Plain-English summary
A group of 27 dogs underwent a new type of surgery called laparoendoscopic single-site ovariectomy, which is a minimally invasive way to remove the ovaries. The surgeries were performed by an experienced veterinarian, and while there were some minor complications like a small hemorrhage and an infection, all dogs recovered well. Owners reported high satisfaction with the procedure, and the surgeon was able to improve their skills quickly, needing about eight surgeries to reach optimal performance. Overall, this technique showed promising results for spaying dogs with minimal recovery issues.

Abstract
OBJECTIVE: To define the learning curve and evaluate the outcome for a board-certified veterinary surgeon performing laparoendoscopic single-site (LESS) ovariectomy in dogs. DESIGN: Retrospective case review and learning curve evaluation with a skill acquisition model. Animals-27 client-owned dogs. Procedures-Between April 2011 and December 2012, 27 dogs underwent elective LESS ovariectomy performed by a single experienced board-certified laparoscopic surgeon by means of the same technique. Medical records for these patients were reviewed to determine whether a learning curve could be detected. A commercially available multitrocar port was inserted through a 15- to 20-mm incision at the umbilicus, and LESS ovariectomy was performed with articulating graspers, a bipolar vessel-sealing device, and a 30° telescope. Surgical performance of the surgeon was quantified with an exponential skill acquisition model, and how skill was gained with repetition of the same novel surgical procedure was examined. RESULTS: Median patient body weight was 20 kg (44 lb; range, 3.5 to 41 kg [7.7 to 90.2 lb]). Median surgical time was 35 minutes (range, 20 to 80 minutes). Median patient age was 314 days (range, 176 to 2,913 days). The skill acquisition model revealed that a comparable surgeon could reach 90% of optimal surgery performance after approximately 8 procedures (8.6, 95% confidence interval, 0.5 to 16.6 procedures). According to the model, with each surgery, surgical time would be expected to decrease by 27% (95% confidence interval, 2% to 52%). Complications were limited to minor hemorrhage due to a splenic laceration and a postoperative incisional infection. Follow-up information was available for all 27 cases. All owners were satisfied and indicated that they would pursue LESS ovariectomy again. CONCLUSIONS AND CLINICAL RELEVANCE: The learning curve for LESS ovariectomy was short and definable. Short-term outcome was excellent. Results of this study suggested that an experienced laparoscopic surgeon may anticipate achieving proficiency with this technique after performing approximately 8 procedures.
