Topic:Surgery
Surgery for horses encompasses a range of procedures performed to diagnose, treat, or manage various medical conditions. These procedures may involve soft tissue or orthopedic interventions and require specialized techniques to accommodate the unique anatomical and physiological characteristics of equines. Common surgical procedures in horses include colic surgery, fracture repair, and arthroscopy. The success of equine surgery depends on numerous factors, including the type of procedure, the horse's overall health, and post-operative care. This page compiles peer-reviewed research studies and scholarly articles that explore surgical techniques, outcomes, and advancements in equine surgical practices.
Changes in coagulation and markers of fibrinolysis in horses undergoing colic surgery. Activation of coagulation can be frequently found in horses with colic. However, it has also been demonstrated as a sequela of surgical trauma alone in humans. The purpose of the present study was to determine changes in coagulation and fibrinolysis in horses that underwent colic surgery and to evaluate whether these changes were secondary to the colic or the surgery and wound healing. Thirty horses that underwent colic surgery with uncomplicated recovery were included. Ten horses with a Forssell's procedure served as control group with a standardized surgical trauma. Besides daily physical ex...
[Clinical treatment of equestrian injuries in Groningen, 1990-1998: serious long-term effects]. To determine whether equestrian injuries result in long-term residual symptoms and to establish the risk factors for these outcomes. Methods: Retrospective, descriptive. Methods: A total of 88 patients older than 17 years of age who had been admitted to the Department of Surgery, University Hospital Groningen during the period 1990-1998 because of an equestrian injury were included in the study. After an average period of five years an inventory was made using the Sickness Impact Profile 68 (SIP68), if absenteeism from work or sport and disabilities or handicaps were experienced. Following thi...
Pancreatic injury in equine acute abdomen evaluated by plasma trypsin activity and histopathology of pancreatic tissue. In cases of equine acute abdominal disease, where pancreatic damage is suspected, pancreatic damage can be assessed by measuring increased trypsin activity in the plasma of horses suffering intestinal obstruction and severe shock. The pancreas is particularly vulnerable to splanchnic hypoperfusion because it is a highly active tissue. In this study, 10 horses undergoing abdominal surgery for intestinal obstruction were assayed for trypsin activity on admission and, because of extensive intestinal lesions that were not amenable to surgery, euthanasia was selected; the pancreas was removed befor...
Percutaneous puncture technique for treating persistent retropharyngeal lymph node infections in seven horses. Between 1999 and 2001, seven horses with fever, dysphagia and a history of chronic upper respiratory tract infection lasting between three weeks and three months were examined. They had been treated unsuccessfully with a variety of antibiotics for three to four weeks. A deep abscess in a retropharyngeal lymph node was diagnosed in each case by clinical examination, endoscopy and echographic examination of the retropharyngeal region. The infected retropharyngeal lymph node of each horse was punctured with a spinal needle under ultrasound guidance. Pus was aspirated from four of the horses, and ...
Use of a hydroxyapatite orbital implant in a cosmetic corneoscleral prosthesis after enucleation in a horse. A hydroxyapatite orbital implant was used after enucleation of an eye from a 5-year-old performance horse. A custom-made corneoscleral prosthesis was made and fitted over the hydroxyapatite implant. The implant and surgery were well tolerated. Placement of a cosmetic prosthesis is desired after enucleation of equine eyes to allow horses to return to competition. Synthetic spheres consisting of methylmethacrylate or silicone have been used, although reported complications have included extrusion, infection, and poor cosmetic results. Hydroxyapatite orbital implants made from marine coral allow ...
Diagnosis of a uterine leiomyoma using hysteroscopy and a partial ovariohysterectomy in a mare. A 14-year-old quarter horse mare had a 2-year history of infertility and the presence of a mass in the right uterine horn. Prior to surgery, the mass was determined to be invasive by using ultrasonography and hysteroscopy. A partial ovariohysterectomy was performed. The mass was diagnosed histologically as a uterine leiomyoma.
Diagnostic decision rule for support in clinical assessment of the need for surgical intervention in horses with acute abdominal pain. A prospective survey of horses with colic referred to a university hospital was undertaken to elaborate on a simple clinical decision support system capable of predicting whether or not horses require surgical intervention. Cases were classified as requiring surgical intervention or not on the basis of intraoperative findings or necropsy reports. Logistic regression analysis was applied to identify predictors with the strongest association with treatment needed. The classification and regression tree (CART) methodology was used to combine the variables in a simple classification system. The pe...
Use of an active intra-abdominal drain in 67 horses. To describe the insertion technique, efficacy, and complications associated with the use of an active (closed-suction) abdominal drain in horses. Methods: Retrospective study. Animals-Sixty-seven horses with abdominal contamination treated by abdominal lavage and use of a closed-suction abdominal drain. Methods: Medical records of horses (1989-1996) that had a closed-suction abdominal drain were reviewed. Follow-up information was obtained by telephone interviews with owners. Results: Sixty-eight closed-suction abdominal drains were used in 67 horses that had abdominal contamination, peritonit...
