The effects of extracorporeal shock-wave therapy on the ultrasonographic and histologic appearance of collagenase-induced equine forelimb suspensory ligament desmitis.

Extracorporeal shock-wave therapy (ESWT) may stimulate healing of desmitis in multiple species. The objective of this study was to evaluate the ultrasonographic and histologic appearance of collagenase-induced suspensory ligament (SUL) desmitis in untreated ligaments and ligaments treated with ESWT in horses. Four mature horses had SUL desmitis induced in both forelimbs. Beginning 3 weeks after induction of the lesions, one ligament per horse was treated 3 times at 3-week intervals with ESWT. The percent lesion, echogenicity and fiber alignment scores of the SULs were evaluated at 3-week intervals for a total of 15 weeks. At the completion of the study, the horses were euthanized and the SULs collected, fixed and processed for histopathologic evaluation. Ultrasonography showed treated SULs had a smaller percent lesion at the maximal injury zone (p = 0.001), and the total percent lesion (p = 0.01), total fiber alignment score (p = 0.0167) and total echogenicity (p = 0.0023) were all smaller in the treated ligaments. The fiber alignment score and echogenicity were not statistically different at the maximal injury zone. The treated SULs had a more concentrated area of metachromasia associated with healing than the untreated ligaments, where metachromasia appeared more diffuse throughout the ligament. ESWT improved the rate of healing as assessed ultrasonographically.

Nonsurgical treatment of uterine torsion in seven mares.

Nonsurgical correction of uterine torsion was performed in 7 mares, and 6 foals were subsequently born alive. Uterine rupture necessitated euthanasia in 1 mare. Correction was achieved by rolling of the mares after general anesthesia had been induced. Previously, this technique was believed to be associated with a high prevalence of fetal and maternal mortality. Nonsurgical correction may be a satisfactory alternative to abdominal surgery in treating uterine torsion in mares.

Marsupialization of an abdominal abscess caused by Serratia marcescens in a mare.

An intra-abdominal abscess was diagnosed in a 7-year-old mare by palpation per rectum and from abnormal clinicopathologic findings. Initial treatment with procaine penicillin for 21 days was unsuccessful in halting the deterioration of the physical condition of the mare. Surgical exploration of the abdomen revealed a mass in the wall of the left ventral colon. Drainage was achieved by marsupialization. Serratia marcescens was isolated from the abscess. Recovery appeared complete, and the mare has resumed broodmare capability.

Tracheal compression secondary to abscessation of cranial mediastinal lymph nodes in a horse.

Respiratory distress and laryngeal paralysis were found to be caused by a Streptococcus equi abscess of cranial mediastinal lymph nodes, putting pressure on the trachea at the thoracic inlet. Surgical drainage was required to relieve the compression, and long-term antibiotic therapy was used to treat the bacterial infection. The trachea returned to normal diameter but left laryngeal hemiplegia persisted. Peritracheal abscesses should be considered in the differential diagnosis of inspiratory dyspnea of the horse.

Sand-induced diarrhea in a foal.

A diagnosis of sand enteropathy was made in a 3 1/2-month-old Quarter Horse filly. Clinical signs included diarrhea and weight loss of 2 1/2 months' duration. Abdominal radiographs were useful in diagnosis of the condition and in evaluating response to therapy. The filly responded to treatment with psyllium hydrophilic mucilloid although full recovery took 2 months. Diagnosis and treatment of sand enteropathy is discussed.

Comparison of three techniques for intestinal anastomosis in Equidae.

Thirteen horses and ponies were used to evaluate an anastomotic technique utilizing a modified Gambee suture pattern. The modified Gambee technique was compared with a single-row everting technique and a double-row inverting technique. The double-row inverting technique predisposed to intestinal obstruction and resulted in minimal adhesions. The everting technique predisposed to leakage of intestinal contents and subsequent peritonitis. Adhesions were formed at the site of the anastomosis to such an extent as to jeopardize the proper position of the bowel. The technique did not cause any luminal constriction initially, but the ensuing adhesions did tend to limit the expansibility of the bowel. The modified Gambee technique was associated with minimal constriction of the bowel lumen. Excessive adhesions and leakage were not found to be problems associated with the technique. It was concluded that, in Equidae, the modified Gambee technique for intestinal anastomosis results in near normal lumen diameter, minimal adhesions, and adequate strength, thus being safe and effective.

A modified parainguinal approach for cryptorchidectomy in horses. An evaluation in 107 horses.

A modified parainguinal approach was used to castrate 119 abdominal cryptorchid horses. The operative time ranged from 10 to 30 minutes. Follow-up information was obtained for 107 horses. Swelling, more severe than that expected in routine castrations, was reported in six horses. An incisional abscess had to be drained in one horse and one horse died of unexplained causes 3 days after the surgery.

A technique for elective splenectomy of equidae using a transthoracic approach.

Splenectomy was performed electively on 80 ponies, horses, and donkeys for preparation in collecting Babesia antigens. Access to the abdomen was by resection of the sixteenth left rib and incision of the diaphragm. The technique afforded good exposure of the splenic vessels and attachments. Closure was facilitated by preservation of the periosteum of the resected rib. Difficulty was encountered both in surgical technique and postoperative complications in obese animals. The transthoracic approach was found to be a useful technique for equine splenectomy.
