Objective      To compare the advantages and disadvantages of cut-ultrasound aspiration (CUSA) combined with bipolar electric coagulation with radiofrequency coagulation in liver resection.       Methods      Clinical data of 108 patients who received liver resection in our hospital from January 2012 to December 2013 were collected and retrospectively analyzed. These patients were treated by CUSA combined with bipolar electric coagulation (CUSA group

n=53) or radiofrequency coagulation (RFA group

n=55). The portal vein blocking rate

operation time

intraoperative blood loss

blood transfusion rate

postoperative liver function

postoperative complications and postoperative hospitalization duration were compared between the 2 groups. The measured data were analyzed by student’s t test

and the enumeration data were analyzed by Chi-squan test.       Results      No patient died during the operation. The radiofrequency coagulation formed a melting solidification in 1.5 to 2 cm in liver resection

however

the thickness of liver tissue damage section  was about 0.5 cm by CUSA in liver resection.  The portal vein blocking rate

operation time

intraoperative blood loss

and blood transfusion rate of the RFA group were significantly lower than those of the CUSA group (P0.05). There were no differences in the postoperative liver function

postoperative complications and postoperative hospitalization duration between the 2 groups (P0.05).       Conclusion      Application of the radiofrequency coagulation and CUSA in liver resection is safe and effective. But each has its advantages and disadvantages.
