OBJECTIVES AND METHODS: The laparoscopic surgery as well video-assisted surgery are not novel surgical
modalities, but additional options to conduct a surgical procedure, thereby requiring an adaptation phase (1). The major
disadvantage of laparoscopy is the high cost of equipment; require more than one surgeon to perform; and the progress in
the learning curve (2). The search for techniques to facilitate laparoscopy and is suitable for the animal size has been the
subject of several studies. Thus, the objective of this study was to evaluate the feasible of video-assisted
ovariohysterectomy in cats using two portals. Fifty two healthy queens, weighing more than 2.0 Kg and aged 1.5 years
were used. All procedures were performed by the same surgeon. The females were anesthetized and the abdomen was
insufflated to a maximum pressure of 8 mmHg with CO2 gas using a 5 mm cannula with valve (first trocar), which was
positioned in the cranial region to umbilical scar (Figure 1). Then, the endoscope (5 mm, 0°) was introduced in first trocar.
The second trocar was placed in the midline of pre-pubic region. The female was turned to lateral position to show the
uterine horn and right ovary. A Babcock forceps was introduced in the second trocar to elevate and to fix (transcutaneous
external suture) the uterine horn and ovary up to lateral region of abdominal wall. The ovary suspensory ligament was
disrupted with Babcock forceps and the ovarian pedicle was cauterized on three parallel points with a bipolar electrocautery
forceps. Pedicle was sectioned in the middle cauterized portion. The same procedure was carried out in left pedicle. The
queen was repositioned in dorsal supine and ovaries pulled through the second trocar. The uterine body exposed was
transfixed using mononylon and sectioned. The two incisions were sutured.
RESULTS: The mean and standard deviation of total surgical time was 41.4  14.2 minutes. All females had adequate
recovery from anesthesia, without excitement or complications. We have found the following complications: hemorrhage
(1.9%), hypotension (7.7%), subcutaneous emphysema (7.7%), dehiscence (1.9%), hematoma (1.9%) and conversion to
laparotomy (13.5%).
CONCLUSION: The complications were similar to findings of Solomon et al. (3), which reported decrease of the surgical
time, and complications after the first 10 procedures, remaining stable in next. The conversion of the videosurgery to
laparotomy was a major complication and according to Adikibi et al. (5) should not be considered a complication but an
attribute to the learning curve. In this study was used only two trocars because the abdomen of the cats is small, which
justifies the reduction in the portal numbers (5). The transcutaneous external suture dispensed the third trocar, a technique
previously shown in dogs (6). The video-assisted surgery using two portals, described in this study was adequate and safe
for performing ovariohysterectomy and it can be an additional option to domestic cats.
