CASE DESCRIPTION 7 privately owned female African lions (Panthera leo) that had been bred for public exhibition and were housed in outdoor pens were evaluated prior to undergoing elective ovariectomy.

CLINICAL FINDINGS All animals were healthy. Median age was 15 months (range, 9 to 34 months), and median body weight was 71 kg (156 lb; range, 48 to 145 kg [106 to 319 lb]).

TREATMENT AND OUTCOME Surgical sterilization by means of single-incision laparoscopic ovariectomy was elected. A 2- to 3-cm-long skin incision was made just caudal to the umbilicus, and a single-port multiple-access device was bluntly inserted through the incision. Traction was maintained with stay sutures to provide counterpressure, and three 5-mm-diameter cannulae were introduced through the device's access channels with a blunt trocar. The abdomen was insufflated to a pressure of 12 mm Hg with CO2. Each ovary was grasped and suspended with a standard 36-cm-long laparoscopic grasper, and ovariectomy was performed with a 5-mm vessel sealer and divider device. Because of the depth of subcutaneous fat, extensive subcutaneous dissection was necessary to insert the single-port device. In contrast, fat content of the mesovarium was minimal and did not vary markedly among animals. Subjectively, single-incision laparoscopic ovariectomy was easily performed, but all surgeons had experience in laparoscopic surgery. Median duration of the surgical procedure was 29 minutes (range, 21 to 49 minutes). No perioperative complications were encountered.

CLINICAL RELEVANCE Findings suggested that the single-incision laparoscopic technique may be an acceptable, minimally invasive option for ovariectomy of large felids.

A 10-month-old male crossbred dog presented with a 4-week history of polyuria and polydipsia and a 6-month history of vomiting.


Clinical examination revealed abdominal pain and right-sided nephromegaly. Biochemistry was within normal limits. Diagnostic imaging showed a well-defined, unilateral renal mass containing anechoic fluid consistent with a simple renal cyst (SRC).


The cyst was drained under ultrasonographic guidance but recurred 3 months later, concomitant with recurrence of the previously reported clinical signs. The cyst was then deroofed, fulgurated, and omentalized under laparoscopy by use of a 3-port technique. The resected cystic wall was histopathologically consistent with an SRC, presumptively congenital. The dog showed a good recovery with resolution of clinical signs. Renal function was normal at last follow-up, conducted 2 years postoperatively, without evidence of recurrent disease.


To our knowledge, this was the first report of a symptomatic juvenile SRC of presumptively congenital origin in a dog treated successfully by laparoscopic deroofing, fulguration, and omentalization. The polyuria, polydipsia, chronic vomiting, and abdominal pain may all have been related to space-occupying effects of the cyst, as these symptoms resolved post-treatment. Results of long-term follow-up advocate for this durable cure of SRC by use of laparoscopic procedures, especially when compared to simple drainage of the cyst, as the latter initially failed in the present case.
