The rational
complications are considered, is that either technique can
be used for canine female gonadectomy. The surgeon has
to choose the least invasive, fastest, and safest procedure.
A major advantage of OVE is that it can be performed
through a smaller celiotomy and with less traction on the
female genital tract. Technically, OVH is more complicated
(more tissue is ligated and transected), time consuming
(because a larger celiotomy is needed to expose
the entire uterus) and is therefore expected to be associated
with a greater short-term morbidity when compared
with OVE. However, differences in short-term
postoperative morbidity between the 2 techniques have
not been published. Increased risk for surgery-related
complications associated with OVH are estimated for:
intraabdominal and vaginal bleeding (because of larger
vessel diameter near the uterine body), ureteral ligation
(because of close proximity of the distal part of the ureter
to the uterine body), ovarian remnants (because of the
more caudally located incision), uterine stump complications,
and sinus tracts (because of mucosal exposure).
Since 1981, after introduction of OVE as the standard
technique for canine neutering at Utrecht University, no
increase in short-term complications has been observed.
With respect to long-term urogenital problems, including
endometritis/pyometra and urinary incontinence, it has
been clearly established that they do not occur more frequently
with either technique. The overall chance for development
of malignant uterine tumors is very low
(0.003%), and, in our opinion, does not warrant performing
a potentially more traumatizing surgical procedure,
OVH, that might be associated with more
postoperative complications.
Without benefit of more prospective studies comparing
surgical complications between OVE and OVH, most
evidence extracted from the literature leads us to the
conclusion that there is no benefit and thus no indication
for removing the uterus during routine neutering in
healthy bitches. Thus we believe that OVE should be the
procedure of choice for canine gonadectomy.
