title: Laparoscopic hepatectomy is associated with considerably less morbidity and a long-term survival similar to that of the open procedure in patients with hepatic colorectal metastases.
abstract: BACKGROUND
  Laparoscopic hepatectomy (LH) provides significant promising results when compared with open hepatectomy (OH). However, the oncologic outcome of LH for hepatic colorectal metastases (HCRM) remains controversial. The purpose of this study was to review the results of LH retrospectively and to compare them with those obtained using the conventional OH procedure for HCRM patients.
  
  
  METHODS
  Demographic details of 24 patients with pathologic determination of HCRM who underwent LH were reviewed retrospectively and weighed against the 25 HCRM patients chosen from the prospective OH database. Postsurgical benefits and 3-year outcomes of these 2 groups were compared.
  
  
  RESULTS
  The LH had a significantly less estimated blood loss (210 vs. 380 mL; P<0.01), less analgesic requirements (20.8% vs. 50.2%; P<0.001), shorter hospital stay (7.4 vs. 11.4 d; P<0.0001), and less postoperative complication rates (25% vs. 48%; P=0.02) compared with the OH approach. The operative time, positive surgical margin, and postoperative liver function changes were similar in the 2 groups. There were no significant differences between the 2 groups in tumor recurrence and the 3-year overall survival rate (24% vs. 30%; P=0.83), respectively.
  
  
  CONCLUSIONS
  LH is a practicable replacement for OH with probable advantages within the short-term outcomes for elected HCRM patients. Nevertheless, it remains an approach in advancement; in addition, randomized controlled trails and prolonged follow-up are necessary to verify its oncologic benefits and long-term survival.
