“…The anatomical differences between species in veterinary medicine make the acquisition of manual skills more complex, leading to an increase in surgical times and explaining the statistically significant difference detected ( p < 0.05). Laparoscopic surgery has been described in mammals as rats, guinea pigs, rabbits, and capybaras [ 30 , 31 , 32 , 33 , 34 ], but no reports regarding nutrias were found; a comparison between laparoscopic vs. laparotomic ovariectomy (mean surgical time: 43 min vs. 22 min) was carried out in rabbits [ 28 ] with results comparable to the present study. The insufflation of the abdomen and the positioning of the trocars require a certain amount of time, spared if an open technique is used.…”

The nutria (Myocastor coypus), an invasive alien species, is widely spread in Europe. Pursuant to regulation (EU) no. 1143/2014, the nutria is subject to management programs to reduce its spread. Surgical fertility control is considered an acceptable method, particularly in urban circumstances, avoiding euthanasia. To maintain the hormonal patterns and the social and behavioral dynamics, surgical infertilization preserving the gonads (i.e., salpingectomy and vasectomy) is recommended. Mini-invasive surgery is an eligible choice when dealing with wildlife, allowing reduced captivation time. For these reasons, 77 free-ranging nutrias, captured in urban nuclei in Italy, underwent infertilization under general anesthesia; laparoscopic salpingectomy and vasectomy were performed on 32 animals and traditional surgery on the remainder, leaving the gonads in place. A three-port technique was used, with two paramedian trocars (5 mm) for the instruments and a median one for the telescope. Ablation was obtained through Onemytis® plasma device, allowing a rapid surgical time with no need to place visceral sutures; the skin was surgically closed. After recovery, the animals were released, and no overt complications were noted. No modification of the behavioral patterns was noted, and the population decreased during the following months.
