This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Management of rectal tears. Rectal tears have important medicolegal implications, and severe tears have a poor prognosis. Prompt diagnosis, immediate application of first aid measures, early referral, use of appropriate definitive treatments, and aggressive aftercare will improve the prognosis. The grade of rectal injury will determine the definitive treatment, but there are few guidelines to determine which treatment is best in each case. Bypass procedures, such as colostomy and indwelling rectal liner, have their own advantages and disadvantages, but can facilitate healing and prevent life-threatening complications if ...
Diseases and surgery of the small colon. Diseases of the small colon are numerous and they can affect horses of any age. Diseases can be simple obstructions, nonstrangulating obstructions, strangulating obstructions, and congenital defects. American Miniature Horses appear prone to luminal obstruction with impacted intestinal contents, and some ischemic diseases are more common in postpartum mares. Enterotomy and enterectomy have a high success rate in the small colon, provided the affected portion can be exteriorized. The beginning and terminal portions of the small colon can be involved in many diseases and are not readily accessib...
Treatment of impaction colics. Impactions have been reported in the stomach and all segments of the intestine. Impactions predominately occur just oral to sites of intestinal narrowing or active pacemakers. The most common sites of impaction are in the ileum, the cecum, and the large colon pelvic flexure. The treatment of gastrointestinal impactions depends on the segment affected and the amount of bowel damage which has occurred from distension. Many impactions respond to appropriate administration of analgesics, cathartics, and oral or intravenous fluids. The prognosis for impactions treated medically is better than for t...
Colopexy. Colopexy is a surgical procedure designed to create an adhesion from the ventral colon to the body wall to prevent recurrence of large colon volvulus or displacement, and is a useful technique to prevent recurrence of this disease. Colopexies usually are reserved for broodmares, because this is the population of horses that is most predisposed to recurrence of large colon volvulus.
Lateral buccotomy for removal of a supernumerary cheek tooth in a horse. A 3-year-old female Standardbred was admitted for evaluation of a firm swelling on the right side located rostral to the facial crest and a firm intraoral swelling located rostral to the erupted cheek teeth. Examination of skull radiographs revealed a supernumerary cheek tooth rostral to the erupted third premolar. The supernumerary tooth was removed via lateral buccotomy. The horse did not have complications after surgery and resumed racing. Lateral buccotomy should be considered for removal of rostrally located maxillary or mandibular cheek teeth. Supernumerary cheek teeth can be found in lo...
Current concepts in management of abdominal adhesions. Adhesions are an important complication after abdominal surgery in horses and foals, especially after small intestinal resection and anastomosis. Prevention therapies used in horses have included nonsteroidal anti-inflammatory drugs, antibiotics, heparin, dimethyl sulfoxide, carboxymethylcellulose, and meticulous surgical technique; however, the ideal surgical technique and prevention therapy has not been determined. Further, treatment of abdominal adhesions has a poor prognosis, emphasizing the need for improvements in prevention methods.
Neodymium:yttrium-aluminum-garnet laser treatment of cystic granula iridica in horses: eight cases (1988-1996). To determine clinical features of cystic granula iridica in horses and outcome of horses treated with an ophthalmic neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. Methods: Retrospective study. Methods: 8 horses. Methods: An ophthalmic Nd:YAG laser was used to deflate cysts in all horses. Results: Horses were examined because of visual impairment (n = 5), decreased jumping performance (2), or head shaking (1). Clinical signs associated with cysts resolved in all horses after treatment. Short- and long-term complications did not develop, and cysts did not recur. Conclusions: Cystic granula ir...
Overwhelming strongyloidosis in a foal. A 6-month-old foal was evaluated because of weakness, weight loss, and inappetence of 3 weeks' duration. On initial examination, the foal was weak, poorly responsive, and emaciated. Clinicopathologic abnormalities included anemia and hypoproteinemia. Because of its severe debilitation, the foal was euthantized. Necropsy revealed marked infection of the small intestine with Strongyloides westeri and severe edema of the entire gastrointestinal tract. The foal had been orphaned when it was 6 hours old and raised in isolation from other horses. We believe that this foal developed overwhelming stro...
[Separation techniques ro achieve vital and reproduction competent equine spermatozoa populations–a survey]. Equine ejaculates are significantly characterized by widely varying parameters especially in those of practical relevance for equine Al. Therefore it is of interest for practical purposes to get subpopulations of concentrated, vital, and competent spermatozoa from the origin ejaculates. Special preparation of the donor stallions will stabilize sperm output. Fractionated semen collection from stallions supplies sperm enriched seminal fractions very useful to work with further in semen preservation. Most important to achieve a concentrated sperm subpopulation are semen manipulations post ejacula...
