Comparison of conventional vs. electrosurgical ovariosalpingectomy with the EnSeal® tissue sealer in pond sliders (Trachemys scripta): impacts on procedure time, surgical access, and recovery time according to follicular stage

Abstract

Pond sliders (Trachemys scripta) is a common pet and invasive species in many countries. Its ability to thrive and reproduce in Mediterranean climates necessitates population control to prevent overpopulation. Ovariectomy is considered as a preventive strategy to limit reproduction and protect local biodiversity. This study compares two spaying techniques in Trachemys scripta: electrosurgery using the EnSeal® tissue sealer (group E) and a conventional approach with manual ligation of blood vessels (group C). Statistical tests evaluated procedural differences, including ANOVA for duration (factoring in follicular stage, surgery type, and their interaction) and Chi-squared tests for the likelihood of single surgical access via the prefemoral fossa and post-surgical feeding. Pearson’s Chi-squared test with Yates’ correction was used to assess complications by surgery type and follicular stage. ANOVA assessed the effect of follicular stage on surgery time, with follicles classified as Class I (n = 17), Class II (n = 12), and Class III (n = 7). Both follicular stage and surgery type significantly impacted surgery time, while their interaction was not significant, indicating independent effects. The likelihood of single-access procedures was significantly linked to surgery type, with EnSeal® procedures being faster and associated with earlier post-surgical feeding. Complications were not significantly linked to surgery type or follicular stage.
