Intraoperative blood loss has been shown to be an important factor correlating with morbidity and mortality in liver surgery. A 5-cm long instrument with variably deployable metal electrodes using in-line radiofrequency ablation (ILRFA) energy was used for hepatic transection in an attempt to reduce bleeding.
Eight patients underwent liver resection. At each resection, half the resection was performed with ILRFA and the other half was performed with an ultrasonic aspirator alone. Blood loss was measured for each mode of resection.
The mean blood loss using ILRFA was 6.5 (+/-3.7) mL/cm(2) compared with 20.4 (+/-8.7) mL/cm(2) by using the ultrasonic aspirator (P = .004).
In-line radiofrequency ablation reduced bleeding during hepatic parenchymal transection when compared with the ultrasonic aspirator.
术中失血已被证明是肝手术中与发病率和死亡率相关的重要因素。一种使用在线射频消融（ILRFA）能量、带有可不同程度展开的金属电极的5厘米长器械被用于肝实质离断，以试图减少出血。
8例患者接受肝切除术。在每次切除术中，一半的切除使用ILRFA进行，另一半仅使用超声吸引器进行。测量每种切除方式的失血量。
使用ILRFA时的平均失血量为6.5（±3.7）mL/cm²，而使用超声吸引器时为20.4（±8.7）mL/cm²（P = 0.004）。
与超声吸引器相比，在线射频消融减少了肝实质离断过程中的出血。
