Comparison of Two Radiofrequency Vessel-Sealing Device for Laparoscopic Ovariectomy in African Lionesses (Panthera Leo)

Abstract

To evaluate two vessel-sealing devices with different jaw lengths for dissecting ovaries in adult obese African lionesses undergoing laparoscopic ovariectomy. Twelve lionesses (n = 12) were recruited. The surgical procedures were performed through three portals, with a retractor platform positioned at the umbilical port and cannulas placed 3–4 cm cranial and caudal to the device at the level of the midline. Ovariectomy was performed using a vessel-sealing device according to a randomization list. We evaluated the surgery time the intra- and postoperative complications. The total surgery time was 49.3 min (range 40–61 min) in the Atlas group and significantly lower in the Caiman group (mean 31.8 min, range 26–51 min). The installation phase was similar between the groups. The ovariectomy time was significantly lower in the Caiman group (mean 7.8 min, range 4–11 min) than in the Atlas group (mean 20 min, range 16–30 min). Controlled bleeding was observed at the tip of the uterine horn in two cases in the Atlas group. No other complications were noted. The results of our study confirmed the significant advantages of employing the Caiman 12 vessel-sealing device in comparison with the LigaSure Atlas in terms of the time needed to complete ovariectomy, although both instruments could be considered safe. The use of the Caiman 12 is recommended when performing laparoscopic ovariectomies in adults with obesity.

“…Moreover, the use of vascular dissection and coagulation device allows a reduction in surgical time and safety in tissues bleeding control as reported by Lacitignola et al 2022 andCicirelli et al 2023. In this study, in both groups, Caiman® (Aesculap -Tuttlingen) was used to perform the surgeries and there were no intra-or post-operative complications.…”

Ovariectomy in mouflons under field conditions: a comparative assessment of midventral and flank laparotomy approaches

“…The disadvantage of ventral laparotomy is related to the risk of evisceration in the event of surgical wound dehiscence ( 5 ). Moreover, the use of vascular dissection and coagulation devices allows a reduction in the surgical time and safety in tissue bleeding, as reported by Cicirelli et al ( 18 ) and Lacitignola et al ( 24 ). In this study, in both groups, Caiman ® (Aesculap—Tuttlingen) was used to perform the surgeries, and there were no intraoperative or postoperative complications.…”
