liver section hemorrhage is a key technique in laparoscopic hepatectomy.
