Abstract    Objective    To study the clinical application and anatomical approach of controlling hepatic vein extraparenchymally before transection in laparoscopic hepatectomy. Methods    The clinical data of 15 patients performed controlling hepatic outflow extraparenchymally before transection in laparoscopic hepatectomy between May 2007 and April 2012 in Department of Minimally Invasive Surgery, First Affiliated Hospital of Guangxi Medical University were analyzed retrospectively. Results    Controlling hepatic vein extraparenchymally before transection was successfully finished in 15 patients. The operation included left lateral sectionectomy in 5 patients, left hepatectomy in 8 patients, right hepatectomy in 1 patient and hemangioma resection in 1 patient. Pre-parenchymal transection control of hepatic vein was performed in 15 patients, which included the left hepatic vein was controlled by suturing or separating in 13 patients and right hepatic vein was controlled by separating in 2 patients. The mean operative time was（261.0±79.5）mins. The mean blood loss during operation was（403.3±259.4）mL. Concentrated red blood cells transfusion volume was （1.1±2.0）U，and plasma transfusion volume was （66.7±144.8）mL. The mean hospitalization time was（14.0±3.1） days. The complications included postoperative bleeding in 1 patient and ascites in 1 patient. The follow-up ranged from 4 to 59 months. The recurrence was occurred during 3-14 months after operation. The recurrence rate was 54% and the survival rate was 57%.  Conclusion    Controlling hepatic vein extraparenchymally before transection in laparoscopic hepatectomy follows the anatomical approach, which is safe and reliable.
