Total and partial ovariohysterectomy in seven mares.
- Journal Article
Summary
This research article investigates the effectiveness and risks associated with ovariohysterectomy in mares, and it finds the procedure to be a viable treatment for various uterine diseases, despite its technical complexity and some life-threatening complications.
Objective and Methods
The study aims to demonstrate the effectiveness of ovariohysterectomy (removal of the ovaries and uterus) as a treatment for a range of uterine diseases in mares. This is accomplished by evaluating the medical records of seven mares that underwent this procedure at the University of Illinois between 1994 and 2001. The researchers meticulously recorded and evaluated the diagnosis, clinical data, applied surgical technique, post-operative care, any resulting complications, and the final outcome.
Indications and Surgical Techniques
- The mares were chosen for the operation due to various health conditions such as chronic pyometra, uterine torsion and intramural hematoma.
- The surgical procedure was found to be challenging due to the difficulty in gaining exposure. However, the use of traction on stay sutures and right-angled clamps improved the situation.
- In some cases, the application of a specific instrument (TA-90 autosuture) as a right-angled clamp on the hind part of the uterus was observed to facilitate better access to the uterine stump.
Post-Operative Complications
- Decreased fecal output and reduced intestinal sounds were seen in four mares following the surgery. Also, mild bouts of abdominal pain were noticed in two mares.
- Incisional infections of mild to moderate intensity were observed in two mares.
- However, more serious complications commonly associated with such surgeries, like hemorrhaging, septic peritonitis, uterine stump infection or necrosis, and diarrhea, were not observed in any of the mares.
Outcomes and Conclusions
- All the mares survived for a follow-up period ranging from six months to five years post-operation. They were used for riding and in one case, for embryo transfer (after partial ovariohysterectomy).
- Despite the technical difficulties and risks identified, the study concludes that the prognosis for mares post ovariohysterectomy appears to be good.
- The likelihood of life-threatening complications could potentially be lower than what is generally reported.
