Comparison of $LigaSure^{TM}$ and Bipolar Vessel Sealing System for Laparoscopic Ovariectomy in Cats

Abstract

The aim of this study was to investigate and compare technique, surgical time, and complications of laparoscopic ovariectomy using LigaSure TM and bipolar vessel sealing system in cats. Laparoscopic ovariectomy was performed under general anesthesia on 10 healthy female cats admitted for elective ovariectomy. Surgery was performed through three midline portals. Each ovary was randomly-assigned to removal by use of either LigaSure TM or bipolar vessel sealing system. Duration of predetermined surgery intervals and complications were compared. Bipolar OVE (2:16 ± 1:14 minutes) took significantly longer surgical time compared to the LigaSure TM OVE (1:24 ± 0:59 minutes, P = 0.021). The ovarian pedicle fat and obesity did not influence surgery duration. Intraoperative hemorrhage occurred with bipolar OVE in three cats, but had no significant influence on surgical time. The results suggest that both LigaSure TM and bipolar devices appear to be effective, but LigaSure TM can be used as a stand-alone device that decreases surgical time and complication compared with bipolar vessel sealing system.
