title: [Effect of laparoscopic hepatectomy and microwave ablation for colorectal liver metastases].
abstract: OBJECTIVE
  To investigate the treatment effect of laparoscopic hepatectomy and microwave ablation for colorectal liver metastases.
  
  
  METHODS
  We retrospectively analyzed 126 patients who received treatment for colorectal liver metastases in our hospital during Jan. 2009 to Jan. 2015, and these patients were divided into laparoscopic surgical group (40 cases), microwave group (42 cases) and open surgical group (44 cases). The overall survival rate and disease-free survival rate were compared by using the Kaplan-Meier method.
  
  
  RESULTS
  The operation time in three groups were (120±35), (55±20), (100±30) min, respectively. The blood loss in the three groups were (300±120), (100±25), (250±95) ml, respectively. The operation time, blood loss and hospital stay in microwave group were less than the other two groups (P<0.05). There was no significant difference in survival time and postoperative complications in these groups (P>0.05).
  
  
  CONCLUSIONS
  Laparoscopic hepatectomy and microwave ablation in the treatment of colorectal liver metastases is effective compared to open hepatectomy. So the minimal invasive surgical techniques had benefit for patients with liver metastases from colorectal cancer.
