title: Combined microwave thermal ablation and liver resection for single step treatment of otherwise unresectable colorectal liver metastases; a monoistitutional experiences.
abstract: OBJECTIVE
  Over half of colorectal cancer patients will develop liver metastases.
  
  
  BACKGROUND
  Thermal ablation with or without associated liver resection for colorectal hepatic metastasis has been suggested as an alternative method to improve survival if radical surgical resection is not achievable. A retrospective case series of patients treated with microwave ablation(MWA) associated with hepatic resection in one step procedure, was reviewed to analyze the clinical outcome.
  
  
  METHODS
  In a group of 40 patients surgically cured for liver tumors in our Department, 5 patients with technically unresectable disease underwent combined treatment LR-MWA.
  
  
  RESULTS
  Four patients were treated with multiple segmentectomies and MWA and one patient received a left lobectomy (S2-S3) and MWA. Only 1 patient (20%) developed post surgical complication which was a liver abscess (grade II of Dindo classification).
  
  
  CONCLUSIONS
  Hepatic resection combined with MWA expanded indications for operative treatment of multiple bilobar liver metastasis. This procedure promise to have good long-term outcomes.
