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.
Boyle AG, Higgins JC, Durando MM, Galuppo LD, Werner JA, Decock HE.A 22-year-old female Welsh-cross pony was evaluated because of intermittent colic, signs of depression, pyrexia, anorexia, muscle wasting with abdominal distention, and weight gain over the preceding 12 months. A large abdominal mass was detected and surgically removed; the hemodynamic alterations and complications caused by the dramatic fluid losses and shifts that can occur in association with removal of a large abdominal mass required extensive postoperative management. Monitoring of clinical and hematologic variables such as attitude, heart rate, mucous membrane color, mean arterial blood ...
Senior JM, Pinchbeck GL, Dugdale AH, Clegg PD.The records of 496 orthopaedic operations on 428 horses were reviewed to estimate the prevalence of, and identify the risk factors for, the development of colic in horses after surgery. Colic was defined as any recognised sign of abdominal pain that could not be attributed to a concurrent disease. Fourteen of the horses developed colic; eight of them were undiagnosed, three were classified as impactions, one as tympanic colic of the colon, one as incarceration of the small intestine in the epiploic foramen, and one as left dorsal displacement of the colon in the nephrosplenic space. Morphine w...
Linde HJ, Kobuch R, Jayasinghe S, Reischl U, Lehn N, Kaulfuss S, Beutin L.We report the first case of a postoperative wound infection caused by Vibrio metschnikovii on the lower right leg of a patient after saphenectomy. Compared to the healing of an uninfected site, that of the right leg was delayed, and a cure was achieved by intensified wound care. Several swabs taken from the infected site grew a gram-negative rod in pure culture that was identified as V. metschnikovii by the VITEK 2 system. The source of the infection was not detected; however, the absence of putative risk factors (exposure to water or shellfish or an episode of diarrhea), the profession of the...
Fraser BS, Bladon BM.Lacerations to the digital flexor tendon sheath (DFTS) are a common injury in the horse, but little information is available in the literature regarding prognostic indicators. Objective: To ascertain whether laceration of the DFTS carried a better prognosis if treated by tenoscopic lavage, debridement and repair within 36 h of the original injury. Methods: A retrospective analysis of 39 horses treated surgically for lacerations to the DFTS was performed over a 3 year period. The injury-to-surgery interval was recorded as <36 or >36 h. The structures damaged by the injury were also recorded, as...

A hand access device (Omniport) was placed followed by 4 laparoscopic porta...
Sellon DC, Roberts MC, Blikslager AT, Ulibarri C, Papich MG.A randomized, controlled, blinded clinical trial was performed to determine whether butorphanol administered by continuous rate infusion (CRI) for 24 hours after abdominal surgery would decrease pain and surgical stress responses and improve recovery in horses. Thirty-one horses undergoing exploratory celiotomy for abdominal pain were randomly assigned to receive butorphanol CRI (13 microg/kg/h for 24 hours after surgery; treatment) or isotonic saline (control). All horses received flunixin meglumine (1.1 mg/kg IV q12h). There were no significant differences between treatment and control horse...
Bussieres M, Krohne SG, Stiles J, Townsend WM.To evaluate the efficacy of using a porcine small intestinal submucosa (SIS) graft covered by a conjunctival flap for the surgical repair of full-thickness corneal wounds in dogs, cats and horses. Methods: All records dating from August 1999 to February 2003 from Purdue University Veterinary Teaching Hospital of patients that had undergone ophthalmic surgical procedures and received a SIS corneal graft for a full-thickness lesion were reviewed. Fifteen cases were identified including six dogs, two cats and seven horses. Requirements for inclusion in this study were that SIS was used as a corne...
Mamede FV, Laus JL, Cabral VP, Vicenti FA, Barbieri-Neto J.To possibly reduce postoperative adhesions that occur after ocular myoplasties, we investigated the topical effects of 0.04% mitomycin C on the repaired areas of the medial rectus muscle using an equine renal capsule preserved in 98% glycerin for reinforcement of the sutures. Twenty-four rabbits, divided into two groups of 12 animals each [untreated (control) and treated group (MMC)], were submitted to surgical rupture of the medial rectus muscle of one eye and repair of the defect 24 h later with sutures and an equine renal capsule. Post-operative prophylactic treatment of the two groups cons...
