Feasibility of single‐portal access laparoscopic ovariectomy in 17 cats

Abstract

Laparoscopic ovariectomy (LapOVE) using single-portal access was attempted in 17 client-owned 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.

Cardiopulmonary Effects of Laparoscopic Ovariectomy of Variable Duration in Cats

“…In cats, laparoscopic procedures include ovariectomy (OVE), ovariohysterectomy, liver biopsy, pancreatic biopsy, adrenalectomy, splenectomy, cystotomy, and other techniques . Possible advantages of laparoscopic surgery include superior viewing during surgery, reduced risk of hemorrhage, reduced pain in the postoperative period and reduced risk of infection …”

LESS ovariohysterectomy in cats using a new homemade multiport

“…Few studies regarding learning curve of laparoscopic or lap-assisted OVH were carried out on feline specie (TAVARES et al, 2016). Single-port access was sparsely reported in cats (KIM et al, 2011). Moreover, to the authors' knowledge, there is a gap in the literature regarding LESS access for feline spay.…”

Single-port laparoscopic ovariectomy using a pre-tied loop ligature in Santa Ines ewes

“…Reproductive tract was easily visualized using such technique, due to the pneumoperitoneum, Trendelenburg positioning and amplification of the image using the video system. Single portal techniques for ovariectomy have also been reported as feasible and safe in others domestic species, specially in dogs (DUPRÉ et al, 2009;MANASSERO et al, 2012) and cats (KIM et al, 2011;COISMAN et al, 2014). A 3-port laparoscopic assisted ovariohysterectomy technique using pretied loop ligature was assessed in the canine specie, which resulted in bleeding in three dogs (MAYHEW & BROWN, 2007).…”
