Effects of Leaving Amputated Ovaries Intra-Abdominally during Elective Bilateral Standing Laparoscopic Ovariectomy in Equids.
Abstract: There is risk of dropping an amputated ovary within the abdomen during standing laparoscopic ovariectomies in mares. If the ovary can no longer be directly visualized with the laparoscope, the procedure is then converted to a flank laparotomy for manual retrieval of the ovary which negates the minimally invasive nature of the laparoscopic procedure. The objective was to identify if ovaries left in the abdomen after amputation would atrophy or if they re-vascularize. Standing bilateral ovariectomies were performed in mature mares, but after transection of the ovarian pedicle, the ovaries were intentionally dropped and left within the abdomen. Post-operative endocrine values were at basal levels and an improvement in all mare's behavior and general herd dynamics was observed. While this study does not encourage to leave ovaries in the abdomen after amputation, we report no complication related to their voluntary release into the abdomen.

This study investigates the implications of leaving amputated ovaries in the abdomen during procedures for equids. The findings reveal that this practice does not result in complications, with no recorded evidence of revascularization of the amputated ovaries.
Objective of Research
- This research was aimed at understanding the effects of leaving amputated ovaries in the abdomen after performing elective bilateral standing laparoscopic ovariectomies on equids. This is a common issue which often renders the whole process of laparoscopy futile by requiring a flank laparotomy to locate and remove the ovary, especially when it is no longer directly visible.
Procedure
- During the study, standing bilateral ovariectomies were performed on mature mares.
- The distinctive aspect of the process was that after the transection of the ovarian pedicle, the ovaries were purposefully dropped and left within the abdomen. This unusual step was necessary to study the reactions and eventual outcomes of ovarian retention in the body.
Findings
- Following the aforementioned procedure, the endocrine values post-operation decreased to basal levels.
- Another noteworthy finding was the improvements observed in the mares’ behaviour as well as overall herd dynamics. This emphasizes the potential positive impacts of the procedure on the mares.
- However, the study did not indicate any evidence of revascularization, or the natural process of new blood vessel formation, in the amputated ovaries.
Conclusion
- None of the mares in this study suffered any complications due to the retained amputated ovaries.
- Even though the study does not endorse the practice of leaving amputated ovaries within the body, it provides significant insights into the potential effects of such a situation. It concludes that the retention of ovaries does not seem to cause any short-term issues, but it encourages further research on possible long-term risks and effects.