Gemensky-Metzler AJ, Wilkie DA, Cook CS.To describe semiconductor diode laser use for anterior uveal cyst deflation and coagulation in dogs, horses and cats. Methods: The presenting clinical signs, surgical technique and postoperative results for four dogs, nine horses and seven cats with anterior uveal cysts treated with diode laser are described. Treated cysts were of sufficient size and/or number to potentially impair vision, damage the corneal endothelium, or increase intraocular pressure (IOP). One dog with free-floating cysts exhibited 'fly biting' behavior. Cysts were suspected of causing shying on the affected side and/or he...
Nixon AJ, Fortier LA, Goodrich LR, Ducharme NG.Debridement of osteochondritis dissecans (OCD) cartilage lesions results in fibrocartilage and imperfect hyaline repair tissue, and forms a permanent irregularity to the subchondral bone plate. Objective: To evaluate the clinical, radiographic and outcome effects of OCD cartilage flap reattachment for select lesions as an alternative to OCD debridement. Objective: Separated cartilage flaps resulting from OCD lesions may be re-incorporated into the hyaline cartilage surface by reattachment rather than debridement and removal. Methods: Resorbable polydioxanone pins were used to reattach OCD flap...
Durham AE, Phillips TJ, Walmsley JP, Newton JR.There is an absence of data describing the nutritional requirements and nutritional status of horses following surgery for colic; furthermore, the potential effect of parenteral nutrition (PN) on improving nutritional status in such cases is unknown. Objective: Post operative colic cases suffer from a potentially detrimental negative energy balance and the PN formulation developed in this study would lead to clinicopathologically detectable improvements in the subjects' nutritional status. Methods: Several clinicopathological variables, some known to be associated with nutritional status, were...

Story MR, Bramlage LR.Historically, there has been a consensus that conservative management of subchondral cystic lesions of the distal phalanx carries a poor prognosis. Surgical management has been advocated; however, there are no reports documenting its routine use and successful surgical treatment. Objective: To describe arthroscopically-guided curettage of distal phalangeal subchondral cystic lesions (SCLs) and report the qualitative and quantitative results in 11 affected horses age 16-33 months. Methods: Medical records of horses with previously treated lameness resulting from SCLs of the third phalanx were r...
Shoemaker R, Bailey J, Janzen E, Wilson DG.Castration is one of the most common routine surgical procedures performed in the horse, from which a number of potential complications can arise. We undertook a prospective evaluation of short-term complications associated with castration of draught colts over a 3-year period (1998-2000). Objective: To compare castration complications in a large number of draught foals with previously published literature. Methods: Five hundred and sixty-eight draught colts, age 4 or 5 months, were castrated in field conditions. Foals were observed for complications for 24 h post operatively. Results: There w...

Information retrieved from the record included breed, age, gender, discipline for whic...
Southwood LL.Horses with large colon volvulus (LCV) often require intensive postoperative medical management. Although early referral and surgical intervention are critical for minimal postoperative complications and a successful outcome, this is often not possible for many reasons. Endotoxemia, extensive mucosal damage with subsequent severe hypoproteinemia, and focal ischemic necrosis are the major causes of postoperative morbidity and mortality. Although fluid therapy, flunixin meglumine, and antimicrobials are still the mainstay of perioperative management, synthetic colloids are being used to maintain...
Cornick-Seahorn J.There is a plethora of information regarding anesthetic management of horses; however, controlled studies of the critically ill equine patient are few. These patients should be managed like any equine anesthetic candidate but much more stringently:I. Preoperative evaluation and appropriate therapy may represent the difference between life and death during the intraoperative and recovery periods. 2. The anesthetic induction and maintenance protocol should be based on the individual situation of the veterinary facility and personnel("comfort zone"). 3. Appropriate monitoring and intraoperative s...
Barakzai SZ, Johnson VS, Baird DH, Bladon B, Lane JG.There has been no objectively assessed case-control study of the efficacy of surgery to correct dorsal displacement of the soft palate (DDSP) previously reported. Objective: Composite surgery has a beneficial result on racing performance in horses affected with DDSP as compared to a matched control population. Methods: Race records were obtained for 53 racing Thoroughbreds which underwent composite staphylectomy, sternothyrohyoideus myectomy and ventriculectomy for correction of idiopathic DDSP at the University of Bristol between 1990 and 1996. Each surgical case was matched for age, sex and ...
