BACKGROUND: The ForceTriad™ generator has been recently developed. This new electrosurgical generator would demonstrate improved quality and efficiency in blood vessel sealing. AIM: To compare currently available 10-mm laparoscopic electrosurgical devices with the LigaSure™ Vessel Sealing System and ForceTriad generator (Valleylab, Inc., a division of Tyco Healthcare) for use in vessel sealing. METHODS: Blood vessels of various types and diameters were harvested from alive four pigs using three instruments: LigaSure Atlas™ with LigaSure Vessel Sealing Generator (LSAt), LigaSure Atlas with ForceTriad Generator (LSAtFT), and Endoclip™ II (Autosuture, USSC; a division of Tyco Healthcare). A total of 100 arteries were processed by removal of fatty and connective tissue from the adventitia before sealing. An additional set of specimens was sealed and histopathologically analyzed after being stained with hematoxylin and eosin. RESULTS: The mean burst pressure was significantly higher with LSAtFT compared to LSAt (P < 0.01). The sealing process was significantly shorter with LSAtFT (P < 0.05). With regard to the degree of thermal injury, adventitial collagen denaturation and proximal thermal injury to the smooth muscle in the media of the vessel wall were less common with LSAtFT; however, the numbers were too small for statistical analysis. CONCLUSION: Both the LSAt and LSAtFT secured all vessel sizes to well above physiologic levels. The LSAtFT could be used more confidently in vessels up to 7 mm. Our findings indicate that LSAtFT could be a safer and more efficient instrument for advanced laparoscopic surgery. |
