Ovary: ovariohysterectomy – laparotomy approach
Introduction
- Ovariohysterectomy is rarely performed in horses.
- It is technically demanding, highly invasive and associated with high morbidity.
Uses
- Chronic pyometra Uterus: pyometra (unresponsive to medical management).
- Intramural hematoma.
- Uterine neoplasia (leiomyoma, leiomyosarcoma).
- Macerated fetus.
- Mucometra.
- Chronic uterine torsion Uterus: torsion .
- Uterine rupture.
Advantages
- Laparoscopic equipment and training not required.
- May be appropriate for removal of severely enlarged uterus.
Disadvantages
- Very invasive, large incision.
- High morbidity.
- Poor intra-operative visibility.
- Poor intra-operative exposure.
- Excessive post-operative morbidity.
Alternative techniques
- Hand assisted laparoscopy Ovary: ovariectomy - laparoscopic approach .
- Combined approach, where the majority of dissection is performed laparoscopically under standing sedation Anesthesia: standing chemical restraint ; the uterus is then exteriorized under general anesthesia Anesthesia: general - overview using a caudal ventral laparotomy incision.
