Design-Elective experimental study Animals- Twenty four mixed breed healthy adult female dogs. Procedures-The dogs divided into two equal groups. Laparoscopic ovariohysterectomy performed using either monopolar (n=12) or bipolar (n=12) electrocoagulation. Under general anesthesia, dorsal recumbency and reverse trendelenburg position a 10 mm portal for camera insertion at the umbilicus. Two other 5 mm portals were placed 5 cm cranial and caudal to umbilicus in both groups. Monopolar electrocauter were used for coagulation and cutting but bipolar electrocauter were used for coagulation only. Following identification of ovaries, suspensory ligament, ovarian vessels, broad ligament and uterine vessels and body were coagulated and cut. The pedicles were checked for any signs of hemorrhage. Ovaries, broad ligament and uterus were removed from the abdomen through umbilical portals. Results-There were no significant differences between surgical time and the amount of hemorrhage in both groups. Significant differences observed in degrees of the released smoke and tissue burning between groups. Conclusion- As a whole we concluded that the bipolar electrocauter was superior to monopolar electrocoagulator in laparoscopic ovariohysterectomy and has the advantages of decreasing released smoke and burnt tissue compare to that of monopolar electrocauter. %U https://www.ivsajournals.com/article_3140_aed5a470c4b77866abf2d86cfc86bacb.pdf
