Objective To compare technical feasibility, surgical time, surgical complications, and postoperative pain in ovariectomy (OVE) by hybrid and total natural orifice transluminal endoscopic surgery (NOTES). Study design Prospective randomized clinical trial. Animals Sixteen healthy and sexually intact bitches. Methods Dogs were randomly assigned to the hybrid NOTES group (HNG; n = 8) and the total NOTES group (TNG; n = 8) to compare surgical time, pain scores and complications. Pain was assessed by using the visual analog scale (VAS) and the Melbourne pain scale (MPS). Results Surgical time did not differ between the experimental groups (HNG = 46.3 ± 18.5 minutes, TNG = 54.6 ± 31.1 minutes). Exteriorization of the ovaries through the vaginal wound was the major difficulty. Complications were minor in both groups and occurred intraoperatively only in the HNG, and in both groups post operatively. No dogs required rescue analgesia in the intraoperative or postoperative period. There were no differences in VAS or MPS scores between the groups for any surgical times except for the VAS assessment at 72 hours after extubation (HNG = 1.1 ± 0.3, TNG = 0.7 ± 0.4, P = .0221). Conclusion Both NOTES techniques were comparable for canine OVE, with no requirement for additional analgesia in the postoperative periods. It was not possible to determine whether there was a clear advantage of one technique rather than the other. Clinical significance The minimally invasive techniques proposed for laparoscopic OVE are feasible for dogs with low pain scores and low rates of complications for both groups.
