title: Standing laparoscopic ovariectomy technique with intraabdominal dissection for removal of large pathologic ovaries in mares.
abstract: OBJECTIVE
  To describe a standing laparoscopic ovariectomy technique with intraabdominal ovarian dissection inside a specimen retrieval bag for removal of large pathologic ovaries through small incisions.
  
  
  METHODS
  Case series.
  
  
  METHODS
  Mares (n=43) aged 2-21 years and weighing 380-680 kg.
  
  
  METHODS
  Unilateral laparoscopic ovariectomy was performed on 43 standing sedated mares. Ovaries were approached via 3 portal sites, 2 in the paralumbar fossa and a 3rd between the 17th and 18th ribs on the ipsilateral side. Ovaries were dissected free using either a LiNA Tripol-bipolar laparoscopic forceps or a Ligasure Vessel Sealing Device and removed by enlarging the proximal portal site ventrally using a grid technique. Use of a plastic specimen retrieval bag and cannula suction device facilitated intraabdominal dissection of very large ovaries into 2 or more pieces, before removal through small incisions.
  
  
  RESULTS
  Regardless of size, all ovaries were removed successfully through small incisions (range, 5-10 cm), with no major complications and an excellent cosmetic result. All sport horses returned to previous levels of work or higher, with 93% of breeding mares successfully bred in the 1st season after surgery.
  
  
  CONCLUSIONS
  Large pathologic ovaries can be easily and safely removed by standing laparoscopic ovariectomy on the mare.
  
  
  CONCLUSIONS
  Standing laparoscopic ovariectomy combined with a small flank incision is a safe and highly effective technique for removal of large pathologic ovaries in the mare, negating the requirement for general anesthesia or large incisions.
