“…Paraovarian cysts have been described in domestic animal species including sheep and wild felids including cheetahs, lions and tigers, with parauterine (PU) cysts being reported in the lion [5,6,8,30]. Ultrasonography is the primary and preferred imaging modality for anechoic cystic structures visualised in women and these include follicles, functional follicular cysts, early CL's, PO cysts, and the convoluted appearing hydrosalpinx [31].…”

Ultrasonographic and laparoscopic evaluation of the reproductive tract in older captive female cheetahs (Acinonyx jubatus)

The study uniquely described the clinical value of trans-abdominal ultrasonography for monitoring features characterising the oestrous cycle in female cheetahs (Acinonyx jubatus). The reproductive tracts of 21 female, nulliparous and relatively aged (median: 11 and interquartile range: 9.25 -14 years) captive cheetahs resident on two sites in Namibia were assessed by trans-abdominal ultrasound. Subsequently, the ovarian findings on ultrasound were compared with direct visualisation whilst performing laparoscopic sterilization. A combination of these observations supported by concurrent sampling for vaginal cytology and serum progesterone concentrations (SPC) defined the oestrous status of individual animals. At one site, six cheetahs had been implanted with the GnRH agonist, deslorelin as a contraceptive at least once within the preceding 11 years. On ultrasound, 31 uterine horns and 35 ovaries with discernible structures on 28 (86%) were visualised in the 21 cheetahs. The uterine body was difficult to visualise due to its intrapelvic location. Eleven of 19 uteri (58%) visualised showed endometrial oedema suggestive of oestrogenisation. The uteri of four cheetahs (19%) showed evidence of mild cystic endometrial hyperplasia (CEH). Paraovarian (PO) cysts were seen on ultrasound (n = 21) and laparoscopy (n = 26) in 16 (76.2%) and 18 (85.7%) cheetahs respectively. Ovarian volumes obtained from ultrasonographically determined dimensions predicted cyclic activity. Laparoscopy showed that 19 ovaries had discernible follicular structures. In the study population, 10 (47.6%) were in pro-oestrus or oestrus; none in the luteal phase and 11 (52.4%) in anoestrus. Trans-abdominal ultrasound in combination with SPC and vaginal cytology was used with acceptable accuracy to assess cyclic ovarian activity in captive cheetahs. A considerable 1 proportion of this aged population showed ovarian activity and the prevalence of PO cysts was notable. A history of prior deslorelin treatment was not associated with either reproductive activity or uterine pathology

“…Sterilization using various laparoscopic techniques are described in tigers and lions and similarly proved an appropriate surgical technique for captive cheetahs, being both rapid and with low complication rates that facilitated the postoperative care of these wild felids [22,30,32].…”

“…The use of extraction bags or pouches to remove abdominal structures has not been described in large cats. They have however been used for laparoscopic cryptorchidectomy (Spinella and others 2003), adrenalectomy (Naan and others 2013), nephrectomy (Kim and others 2013), cholecystectomy (Lee and others 2011) and splenectomy (Bakhtiari and others 2011) in dogs and ovariectomy in horses (Hanrath and Rodgerson 2002, Rodgerson and others 2002, Hoogmoed and Galuppo 2005, Bont and others 2010) and tigers (Emerson and others 2013) using three or four separate ports. The use of these bags or pouches has also not been described with SILS.…”

This case presents a thorn‐induced abdominal foreign body granuloma that was removed with single incision laparoscopic surgery and an extraction bag. An 11‐year‐old female cheetah presented for routine laparoscopic ovariectomy. Abdominal palpation detected a mid‐abdominal mass. Differential diagnoses were neoplasia and foreign body. Laparoscopic exploration of the peritoneal cavity revealed an omentalised mass, which was successfully removed with the aid of bipolar electrocoagulation. Microscopic investigation intraoperatively and postoperatively confirmed extensive foreign body‐induced granulomatous inflammation. The foreign body was well encapsulated by fibrous tissue with no adjacent stricture formation. The patient made a complete recovery, and this is the first case report of a thorn‐induced abdominal foreign body removed with minimally invasive surgery in a wild African carnivore.

“…[6][7][8] Laparoscopic techniques including ovariectomy have been previously described for several zoologic species including rabbits, pigs, bears, lions, and tigers. [9][10][11][12][13][14][15] In general, the author has been particularly impressed with the faster recovery and return to normal behaviors following laparoscopic ovariectomy versus traditional laparotomy in these exotic species.…”