Blazyczek I, Hamann H, Deegen E, Distl O, Ohnesorge B.Between 1994 and 2001, guttural pouch tympany was diagnosed in 51 foals; there were approximately three times as many fillies as colts, of Arabian, different German warmblood breeds and Western horse breeds. There were significantly more Arabian and paint horse foals than expected in comparison with the breed distribution of the foals hospitalised at the Clinic for Horses. The foals' breed and sex did not influence the age of onset, the type and severity of the clinical signs or the recurrence rate. A surgical laser technique was used on 50 of the foals; in 35 cases only one surgical treatment...
Jones ARE, Ragle CA, Anderson D, Scott C.To evaluate the feasibility and clinical outcomes after laparoscopic evaluation of the small intestines via laparoscopy. Methods: Prospective pilot study. Methods: Healthy adult horses (n = 5). Methods: Horses were restrained in standing stocks and received an infusion of detomidine. One port was placed in the left last intercostal space and 3 ports were placed in the right paralumbar fossa. The small intestine was run with atraumatic laparoscopic grasping forceps, from the duodenocolic plica to the ileocecal plica. Postoperative pain was scored every 4 hours for the first 48 hours. Horses...
de Moura Alonso J, de Melo-Neto GB, Dos Santos B, Mogollón García HD, Paim KP, Pinheiro Ferreira JC, Santos Schmidt EM, da Silva ANF, da Cunha GM....This study aimed to evaluate the inflammatory response of miniature horses subjected to open and half-closed orchiectomy by physical examination, blood cell count, peritoneal fluid evaluation, total plasma protein, fibrinogen, and serum amyloid A (SAA) concentrations. Methods: Thirteen male healthy miniature horses were divided into two groups, according to the surgical approach: half-closed technique (HCT) and open technique (OT). The HCT group was subjected to ligation of the spermatic cord followed by its sharp incision, and closure of the vaginal tunic, and the OT group was only submitted ...
Rigg DL, Reinertson EL, Buttrick ML.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.
Roneus B, Arnason T, Collinder E, Rasmussen M.A clinical material of 133 Standardbred horses with palmar/plantar osteochondral fragments (POF) in the metacarpo- and metatarsophalangeal joints were studied. All horses had their fragments removed with arthroscopic surgery. 102 of the horses were 3 years old or younger when surgery was performed. Anatomical localisations of the fragments were in agreement with earlier reports. There was no statistical significant difference in month of birth in the POF--group compared to the total population. Eighty % of the horses that had raced before surgery came back to racing. The racing performance rel...
Squire KR, Adams SB, Conley R.The bladder of a 750-kg Clydesdale mare had everted through the urethra into the vagina immediately after parturition. The bladder was reinverted into the peritoneal cavity by an attending veterinarian, but 4 days later, the bladder was everted again in the vagina. The mare was able to void urine through both ureters, which could be seen in the mucosal surface of the bladder. The everted bladder had become edematous and could not be reinverted through the urethra. A considerable portion of the fundus was necrotic. The mare was administered xylazine epidurally to induce perineal analgesia, and ...
Turner TA, Fessler JF.Eleven horses with rectal prolapses were examined at Purdue University. Nine of the 11 prolapses were corrected by submucosal resection. Four of those were treated by a modified submucosal resection that apposes mucosa as well as submucosa. Follow-up of 8 cases, at intervals ranging from 4 months to 6 years, established that rectal prolapse did not recur following the resection.
Scott EA.Incisional abdominal hernias in three horses were repaired, using synthetic mesh with a fascial flap overlay. The repair of large ventral abdominal hernias of horses can be accomplished by using synthetic mesh that is sutured across the defect. This material can be placed subperitoneally, retroperitoneal but subfascial, retrofascial and subfascial, or retroperitoneal but subfascial with a fascial overlay. Advantages of using this material are that it can be used for repair of large hernias, it is easy to apply, it is strong and flexible, and it is less likely to be rejected, when compared with...
Greenberg SM, Plummer CE, Brooks DE, Craft SL, Conway JA.An 8-year-old Gypsy Vanner gelding presented to the University of Florida Ophthalmology service for the evaluation of chronic, recurrent corneal ulcers behind the third eyelid of the right eye. On ophthalmic examination, a cluster of aberrant hairs was identified growing along the margin of the third eyelid. This portion of third eyelid was surgically excised, and histopathology identified the haired tissue as a dermoid. Chronic keratitis secondary to a third eyelid dermoid was diagnosed, and excision appeared curative at 6 months post-operative follow-up.
