COMPARATIVE STUDY OF FELINE OVARIOHISTERECTOMY BY THE FLANK AND
MIDLINE APPROACHES
ABSTRACT
Ovariohysterectomy is one of the most frequently performed surgical procedures in
veterinary practice in order to control pet population. In cats the recommended age to
perform ovariohysterectomy is 6 months and it’s always advisable before the puberty.
The objective of this study was to compare two different approaches for ovariohysterectomy:
by the flank and by the midline. Twenty-four ovariohisterectomies were performed, 13 by the
flank approach and 11 by the midline. The cats were healthy, with 4 to 24 months and were
not in oestrus, lactating or pregnant. The duration of each part of the procedures was
recorded, as well as the final length of the incision and the intra and postoperative
complications. The total duration of the surgery was significantly lower in the flank approach
(p= 0,012). The only part of the surgery where the time was similar between the two
approaches was during exteriorization and suture of the uterine body. In all the other times
the midline approach took significantly longer. The mean final length of the flank incisions
was significantly shorter (p= 0.001). The great disadvantage of the flank approach is the lack
of visibility of the abdominal cavity, which consequently increases the intraoperative
complications. It was recorded a case of hemorrhage for loss of the ovarian pedicle before it
was sutured. Additionally, there was a higher incidence of postoperative complications in this
approach, detected in 4 cases. In the midline approach, only one cat had postoperative
complication.
