Objective: To compare the influence of extracorporeal and intracorporeal ligations on the duration of and complications associated with laparoscopic ovariectomy in dogs.
Study Design: Prospective randomized experimental study.
Animals: Healthy intact female dogs (n = 18).
Methods: The left and right ovarian pedicles of dogs undergoing laparoscopic ovariectomy were randomly assigned to intracorporeal (n = 18) or extracorporeal (n = 18) ligation groups. Surgeries were performed by two American College of Veterinary Surgeons (ACVS) diplomates and two ACVS residents. The time required to place extracorporeal and intracorporeal ligations, duration of surgery, and intraoperative complications were compared between ligation techniques. Postoperative complications were recorded.
Results: The time required for intracorporeal ligation (17.3 ± 8.7 minutes) did not differ from that required for extracorporeal ligation (15.1 ± 6.1 minutes; P = .38). The total duration of surgery was 102.7 ± 28.7 minutes including portal placement and veterinary student closure of incisions. Ligation of the ovarian pedicle was successful in 16 of 17 dogs. Intraoperative hemorrhage occurred in three dogs, and postoperative complications were noted in three dogs, without apparent difference between ligation techniques.
Conclusion: No difference was identified between extracorporeal and intracorporeal ligations of ovarian pedicles.
Clinical Significance: This study does not provide evidence to support one ligation technique rather than the other.

This is the case of a 22-year-old female who arrived at our institution after experiencing refractory insomnia, disorganized behavior, inappropriate laughter, and anorexia. Upon admission, a physical examination revealed mutism, irritability, and visual hallucinations. Infectious, metabolic, and other, alternative, causes for the presenting symptoms were excluded.

Acute-phase proteins (APPs) are biomarkers of systemic inflammation, which allow monitoring the response to surgery and post-operative complications. Ovariectomy (OVE) can be a useful model to evaluate surgical trauma and inflammation in feline species. The objective of this study was to evaluate and compare the acute-phase response (APR) after applying two different OVE techniques by measuring serum levels of serum amyloid A (SAA), haptoglobin (Hp), total serum proteins (TSPs), albumin (ALB), and paraoxonase-1 (PON-1) during the first 48 h post-surgery (hospital stay).

Behavioral problems in reproductively healthy mares are a challenging issue that is successfully treated with bilateral ovariectomy (BO). This laparoscopic procedure represents an alternative to conservative treatment for mares not intended for breeding and results in high owner satisfaction regarding behavioral improvement. However, a pathohistological explanation to justify surgical ovarian removal regarding animal welfare is lacking.

Article Synopsis
- The study aimed to evaluate the effectiveness of two different approaches for administering quadratus lumborum block (QLB) in dogs undergoing laparoscopic ovariectomy, focusing on pain control during surgery.
- A total of 15 female dogs were randomly assigned to either a lateral or latero-ventral approach for the QLB, with pain management strategies monitored throughout the procedure.
- Results indicated that the lateral approach significantly reduced the need for additional pain relief during surgery compared to the latero-ventral approach, while all dogs had similar postoperative pain scores.
Is single-port laparoscopy or vaginal natural orifice transluminal endoscopic surgery the better option for salpingo-oophorectomy?

Article Synopsis
- This study aimed to compare postoperative pain and recovery between two surgical methods, single-port laparoscopic surgery (SPLS) and vaginal natural orifice transluminal endoscopic surgery (vNOTES), in patients undergoing oophorectomy.
- Researchers analyzed data from patients who had the surgery between 2016 and 2023, focusing on factors like pain levels and recovery quality.
- Results showed that patients in the vNOTES group experienced less pain and had a higher quality of recovery score compared to those in the SPLS group, even though operating times were similar for both methods.
