When is it indicated?
- Ovarian tumoyrs: The most common is the granulosa-theca cell tumour, usually benign but often responsible for hormonal changes leading to aggressive or stallion-like behavior and performance issues.
- Severe behavioral problems: Extreme mood swings or pain during the cycle may improve after removal of one or both ovaries.
- Cysts or abnormalities: Large cysts or malformations can compromise fertility and welfare.
Surgical techniques
At Equitom, three approaches are available:
- Standard laparoscopic ovariectomy (standing)
The most common technique, performed on a standing sedated mare through small flank incisions.- Benefits: minimally invasive, reduced pain, quick recovery
- Laparoscopic removal with morcellation inside a sterile retrieval bag (standing)
Used when the ovary or tumor is too large to remove whole. The tissue is morcellated inside a sterile bag to ensure safe extraction.- Benefit: allows large tumours to be removed laparoscopically.
- Laparotomy (under general anesthesia)
Reserved for extremely large or complex cases where laparoscopy is not possible.
Recovery and aftercare
Most mares recover quickly, especially after laparoscopic procedures. Controlled exercise, pain management, and wound care are key. Behavioral changes linked to hormonal tumors often normalize within weeks to months.