Morisset S, Hawkins JF, Frank N, Sojka JE, Berg D, Blevins WE.A 2-day-old male foal developed uroperitoneum. Initial exploration of the abdomen via ventral midline celiotomy failed to localize the source of uroperitoneum. Bilateral nephropyelocentesis and antegrade urography were performed, and a defect in the right ureter and stenosis of the left ureter were identified. With the foal in dorsal recumbency in the Trendelenburg position, ureterorrhaphy was performed on the right ureter. After ureterorrhaphy, a ureteral catheter was maintained as a stent. The stenotic left ureter was transected, and ureteroneocystostomy was performed using a drop-in mucosal...
Watts AE, Fubini SL.This report describes a modification of the parainguinal approach for removal of cystic calculi: a ventral midline laparotomy-guided parainguinal laparocystotomy. The ventral midline approach to the abdomen is rapid and routinely used by equine surgeons. With an arm introduced to the abdomen via the ventral midline, the surgeon is able to select the ideal parainguinal laparotomy incision location that allows bladder exteriorisation with the minimum amount of tension. Because the surgeon's hand is introduced via the ventral midline incision, the parainguinal incision can be sized to just allow ...
Munroe GA, Cauvin E.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.
Schneider RK, Bramlage LR, Hardy J.The distal interphalangeal joint was successfully arthrodesed in two horses using three parallel 5.5-mm cortical screws and an autogenous cancellous bone graft. The screws were directed from the palmar proximal border of the second phalanx dorso-distally across the joint space and into the third phalanx. The technique was first developed on a normal horse. The second horse, a clinical case, ruptured its deep digital flexor tendon with complete luxation of the distal interphalangeal joint. Bony fusion of the distal interphalangeal joint occurred in both horses, but both also had residual lamene...
Kuemmerle JM, Kummer M, Auer JA, Nitzl D, Fürst AE.Complicated mandibular fractures were recognised in one foal, one pony and four horses. The foal was two months old while the adult animals ranged in age from 12 to 24 years. Three horses had a unilateral horizontal ramus fracture. Two fractures were open and one was closed. Comminution was present in one of these patients while the other two horses had marked displacement of the fragments. Two suffered from comminuted fractures of the horizontal and vertical ramus of the mandible. One of these patients had open and infected fractures. One foal had a bilateral horizontal ramus fracture with ma...
Archer RM, Parsons JC, Lindsay WA, Wilson JW, Smith DF.Three pairs of longitudinal enterotomies were performed in the small colon of 10 ponies. Each pair consisted of one enterotomy through the antimesenteric band and one through the sacculation. The ponies were destroyed 96 h after surgery. The enterotomies in the two sites were compared for: speed of surgery, adhesions, bursting wall tension, neovascularisation by micro-angiography, and histological reaction. Enterotomies made through the antimesenteric band were superior because they were quicker to perform, stronger, more accurately apposed, and had less inflammation than those made through th...
Carson-Dunkerley SA, Hanson RR.To describe the short- and long-term survival rates in horses undergoing ovariectomy for granulosa cell tumors by use of the diagonal paramedian approach. Methods: Retrospective case study. Methods: 12 horses with granulosa cell tumors. Methods: A diagonal paramedian approach for unilateral ovariectomy was used for removal of each mare's granulosa cell tumor. Information about complications and outcomes was analyzed. Results: Only minimal complications were detected postoperatively when the diagonal paramedian approach was used, regardless of the preferred technique for ovarian pedicle ligatio...
Lenoir A, Perrin BRM, Lepage OM.Resection and anastomosis of small intestine during colic can lead to adhesions and recurrent colic. Several methods are available to reduce the rate of adhesions in the postoperative period, such as the use of serosal barriers. Surgical glues form a smooth surface, are fast to apply, and could reduce surgery time when performing anastomosis. A recently developed UV-polymerizable methacrylate adhesive (UV-PMA) is designed to anchor into the biological tissues' top surface offering sealant and a smooth cover over the anastomosis site. This adhesive was used ex vivo on fifteen samples of equine ...
