Single incision laparoscopic-assisted ovariohysterectomy for an ovarian tumor in a dog.

This report describes a single-incision, laparoscopic-assisted ovariohysterectomy in a 6-year-old, intact female Keeshond dog for the staging and treatment of a left-sided ovarian tumor. Abdominal access was obtained using a modified-Hasson technique allowing for placement of a multi-channel, single incision laparoscopic surgery port. Following carbon dioxide insufflation, superficial laparoscopic exploration of the abdominal cavity was performed and then both ovarian pedicles were sealed and divided using a vessel-sealing device. Laparoscopic-assisted ovariohysterectomy was performed with the aid of a wound retractor for exteriorization of the mass. There were no perioperative complications and the patient was discharged 1 day after surgery. Histopathology of the mass revealed an ovarian teratoma. Telephone follow-up 608 days after surgery revealed a good clinical outcome. Single-incision, laparoscopic-assisted ovariohysterectomy is technically feasible for the treatment of selected ovarian tumors in the dog.
