Laparoscopic Ovariectomy in a Domestic Yak

Abstract EN

Owners of a juvenile domestic yak elected bilateral ovariectomy to prevent future reproduction.

The yak was noted to be healthy at presentation.

Both ovaries were removed using a laparoscopic approach as follows: after induction and maintenance of general inhalant anesthesia, 15 degrees Trendelenburg positioning was required to view the ovaries.

Ovariectomy was conducted within a surgical time of 50 minutes.

Due to the small ovarian size, portal enlargement was not necessary for removal.

Mild hemorrhage from the left ovarian pedicle was controlled with application of a vessel-sealing device.

Postoperative complications were not encountered during hospitalization.

At 12 months following surgery, the yak was healthy, and the owner was highly satisfied with the procedure.

The described approach was successful for performing laparoscopic ovariectomy in a juvenile yak.

Positioning for surgery was similar to other small ruminant species.

Further case enrollment is needed to optimize the surgical approach and better describe clinical outcomes.