Evaluation of the field application of PCR in the eradication of contagious equine metritis from Japan. The effectiveness of the polymerase chain reaction (PCR) as a field application test for the eradication of contagious equine metritis (CEM) was evaluated. Seven-thousands five-hundred and thirty-four genital swabs were collected from 4,026 Thoroughbred broodmares and stallions in Japan to test "high risk" horses as well as for general surveillance testing from 1998 to 2001. Bacterial isolation as well as PCR testing of original specimens and cultured specimens was performed for detection of Taylorella equigenitalis from genital swabs. As a result, T. equigenitalis was detected in 12 mares and...
Laparoscopic repair of ruptured urinary bladder in a stallion. A 12-year-old stallion was evaluated because of pollakiuria; endoscopy of the urinary tract during general anesthesia revealed that the urinary bladder was intact. After recovery, the stallion developed clinical and biochemical signs of bladder rupture, which was confirmed by endoscopy. Cystoplasty in adult stallions represents a unique surgical dilemma; the large distance between the incision site and the bladder necessitates the repair be accomplished under maximum tension with minimal exposure. Because traditional surgical approaches through ventral midline or paramedian incisions provide l...
Surgical management of urolithiasis. The surgical management of urinary calculus disease has changed dramatically in the past two decades. Minimally invasive options have made open stone surgery nearly obsolete. The development of shock wave lithotripsy, percutaneous nephrostolithotomy techniques and intracorporeal lithotripsy devices has conferred unprecedented management tools for upper tract stones. Moreover, transfusion rates, hospital costs, and convalescence periods have been markedly reduced when compared to open surgery. Likewise, the advent of fiberoptic technology has resulted in miniaturization of ureteroscopes making ...
[Colic surgery in the horse: a retrospective study of 272 patients]. In the period from January 1995 until December 2000, 272 horses underwent a laparotomy for gastrointestinal disorders. The results of these surgeries were evaluated. From these 272 patients 176 (= 65%) were discharged in good health from the hospital. When the patients that were euthanized immediately after the start of the surgery, because of a fatal deterioration, were not taken into account, the short time survival rate was 77%. Strangulated small and large intestinal obstructions (48%) had a lower short time survival rate than non-strangulated obstructions (87%). Fatal postoperative compli...
[Initial management of congenital varus equinus clubfoot by Ponseti’s method]. The choice of first-line treatment for congenital varus equine clubfoot remains a controversial issue largely dependent on experience. In France, functional treatment predominates. In 1948, Ponseti proposed reducing the deformity with successive casts. Although cast treatment is a very old method, Ponseti's method is original because it is based on strict rules established from anatomic evidence. The goal is not to correct the apparent deformation, but on the contrary to impose a simultaneous supination and abduction of the foot. Once the calcaneopedal block has been derotated, percutaneous te...
Implantation of a dual-chamber, rate-adaptive pacemaker in a horse with suspected sick sinus syndrome. A five-year-old gelding suffered syncope at the end of a period of exercise. A 24-hour electrocardiogram recording revealed intermittent pauses in the sinus rhythm of up to 10 seconds, indicating sinus node disease; the pauses occurred repeatedly, particularly after exercise. A dual-chamber, rate-adaptive pacemaker was successfully implanted, which prevented excessive postexercise bradycardia and syncope, and allowed the horse to return to work.

Use of a condylar screw plate for repair of a Salter-Harris type-III fracture of the femur in a 2-year-old horse. A 2-year-old sexually intact male Paint horse weighing 427 kg (940 lb) was admitted for examination and treatment of intermittent non-weight-bearing lameness of the right hind limb of 1 week's duration. Radiography revealed a displaced Salter-Harris type-III fracture of the right femoral condyle with the sagittal component of the fracture line located in the intercondylar space and the transverse component exiting on the medial aspect of the femur. The fracture was repaired with a condylar screw plate designed for repair of femoral condylar fractures in humans. The owner reported by telephone ...
[Endoscopic lithotripsy of a urinary bladder calculus with the aid of a holmium-YAG-laser in a gelding]. A 6 year old Haflinger gelding was presented to the reporting clinics with a history of chronic dysuria. A large cystic calculus (12 x 9 x 9 cm) was diagnosed cystoscopically. Lithotripsy was carried out endoscopically in the standing, sedated patient with a Holmium:YAG surgical laser (2100 nm, 0.5-3.5 J/pulse, 3-60 pulses/sec.). The endoscope was inserted into the bladder via perineal urethrostomy. Fragmentation of the urolith was carried out with a laser fiber (core diameter 600 microns) in contact mode. Healing proceeded uneventfully. On follow up examination 8 weeks post surgery, no signs ...
Infusion of guaifenesin, ketamine, and medetomidine in combination with inhalation of sevoflurane versus inhalation of sevoflurane alone for anesthesia of horses.

Factors associated with development of ileal impaction in horses with surgical colic: 78 cases (1986-2000). Deal impaction is prevalent in the south-eastern USA, where feeding of Coastal Bermuda hay has been implicated as a risk factor. Alternatively, infection with the tapeworm Anoplocephala perfoliata has been identified as a risk factor for ileal impaction in the UK. We hypothesised that feeding Coastal Bermuda hay and failure to administer routinely an anthelmintic with efficacy against tapeworms would place horses at risk of developing ileal impaction in the USA. Seventy-eight horses, with surgically confirmed ileal impaction and 100 horses admitted for colic that did not have an ileal impactio...
