Laparoscopic ovariectomy was performed in two Asiatic black bears ( Ursus thibetanus ). Bears were placed in a 20° Trendelenburg position on a surgical table. A three-portal technique was used. A camera port was established 10 cm caudal to the umbilicus with a 5-mm cannula. Two instrument ports were made 1 cm caudal to the umbilicus with a 5-mm cannula and 8 cm caudal to the camera port with a 12-mm cannula, respectively. The suspensory ligament, ovarian vasculature, and uterine horn tip were progressively dissected following coagulation with the Sonicision™ cordless ultrasonic dissection device. The resected ovary was exteriorized through the 12-mm instrument portal site but enlarged to a 2-cm incision length. The abdominal musculature, subcutaneous tissue, and skin of the portal sites were closed separately. Total surgical time was 113 min (Bear A) and 49 min (Bear B), and no postoperative complications were encountered. This is the first report of laparoscopic ovariectomy in the Asiatic black bear.

Uterine inversion is a rare condition that refers to the collapse of the fundus into the uterine cavity and occurs in puerperal and non-puerperal conditions. Non-puerperal uterine inversion is particularly infrequent. Diagnosing non-puerperal uterine inversion is often challenging because it resembles vaginal or cervical tumors and pelvic organ prolapse.

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).

Background: Approaches to paediatric ovarian tumours vary. Cross-sectional imaging is reliable but not always performed. Laparoscopic tumourectomy, although popular, is not recommended by International Paediatric Surgical Oncology Society (IPSO); tumour spillage remains the main concern.
