Evaluation of a Motorized Morcellator for Laparoscopic Removal of Granulosa-Theca Cell Tumors in Standing Mares

Abstract

A motorized morcellator is a safe and minimally invasive technique for laparoscopic removal of GCT in mares.

Laparoscopic removal of a large abdominal foreign body granuloma using single incision laparoscopic surgery (SILS) and extraction bag in a cheetah (Acinonyx jubatus)

“…Depending on the structural content size, the 20 mm SILS incision might be large enough for retrieval compared with a 10 mm incision for individual ports; however, this has not been determined. Morcillators have been used during granulosa-theca cell tumours resection (Kummer and others 2010) and laparoscopic ovariectomy (Lund and others 2014) in mares. During this procedure, tissue is morcellated (minced) inside a bag or pouch and suctioned out to avoid enlargement of the incision site.…”

Treatment of haemoperitoneum secondary to ruptured granulosa cell tumours in two mares

“…However, there is the additional associated risk and cost of general anaesthesia to consider. Alternatively, aspiration of the fluid contents of the mass or further dissection of enlarged ovaries with a morcellator into smaller size pieces in a specimen retrieval bag via a flank incision has been reported (de Bont et al 2010;Kummer et al 2010), but we believe that this would not have been a realistic option in our two cases due to the size of the ovaries.…”

“…There is a good prognosis following standing laparoscopic removal of large, pathological ovaries and low complication rates are reported: 99-100% of cases are reported to return to their previous level of work and 85-93% of cases are successfully bred within 30 months after surgery (Hubert et al 2006;Lloyd et al 2007;de Bont et al 2010;Kummer et al 2010;R€ ocken et al 2011;Kelmer et al 2013). Short-term survival rates for HP vary from 39 to 74% (Pusterla et al 2005;Dechant et al 2006;Conwell et al 2010).…”

“…There are many choices for surgical ligation of thickened ovarian pedicles including bipolar electrocautery with or without suturing, stapling of the mesovarium and the use of endoscopic clips (Doran et al 1988;Lloyd et al 2007;Smith and Mair 2008;de Bont et al 2010;Kummer et al 2010;Goodin et al 2011). Whichever method is used, care must be taken that haemostasis is complete and secure.…”

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).…”
