Complications associated with laparoscopic ovariectomy in mares

Two‐Step Surgery Combining Standing Laparoscopy With Recumbent Ventral Median Celiotomy for Removal of Enlarged Pathologic Ovaries in 20 Mares

“…Ligation and transection of the ovarian pedicle are reported to be easier in the standing laparoscopic approach than in dorsal recumbency. Laparoscopic ovariectomy in the standing sedated mare allows normal anatomic orientation, easier intra‐abdominal manipulation, and avoids the risks of general anesthesia . Moreover, the laparoscopic approach under anesthesia is technically more difficult, requires additional training, and ovarian size can compromise viewing .…”

“…Moreover, the laparoscopic approach under anesthesia is technically more difficult, requires additional training, and ovarian size can compromise viewing . With laparoscopy in dorsal recumbency, the mare needs to be placed in the Trendelenburg position, which increases the potential for cardiovascular anesthetic complications . Excessive traction on the ovarian pedicle can result in intraoperative hypotension, which is believed to contribute to myopathy and neuropathy…”

“…Incisional complications are reported to occur in mares with enlarged ovarian diameter. Greet describes a case with a severe subperitoneal swelling and seroma in the flank incision . Hypothetical cause was similar to the process that causes hygroma formation after chronic injury, or similar to adenomucinosis that occurs in people after laparoscopic intestinal resection, and when a piece of rectal mucosa becomes entrapped in the subperitoneal space.…”

Standing open‐flank approach for removal of enlarged pathologic ovaries in mares

“…Several reports describe successful removal of enlarged pathologic ovaries via laparoscopy (De Bont and others 2010, Kummer and others 2010, Lloyd and others 2007). Nevertheless, laparoscopy requires expensive equipment, special expertise and exposes the surgeon to multiple unique complications, such as in situ instrument failure, retroperitoneal insufflation, damage to abdominal viscera and vascular damage (Desmaizieres and others 2003, Greet 2012). Performing the surgery using an open‐flank approach, it was possible to safely remove enlarged ovaries in an efficient manner while avoiding these potential drawbacks of laparoscopy.…”
