Evaluation of a vessel-sealing device for small intestinal resection and anastomosis in normal horses.
Abstract: To compare arterial bursting pressure after vessel closure using a vessel-sealing device (LigaSure Atlas Laparoscopic Sealer/Divider Instrument; Valleylab, Boulder, CO), a ligate-and-divide stapling device (LDS), and 2-0 polydioxanone suture. To evaluate the LigaSure Atlas as a method for ligation of the mesenteric vasculature during small intestinal resection in normal horses. Methods: Experimental study. Methods: Part A: jejunal segments from 19 horses. Part B: 6 horses, aged 1 to 18 years, weighing 330 to 509 kg. Methods: Part A: Jejunal segments with mesenteric vessels were collected from 19 horses. After closure by 1 of 3 methods (LigaSure Atlas, LDS, 2-0 polydioxanone) arteries were cannulated, and bursting pressure was measured by incrementally increasing intraluminal pressure until failure. Part B: Six horses had jejunal resection and anastomosis using a vessel-sealing device (LigaSure Atlas) to provide hemostasis of the mesenteric vasculature. Horses were monitored clinically for 4 weeks. Results: Part A: Mean +/- SEM bursting pressure after 2-0 polydioxanone ligation (1,014.50 +/- 279.05 mm Hg) was significantly greater than mean bursting pressure after LigaSure (554.25 +/- 228.79 mm Hg), which was significantly greater than the mean bursting pressure after LDS (373.25 +/- 183.69). Part B: No major operative or postoperative hemorrhage occurred after application of the LigaSure Atlas for sealing and transecting mesenteric vasculature during small intestinal resection in normal horses. Conclusions: The LigaSure Atlas appears to be a safe method for hemostasis of the mesenteric vasculature during small intestinal resection in normal horses. Conclusions: Benefits of the LigaSure Atlas vessel-sealing device include reduced time required to provide hemostasis, acceptable arterial bursting pressure, no remaining foreign material, and no risk for ligature slippage. In our experience, use of the LigaSure Atlas during small intestinal resection and anastomosis in horses is safe for ligation of vessels less than or equal to 7-mm diameter.

The research paper explores the comparison of three different techniques for closing blood vessels during small intestinal surgery in horses, aiming to determine the safety and effectiveness of a device known as the LigaSure Atlas.
Objective and Methodology
- The objective of the study was to compare the capacity of arterial vessels to withstand pressure after being closed using three different tools: the LigaSure Atlas, a ligate-and-divide stapling (LDS) device, and a 2-0 polydioxanone suture. This effect was measured using an arterial bursting pressure test. The researchers also wanted to evaluate the LigaSure Atlas as a technique for sealing blood vessels during small intestinal surgery in horses.
- The research study was divided into two parts: Part A involved jejunal (part of the small intestine) segments from 19 horses, and Part B involved six horses aged between 1 to 18 years. Each approach had a different focus, with Part A evaluating bursting pressures and Part B exploring jejunal resection and anastomosis (surgical connection of two separate parts) using the LigaSure Atlas.
Results
- The outcomes of the study were clear. The average bursting pressure after closure with a 2-0 polydioxanone suture was significantly higher compared to that after the LigaSure Atlas application. However, the pressure after LigaSure treatment was significantly greater than after the LDS method. Essentially, while the LigaSure Atlas did not yield the highest arterial pressure, it did perform better than the LDS device.
- In part B of the study, none of the horses experienced major operative or post-operative bleeding after the LigaSure Atlas was applied during small intestinal resection surgery. This outcome supported the LigaSure Atlas as a safe method for sealing blood vessels during such procedures.
Conclusion
- From the findings, the researchers confirm that the LigaSure Atlas is a safe and efficient device for stopping bleeding during small intestinal surgery in horses. It offers numerous benefits such as reduced surgical time, the absence of foreign materials post-surgery, and no risk of ligature slippage. The authors recommend the LigaSure Atlas for sealing vessels of up to 7mm diameter during small intestinal resection and anastomosis in horses.
