The incidence of bile duct invasion, vascular invasion, extrahepatic involvement and other organs were 2.5%, 18.75%, 26.25% and 11.25%, respectively. The average operative time was 343 min, the average intraoperative blood loss was 390 ml, the average drainage time was 7.9 d, and the average hospital stay was 27.5 d. The recurrence rate of complications was 21.25%, mainly fat liquefaction (14 cases) and bile leakage (3 cases), which were properly treated in the later stage.
