A two‐step ovariohysterectomy with unilateral left flank laparoscopic assistance in a Quarter Horse mare

Summary This case report describes the technique and outcome of a two‐step laparoscopic‐assisted ovariohysterectomy in a Quarter Horse mare performed through the left paralumbar fossa for the treatment of chronic pyometra. Ovariohysterectomy is a procedure uncommonly performed in the horse. It is surgically demanding, invasive and can be associated with significant complications when a ventral midline approach is performed. Laparoscopic‐assisted techniques reduce the invasiveness and some of the complications associated with ovariohysterectomy through ventral midline alone. The described modification further reduces the invasiveness of laparoscopic‐assisted ovariohysterectomy and has the potential to reduce the overall surgical time of the procedure. Further work is needed to determine if the technique could be extrapolated to large‐sized mares.
