The aim of the study was to compare the use of open ovariectomy, to the video-assisted laparoscopic approach or total laparoscopic ovariectomy in Santa Ines ewes. Surgical time and body weight gain/loss were recorded and post-surgical pain assessed using a behavioral scale. Laparotomy involved a longer surgical time (75 ± 29.5 min), than the video-assisted (37.5 ± 13.04 min; p < 0.05) or total laparoscopic approach (27.5 ± 2.89; p < 0.01). Behavioral pain recorded score was higher for the laparotomy ovariectomy (5.6 ± 0.5), compared to the video-assisted (0.3 ± 0.5) and laparoscopic approaches (0.3 ± 0.5) (p < 0.0001). No significant differences were recorded regarding body weight gain/loss during the first 30 days post-surgery, between the techniques. The video-assisted laparoscopic and total laparoscopic techniques of ovariectomy showed a tendency to have more advantages than the use of laparotomy as such. Less surgical trauma, a shorter surgical time, minimal postsurgical stress and better surgical recovery being highlighted as the main advantages of the endoscopic approaches in sheep.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
