Abstract

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. 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. 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). ILRFA is effective in achieving reducing blood loss and provides a drier operative field for precise dissection.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
