Popis: | [EN] Materials and Methods: We performed a comparative experimental study between a new radiofrequency (RF)-assisted device consisting of a handheld instrument that simultaneously conducts coagulation and cutting tasks without hilar clamping vs a standard technique with hilar clamping. A porcine model was used (10 animals per group) with survival of 17 days. Results: The estimated blood loss with the new device was significantly lower than with the standard technique (15.5 +/- 23.7 vs 79.4 +/- 76.3 mL). Although transection time was longer with the new device (10.7 +/- 13.7 vs 2.1 +/- 1.2 min), the total operative time was significantly shorter (35.3 +/- 13.7 vs 60.2 +/- 10.5 min). Evidence of localized urinary extravasation (urinoma) was identical in both groups (five cases). The group subjected to the new device, however, showed a significantly higher number of cases of leakage after conducting the methylene-blue test: eight (80%) cases vs only one (11%) with the standard technique. Necrosis depth was significantly greater with the new device (6.6 +/- 0.9 vs This work received financial support from the Spanish "Plan Nacional de I + D + I del Ministerio de Ciencia e Innovacion," Grant No. TEC2008-01369/TEC.
