BACKGROUND
Bipolar inline radiofrequency ablation (ILRFA) is an effective way to control bleeding during parenchymal organ transection. This was investigated in a study of laparoscopic hand-assisted partial nephrectomy in swine.
METHODS
Nine Landrace pigs were divided between 2 groups; diathermy was employed in the control group for parenchymal transaction and ILRFA was applied in the experimental group through a hand-port and deployed into the resection plane. After complete coagulation, resection was performed using scissors.
RESULTS
The mean intraoperative blood loss was 32 +/- 15 mL in the ILRFA group and 187 +/- 69 mL in the control group: a 82.9% reduction ( P = .015). The mean blood loss per resection area was 2.53 +/- 0.92 mL/cm(2) in the ILRFA group compared with 17.31 +/- 9.05 mL/cm( 2) in controls; the reduction was 85.4% (P = .005).
CONCLUSIONS
ILRFA is effective in achieving reducing blood loss and provides a drier operative field for precise dissection.
背景
双极线性射频消融术（ILRFA）是控制实质性器官横断时出血的一种有效方法。在一项猪腹腔镜手辅助部分肾切除术的研究中对此进行了调查。
方法
将9头长白猪分为2组；对照组采用透热法进行实质组织处理，实验组通过手辅助端口应用ILRFA并将其置于切除平面。完全凝固后，用剪刀进行切除。
结果
ILRFA组术中平均失血量为32±15 mL，对照组为187±69 mL：减少了82.9%（P = 0.015）。ILRFA组每切除面积的平均失血量为2.53±0.92 mL/cm²，而对照组为17.31±9.05 mL/cm²；减少了85.4%（P = 0.005）。
结论
ILRFA在减少失血方面有效，并为精确解剖提供了更干燥的手术视野。
