Objective—To describe a simple method of laparoscopic-assisted ovariohysterectomy (LAOHE) and
compare duration of surgery, complications, measures
of surgical stress, and postoperative pain with
open ovariohysterectomy (OHE) in dogs.
Procedures—Dogs were randomly allocated to
receive conventional OHE or LAOHE. Intraoperative
complications, anesthetic complications, total anesthesia
time, and total surgery time were recorded.
Serum cortisol and glucose concentrations, temperature,
heart rate, and respiratory rate were measured
preoperatively and 1, 2, 4, 6, 12, and 24 hours postoperatively.
Pain scores were assigned by a nonblinded
observer at 1, 2, 4, 6, 12, and 24 hours postoperatively.
Duration of surgery, pain scores, objective
measures of surgical stress, anesthetic complications,
and surgical complications were compared
between OHE and LAOHE.
Results—Age, weight, PCV, and duration of surgery
did not differ between treatment groups. Nine of 10
dogs in the OHE group required additional pain medication
on the basis of pain scores, whereas none of
the dogs in the LAOHE group did. Blood glucose concentrations
were significantly increased from preoperative
concentrations in the OHE group at 1, 2, 4,
and 6 hours postoperatively and at 1 hour postoperatively
in the LAOHE group. Cortisol concentrations
were significantly increased at 1 and 2 hours postoperatively
in the OHE group.
Conclusions and Clinical Relevance—LAOHE caused
less pain and surgical stress than OHE and may be more
appropriate for an outpatient setting. (J Am Vet Med
