目的：探讨射频凝血器在肝切除术中临床疗效和应用价值。 方法：回顾性分析2011年7月—2013年7月行肝切除手术108例患者的临床资料，其中41例行射频凝血器断肝（观察组），67例应用传统钳夹法断肝（对照组），比较两组的临床效果。 结果：与对照组比较，观察组手术时间、术中出血量、输血患者比例及肝门阻断比例均少于对照组；术后转氨酶和胆红素上升数值、腹腔引流量及住院时间均低于对照组，差异均有统计学意义（均P0.05）。 结论：应用射频凝血器可有效减少出血，降低对肝脏损害，缩短住院时间，且不明显增加住院费用，在肝切除中有应用价值。“,”Objective:To investigate the clinical efficacy and value of using radiofrequency coagulation device in liver resection. Methods:The clinical data of 108 patients undergoing hepatectomy from July 2011 to July 2013 were retrospective analyzed. Of the patients, 41 cases underwent radiofrequency-assisted liver transection (observational group), and 67 cases underwent liver transection using conventional clamp technique (control group). hTe clinical variables between the two groups were compared. Results: In observational group compared with control group, the operative time, intraoperative blood loss, and the percentage of cases requiring blood transfusion and hepatic portal occlusion were reduced, the values of postoperative transaminase and bilirubin were decreased, the volume of postoperative peritoneal drainage and length of hospital stay were decreased, and all the differences reached statistical signiifcance (all P0.05). Conclusion:The use of radiofrequency coagulation in liver resection can effectively control blood loss and decrease liver damage and length of hospital stay, and does not increase medical expenses, so it can valuably be applied in hepatectomy.
