Feasibility of single-portal access laparoscopic ovariectomy in 17 cats

Abstract

Laparoscopic ovariectomy (LapOVE) using single-portal access was attempted in 17 clientowned cats of different breeds admitted for elective ovariectomy. A 12 mm umbilical portal was placed 1 cm caudal to the umbilicus with the cat in dorsal recumbency. Then, a laparoscope with an operating channel was introduced into the portal with the cat in lateral recumbency. The right ovary was pulled to the abdominal wall using grasping forceps and fixed to the abdominal wall by a transabdominal suspension suture. The ovarian vasculature, suspensory ligament and proper ligament were progressively cauterised and transected with multifunction bipolar electrocoagulation forceps. The resected right ovary was exteriorised through the umbilical portal cannula. The left ovary was then removed from the abdomen in a similar fashion. Surgical time, intraoperative haemorrhage, amount of fat in the ovarian ligament, surgical complications and postoperative pain were recorded. The mean (sd) surgical time was 23 minutes and seven seconds (five minutes and 55 seconds). Intraoperative blood loss and fat deposition of the ovarian ligament were minimal. No intra-and postoperative complications were encountered. No cats needed rescue analgesia within 24 hours postsurgery.
