Objective—To evaluate efficacy of debridement for
treatment of supraspinous bursitis in horses and to
evaluate the outcome.
Animals—10 horses with clinical signs of supraspinous
Procedure—Medical records were reviewed for signalment,
anamnesis, results of physical and radiographic
examination, microbial culture results of
supraspinous bursa tissue or exudate, Brucella abortustiters,
type of antimicrobial and anti-inflammatory
therapies, surgical technique, complications of the
surgical procedure, and findings on histologic examination
of excised nuchal ligament and bursal tissue.
Telephone follow-up with owners, trainers, or referring
veterinarians was performed.
Results—The described surgical technique was
effective in resolving drainage from the
supraspinous bursal region in 5 of 6 horses available
for long-term follow-up. The most common complication
following surgery was the development of
purulent wound drainage. Two horses required multiple
surgeries to resolve clinical signs of
supraspinous bursitis. The most common organism
isolated from the supraspinous bursa was β-
hemolytic Streptococcus spp. All horses were discharged
from the hospital and long-term follow-up
was available for 6 horses. All 6 horses could be
used for their intended use.
Conclusion and Clinical Relevance—Debridement
in standing horses is an effective method of resolving
clinical signs of supraspinous bursitis. (J Am Vet Med
Objective—To evaluate the management of equids undergoing cryptorchidectomy at a referral hospital.
Design—Retrospective case series.
Animals—604 client-owned equids.
Procedures—Medical records of all equids undergoing surgical treatment of cryptorchidism from 1977 to 2010 were retrospectively reviewed. Analyses of breed, location of retained testes, accuracy of palpation per rectum for determining the location of retained testes, surgical technique, and postoperative complications were performed.
Results—The most frequently affected breed was the Quarter Horse (282/604 [47%]), which was significantly overrepresented. Of the 604 equids, 90 (15%) had undergone previous surgical attempts at castration. Preoperative palpation per rectum was performed in 395/604 (65.4%) patients, and was accurate in predicting the location of the retained testes in 354/395 (89.6%). Surgeons were significantly more likely to be incorrect in determining the location of the retained testis by means of palpation per rectum in patients that had undergone a prior attempt at castration. For equids with abdominal cryptorchidism (360/604 [59.6%]), the most common surgical technique was noninvasive cryptorchidectomy (298/360 [82.8%]). In unilateral cryptorchids (521/604 [86.3%]), the 2 most common sites were left abdominal (184/521 [35.3%]) and right inguinal (148/521 [28.4%]). For bilateral retention (80/604 [13.2%]), abdominal cryptorchidism was most common (48/80 [60%]). Fever was present in 138/324 (43%) equids on the first day after surgery. Postoperative fever was not significantly associated with any variables evaluated. Including postoperative (≤ 24 hours) fever, 150 of 604 (25%) patients developed postoperative complications. Excluding postoperative fever, 18 of 604 (3%) patients developed major postoperative complications; complications in 10 of 604 patients were deemed surgically related, and 3 of 604 patients died.
Conclusions and Clinical Relevance—Results indicated that cryptorchidectomy in equids performed with a variety of surgical approaches was associated with minimal postoperative complications. A history of previous attempts at castration decreased the ability to accurately predict the location of the retained testis.
Objective—To determine outcome of horses in
which cutaneous masses were removed with a carbon
Procedure—Medical records of horses with 1 or
more cutaneous masses treated with a carbon dioxide
laser were examined. Follow-up information was
obtained through telephone interviews with owners
and referring veterinarians.
Results—Cutaneous masses were classified as sarcoids
(15 horses), neoplastic masses other than sarcoids
(squamous cell carcinoma ; fibroma ; and
melanoma ), and nonneoplastic masses (6).
Minimum follow-up time was 6 months. Five sarcoids
and 2 squamous cell carcinomas recurred. Seven
(21%) horses had complications associated with
dehiscence of wounds that had been closed primarily
or failure of wound healing because of recurrence of
the mass. Twenty-six (81%) owners were satisfied
with the cosmetic appearance following surgery.
Conclusion and Clinical Relevance—Results suggest
that a carbon dioxide laser may be effective for
treatment of cutaneous masses in horses. (J Am

Objective—To determine whether heavy (≥ 680 kg [≥ 1,500 lb]) draft horses undergoing surgical treatment for acute signs of abdominal pain were at a greater risk for anesthetic and postoperative complications and lower postoperative survival rates than light (< 680 kg) draft horses.
Design—Retrospective case series.
Animals—72 draft horses.
Procedures—Medical records of draft horses that underwent exploratory celiotomy for signs of acute abdominal pain from October 1983 to December 2002 were reviewed. Medical records of draft horses in which a celiotomy was performed for correction of reproductive abnormalities were not included in the study.
Results—When compared with light draft horses, heavy draft horses had longer durations of anesthesia, more postoperative complications, and lower survival rates. Seventy-six percent of horses that recovered from anesthesia had postoperative complications. Postoperative complications associated with low survival rates included myopathy and neuropathy, ileus, diarrhea, and endotoxemia. All horses with postoperative myopathy and neuropathy died or were euthanized. The short-term survival rate for horses that recovered from anesthesia was 60%. Horses undergoing small intestinal surgery had a worse prognosis for short-term survival than those undergoing large intestinal surgery. The survival rate for horses for which long-term (> 1 year) follow-up information was available was 50%.
Conclusions and Clinical Relevance—Draft horses weighing > 680 kg that underwent surgery because of acute signs of abdominal pain had longer durations of anesthesia, more postoperative complications, and higher mortality rates than draft horses weighing < 680 kg.
