comparison between two portal laparoscopy and open surgery for ovariectomy in dogs

ovariectomy (ove) is a routine surgical procedure for neutering in small animal practice. laparoscopy is a new surgical technique which contains advantages such as less trauma, smaller incision and excellent visualization than traditional open surgery. the present study was conducted to examine the feasibility and safety of laparoscopic procedure through two portal comparing with the conventional open surgery for ove in healthy female bitches (n=16). dogs were divided in two equal groups. in laparoscopic group, two 5 and 10 mm portals were inserted; first in the umbilicus for introducing the camera and the second, caudal to the umbilicus for inserting the forceps. laparoscopic procedure involved grasping and tacking the ovary to the abdominal wall, followed by electrocautery, resection and removal of the ovary. in open surgery, routine ove was conducted through an incision from umbilicus to caudal midline. mean operative time, total length of scar, blood loss, clinical and blood parameters and all intra and post-operative complications were recorded in both groups. mean operative time, total length of scar, blood loss and post-operative adhesions were significantly less in laparoscopic group compared with open surgery. in conclusion, laparoscopic ove is an acceptable procedure due to more advantages in comparison with traditional ove.
