Laparoscopic ovariectomy in cats: Comparison of laser and bipolar electrocoagulation (THESIS VERSION)

Abstract

Fourteen mixed-breed domestic cats underwent laparoscopic ovariectomy (lapOVE) using pediatric equipment, a Nd:YAG laser and a bipolar electrocoagulation forceps. Cats were placed in 10o Trendelenburg position (head down) and insufflation pressure was kept at 4 mmHg, while surgery was performed through three midline portals. Randomly-assigned unilateral laser resection of one ovary (Laser-OVE) and bipolar electrocoagulation (BEC-OVE) of the contralateral ovary were performed. Duration of predetermined surgery intervals were recorded, as well as occurrence of intra- and post-operative complications. Both methods were successful and without complications. Duration of Laser-OVE was significantly increased compared to BEC-OVE. The right ovary was more difficult to access; however, both ovaries were easy to manipulate because of the relatively long suspensory ligament. The ovarian ligaments contained minimal amounts of fat and obesity did not influence surgery duration. Convalescence period was short (0.9 ± 0.4 days) and owner satisfaction high.
