The post-operative period in horses refers to the timeframe following surgical procedures during which the animal undergoes recovery and rehabilitation. This period involves careful monitoring and management to ensure proper healing and to minimize complications. Key aspects of the post-operative period include pain management, wound care, and the prevention of infections. Horses may require restricted movement, dietary adjustments, and regular veterinary evaluations to assess recovery progress. This page compiles peer-reviewed research studies and scholarly articles that explore the management strategies, physiological responses, and outcomes associated with the post-operative period in equine patients.
Eight mares with third-degree rectovestibular lacerations were treated by a two-stage surgical technique. The rectovestibular shelf was corrected with three parallel 'circular' continuous suture rows distributed along the longitudinal axis of the vagina, and the perineal body was reconstructed with three divergent simple continuous rows. Primary healing of the first-stage surgery occurred in all the mares. Seven of the mares completed the two-stage surgery and primary healing occurred in all of them. One of them returned to endurance racing competition and one was lost to follow-up. The other ...
A 4-month-old Thoroughbred filly presented for abdominal pain was diagnosed with a T-shaped malformation of the ventral colon at exploratory laparotomy. Following resection and anastomosis of the large colon, no further episodes of abdominal pain occurred during a 12-month follow-up. Acute dehiscence of the linea alba occurred as a complication of the initial laparotomy, but was successfully managed following additional surgical repair. T-shaped malformation of the ventral colon has not previously been reported and is considered a congenital malformation of mesocolon formation.
Within the veterinary world, data regarding the surgical management of hypospadias is lacking. Reports within equines have documented resective phallectomy procedures rather than urethral reconstruction. This case report documents the first ever urethroplasty for an equine hypospadias, performed by a consultant paediatric surgeon. The urethroplasty was achieved by applying the same surgical principles mastered from paediatric urology to a horse. The indication for surgery was contact dermatitis of the hind-leg, which impaired the thoroughbred foal's racing potential. Methods: A single stage ur...
Many colic horses are compromised due to the disease state and from hours of starvation and sometimes long trailer rides. This could influence their muscle energy reserves and affect the horses' ability to recover. The principal aim was to follow metabolic parameter before, during, and up to 7 days after anaesthesia in healthy horses and in horses undergoing abdominal surgery due to colic. Methods: 20 healthy horses given anaesthesia alone and 20 colic horses subjected to emergency abdominal surgery were anaesthetised for a mean of 228 minutes and 183 minutes respectively. Blood for analysis o...
Initial treatment of colic is aimed at maintaining hydration and acid-base balance, controlling pain and reestablishing peristalsis. A poor response to medical treatment in the first 12-18 hours suggests the need for laparotomy. Other indications for surgery include: rising pulse rate, exceeding 60/minute for several hours; congested mucosae; delayed capillary refill; silent abdomen; gastric reflux; distended or displaced loops of bowel on rectal examination; intractable pain; and adverse laboratory findings. Postoperative care should consist of hand-walking for 30 days, followed by confinemen...
The objective of this study was to compare effects of butorphanol (BUT) or buprenorphine (BUP), in combination with detomidine and diazepam, on the sedation quality, surgical conditions, and postoperative pain control after cheek tooth extraction in horses, randomly allocated to 2 treatment groups (BUT: = 20; BUP: = 20). A bolus of detomidine (15 μg/kg, IV) was followed by either BUP (7.5 μg/kg, IV) or BUT (0.05 mg/kg, IV). After 20 min, diazepam (0.01 mg/kg, IV) was administered and sedation was maintained with a detomidine IV infusion (20 μg/kg/h), with rate adjusted based on scores to ...

Albrecht M, MacGillivray KC, Juez B, Freeland R.A 4.5-month-old Standardbred colt presented for neck swelling and fever. Endoscopy and contrast radiography identified a full thickness esophageal perforation. Surgical intervention with fasciotomies and placement of an esophageal feeding tube was elected. Intensive postoperative treatment was carried out with broad-spectrum antibiotics, gastroprotectants and probiotics, calculated feeding plan, esophagostomy and fasciotomy site lavages, care, and cleaning. Complications included recurrent bilateral pneumothorax and development of an incomplete fistula at the esophagostomy site following remov...
Willette J, Guinn A, Munsterman A.Impactions of the jejunum are rarely described in the literature. The current case series describes six cases of adult horses with jejunal impactions with feed material diagnosed by exploratory celiotomy. Horses underwent exploratory celiotomy based off of their degree of pain despite medical management and concerns for a primary strangulating small intestinal lesion. All jejunal impactions were relieved via manual decompression of the impaction into the cecum. None of the cases underwent a resection or anastomosis at the site of impaction. All horses were treated with gastroprotectants (omepr...
Gandini M, Bertone C, Giusto G.Castration remains a common surgical procedure in equids, yet postoperative complications such as hemorrhage, infection, and eventration persist, influencing surgical outcomes. This retrospective study introduced a novel modified semi-closed castration technique aimed at minimizing these complications. Eighty-five sexually intact mature male equids (including horses, ponies, and donkeys) underwent the described inguinal castration procedure under general anesthesia. The technique involved a carefully managed opening and subsequent secure closure of the parietal vaginal tunic, enabling direct i...
Muñoz AM, Cribb N.Minimally invasive laparoscopic surgical techniques are desirable in horses and other equids. A new approach called "modified single incision laparoscopic surgery (SILS) for equine cryptorchidectomy" is described, along with the postoperative outcomes of 10 equids. A SILS Port device (Covidien) was placed a 30- to 40-millimeter incision in combination with 1 or 2 15-millimeter para-inguinal incisions to exteriorize the intra-abdominal testicles. Ten animals, 2 bilateral abdominal cryptorchid horses and 8 unilateral abdominal cryptorchid equids, underwent cryptorchidectomy using the SILS tech...
Sharshar A, Hammad A, Salem M, El-Sunsafty M.This study was carried out to evaluate a rectal pull-back one-stage technique, which is a modification of the one-stage Goetz technique, for treating third-degree perineal laceration or rectovestibular fistula. Methods: This study was performed on 12 mares, ten of whom suffered from third-grade perineal laceration, and two suffered from rectovestibular fistula and were included in this study. After incision of the vestibular shelf horizontally, the dissected rectal flap was pulled caudally and sutured to the anal sphincter during its reconstruction at the final stage. While the vestibular shel...
Samsel J, Gündemir O, Szara T, Witkowski M.Uterine torsion in mares belongs to maternal pregnancy disorders, accounting for 5-10% of complications in the last trimester of pregnancy. Two surgical techniques for repositioning uterine torsion are used: flank laparotomy in local anesthesia on a standing mare (SFL) and midline laparotomy carried out under general anesthesia (MI). The study aims to present the exact protocol used by the authors to qualify a mare with uterine torsion for surgery using one of the above-mentioned methods.A total of 19 mares were operated on, of which 13 underwent midline laparotomy under general anesthesia, an...