Adjunctive methods in equine gastrointestinal surgery. The medical management of postoperative abdominal disorders remains a diagnostic and therapeutic challenge for the equine clinician. Recent advances in the development of techniques and medications to offset or attenuate ischemia-reperfusion injury, endotoxemia, and ileus are encouraging and potentially will decrease the incidence of additional complications.
Sepsis of the common digital extensor tendon sheath secondary to hemicircumferential periosteal transection in a foal. A 4-month-old Quarter Horse was admitted for evaluation of infection that developed following bilateral hemicircumferential periosteal transection and elevation. Sepsis of the common digital extensor tendon sheath was diagnosed. Treatment included lavage of the tendon sheath, placement of an indwelling drain for lavage after surgery, establishment of drainage, and administration of antimicrobial and anti-inflammatory drugs. Three months after treatment, the foal was clinically normal.
Epidemiology of colic. Understanding the epidemiology of equine colic is directly relevant to the management of individual horses with colic. In this article, the epidemiology of colic is reviewed with emphasis on epidemiologic studies that have identified specific factors associated with increased risk of colic and epidemiologic studies that are designed to predict the need for surgery and prognosis in horses with colic. Despite the magnitude of the problem of equine colic, much remains to be learned about the epidemiology of this disease.
Surgical treatment of progressive ethmoidal hematoma aided by computed tomography in a foal. A progressive ethmoidal hematoma (PEH) was treated successfully in a 4-week-old Belgian filly by surgical removal, using a frontonasal bone flap. The filly had respiratory stridor, epistaxis, and facial enlargement over the left paranasal sinuses, which had progressively increased in size since birth. Computed tomographic images of the head obtained with the foal under general anesthesia were useful in determining the extent and nature of the soft-tissue mass and planning surgical intervention. On the basis of the histologic appearance of the mass, a diagnosis of PEH was made. Twelve months af...
Abdominal surgery in foals. Foals are good candidates for abdominal surgery because their smaller size permits a more complete abdominal exploration and frequently definitive procedures in many cases. The use of rectal examination is replaced with alternative diagnostic modalities such as barium contrast radiography and ultrasonography. With the advancements in these technologies they can distinguish common gastrointestinal lesions and, in most cases, provide sufficient information to guide surgical intervention. The unique aspects of diagnosis and surgical management of gastrointestinal disorders of the foal are discuss...
Caecal disease in equids. To review the breed, age, gender, clinical and laboratory findings, treatment and outcome of horses with caecal disease presented to a referral centre. Methods: Retrospective study of 96 cases. Methods: The breed, age, and gender of the study population were compared with the corresponding hospital population for the same period. The means (+/- SD) for clinical and laboratory findings were recorded for each caecal disorder. Treatment was categorised as medical or surgical, and outcome was recorded. Results: Caecal diseases included impaction (40% of total cases), rupture associated with concur...
[Endoparasitic fauna and incidence of species in yearling and adult horses in Upper Bavarian breeding farms with regular anthelmintic prophylaxis lasting for many years]. In this epidemiological study 127 horses from five breeding farms in Upper Bavaria were included. The horses were coproscopically examined in intervals of four weeks over a 16-month period. Since 1992 in all farms regular prophylactic treatments with anthelmintics have been carried out. In 127 horses at least five species were established, such as Parascaris equorum, Anoplocephala perfoliata, Gasterophilus intestinalis and small strongyles, whose third stage larvae were characterized by eight or twelve intestinal cells. Infections with small strongyles occurred most frequently, followed by G. ...
Age-related changes in the pharmacokinetic disposition of diazepam in foals. To evaluate changes in the pharmacokinetic disposition of diazepam in foals from 4 to 84 days of age. Methods: 4 male and 2 female full-term mixed-breed foals. Methods: Diazepam terminal half-life, volume of distribution, clearance, free fraction, unbound volume of distribution, free clearance, peak desmethyldiazepam concentration, and area under the desmethyldiazepam concentration-time curve were determined after i.v. administration of 0.25 mg of diazepam/kg of body weight to foals at 4, 21, 42, and 84 days of age. Results: Disposition of diazepam was best described using a two-compartment mo...

Surgical treatment of a comminuted articular fracture of the accessory carpal bone in a thoroughbred horse. The clinical, radiographic and ultrasonographic findings in a case of a comminuted articular fracture of the accessory carpal bone of a thoroughbred chaser are described, and its surgical treatment and aftercare are detailed. The horse made an uneventful recovery and successfully returned to racing.
Ageing draft and trotter horses by their dentition. The accuracy of ageing horses by their dentition was assessed by comparing the dental features with the known dates of birth of 212 trotter horses and 189 Belgian draft horses. The horses ranged in age from two to 25 years. In both breeds it was observed that the shedding of the incisors and the appearance of the dental stars were the most reliable features for age determination. In young animals, the dental configuration was similar in both breeds. With increasing age the incisor teeth of draft horses were more liable to abrasion than those of trotter horses. The sequential changes in appeara...
