Abstract

The objectives of this study were to compare (1) the extent of thermal damage and (2) the time between the 5-mm LigaSure V (LS5) and 10-mm LigaSure Atlas (LS10) vessel sealing devices (VSD) when performing open ovariectomy in dogs. A prospective, randomised, clinical trial was performed in 40 client-owned sexually entire female dogs. In each dog, one ovary was randomly assigned to be surgically removed using LS5 and the contralateral using LS10. The depth of thermal spread, measured on histopathological preparations, was significantly larger for LS10 (LS10 1.35 +/- 0.23 mm v LS5 0.82 +/- 0.10 mm; P<0.001). Mean ovariectomy time was significantly faster when using LS10 (LS5 2.58 +/- 1.32 minutes v LS10 2.07 +/- 1.27 minutes; P=0.008). Bodywe...
