M., Amir Niasari-Naslaji3, DVM, PhD Objective- The purpose of this study was to compare two portal laparoscopy and conventional approach for ovariectomy in queen. Design- Retrospective study. Animals- Adult healthy queens (n=24). Procedures- Queens referred to the small animal hospital, Faculty of Veterinary Medicine, University of Tehran for neutering were randomly assigned for two-portal laparoscopy (n=12) and midline open ovariectomy (conventional approach; n=12). General anesthesia was performed using the combination of ketamin (5.5 mg/kg; i.v.; Ketalar®, Alfasan) and diazepam (0.27 mg/kg; Valium®, Caspian, i.v.) followed by isoflurane in oxygen entubation. Results- Surgical time, length of surgical incisions and recovery time were significantly lower in laparoscopic (11.9±0.95 min, 15.9±0.18 mm, 40.4±4.29 min) compared to conventional ovariectomy (20.7±0.95 min, 27.4±1.27 mm, 58.5±5.58 min; P<0.05). Conclusions- In conclusion, two portals laparoscopy is a simple, safe and suitable approach for elective neutering in queen.
