Abstract:
Objective:To compare the clinical outcomes between the new cold-circulation bipolar radiofrequency assisted versus Habib-4X bipolar radiofrequency assisted open hemihepatectomy.Methods:A retrospective study was conducted on 45 patients who underwent bipolar radiofrequency assisted open hemihepatectomy at the Affiliated Tumor Hospital of Zhengzhou University from October 2016 to January 2020. There were 28 males and 17 females, with an average age of 52.2 years. These patients were divided into the experimental group ( n=20) who underwent the new cold-circulation bipolar radiofrequency assisted open liver resection, and the control group ( n=25) who underwent the Habib 4X bipolar radiofrequency assisted open liver resection. The postoperative alanine aminotransferase (ALT), postoperative aspartate aminotransferase (AST), liver coagulative necrosis plane width, speed of liver parenchymal transection, electrode needle carbonization rate, and postoperative complications were compared between groups. Results:In the experimental group, the speed of liver parenchymal transection was (5.0±2.0) cm 2/min, the width of the coagulative necrosis plane was (1.36±0.21) cm, the AST on the first postoperative day was (177.0±79.3) U/L, the ALT on the first postoperative day was (200.2±78.5) U/L, and the electrode needle tip carbonization rate was 20.0% (4/20). These figures were significantly better than the control group with (3.6±1.7) cm 2/min, (1.93±0.16) cm, (233.2±66.6) U/L, (249.2±62.9) U/L, and 56.0% (14/25), respectively (all P<0.05). The postoperative complication rate was 15.0% (3/20) in the experimental group and 24.0% (6/25) in the control group ( P>0.05). Conclusion:Cold-circulation bipolar radiofrequency assisted hemihepatectomy was safe and feasible. It had the advantages of rapid transection of liver parenchyma, a low electrode tip carbonization rate, and a more accurate coagulation range.