Hogan PM, Bramlage LR, Pierce SW.A 14-year-old Thoroughbred broodmare was evaluated for signs of mild to moderate abdominal pain of 5 hours' duration. Exploratory celiotomy revealed a 20 x 8-cm subserosal hematoma associated with a focal serosal perforation overlying a muscular tear along the parietal surface of the stomach. The odor of intestinal tract gas was detected, but gross contamination of the abdomen was not evident. Concurrent partial volvulus of the small intestine was evident. Removal of the large colon from the abdomen appeared to coincide with propagation of the serosal perforation to a full-thickness gastric re...
Wagner PC, DeBowes RM, Grant BD, Kaneps AJ, Watrous BJ.Proximal growth plate fractures of the tibia in 4 foals were treated surgically. A medial approach was utilized in 3 cases and a lateral approach in the fourth. Bone screw fixation was achieved with cancellous screws and washers. In 3 cases, the screw shaft crossed the proximal tibial growth plate with no adverse effects. In all animals, there was rapid and cosmetic healing. At 8 to 18 months after surgery, all horses were sound at a walk, trot, and canter.
Scharner D, Gittel C, Winter K, Blaue D, Schedlbauer C, Vervuert I, Brehm W.Development of incisional complications following ventral median celiotomy might depend on suture pattern for skin closure. Methods: In this prospective study, 21 healthy male horses underwent celiotomy. Skin closure was either performed via a continuous percutaneous pattern (CO group; 5 warmbloods/5 ponies) or an intradermal pattern (ID group; 5 warmbloods/6 ponies). Follow-up examination of the incisional site included daily monitoring for edema, dehiscence, and drainage. Transcutaneous ultrasound was performed at Days 3, 6, and 10 as well as on Week 8 and 12 to evaluate size of edema and pr...
Harrison IW, Raker CW.Bilateral arytenoidectomy had been performed as treatment for bilateral arytenoid chondritis in 2 horses. After surgery, dorsal mucosal defects were associated with subsequent development of dorsal glottic stenosis in the 2 horses. When performing bilateral arytenoidectomy in the horse, care must be taken to eliminate dorsal mucosal defects that cross the midline. Failure to close these defects may result in glottic stenosis.
Munsterman AS, Hanson RR, Cattley RC, Barrett EJ, Albanese V.To describe a laparoscopic technique for, and short-term outcome after, closure of the epiploic foramen (EF) in horses. Methods: Descriptive, experimental study. Methods: Healthy, adult horses (n = 6). Methods: Laparoscopic portals to approach the EF were identified in standing horses. Under laparoscopic observation, the gastropancreatic fold and right lobe of the pancreas were grasped with Babcock forceps and secured to the caudate hepatic lobe using helical titanium coils to obliterate the EF. Surgical procedure time and intra- and postoperative complications were recorded. Serial analys...
Lloyd D, Walmsley JP, Greet TR, Payne RJ, Newton JR, Phillips TJ.There is little published clinical evidence on the use of a laparoscopic approach for the removal of pathologically enlarged ovaries in standing mares. Objective: To show the orders of success and complication rates that can be expected if pathologically enlarged ovaries are removed from standing, sedated mares under laparoscopic guidance using only electrosurgical means of haemostasis. Methods: A retrospective analysis was made of 55 mares in which the removal of an enlarged ovary was attempted by applying a standard laparoscopic procedure for routine ovariectomy in standing mares including a...
Adams SB.A fractured right supraglenoid tubercle in a 15-month-old Thoroughbred gelding was repaired by partial biceps brachii tenotomy, interfragmentary compression, and tension band wiring. The horse is currently being ridden daily and has remained sound for 4 years.
Nelson AM.Of 275 mares receiving prostaglandin F2alpha-Tham salt for its luteolytic effect upon the corpus luteum, 231 (84 per cent) exhibited signs of oestrus (range 73-95 per cent). Some mares not exhibiting overt oestrus may, nevertheless, ovulate and post-treatment rectal palpation of mares apparently failing to respond is suggested in these cases. Of 210 mares for which subsequent history was available. 104 (49.5 per cent) became pregnant from breeding at the post-treatment oestrus that immediately followed the induced regression of the corpus luteum (range 42.2-55.5 per cent). Fertility is compara...
Hawkins JF, Frank N, Sojka JE, Levy M.Two horses with chronic empyema of the auditory tube diverticulum (guttural pouch) were refractory to medical treatment; empyema was bilateral in 1 horse and unilateral in the other. Both horses were treated by fistulation of the cartilage of the pharyngeal orifice by use of a neodymium:yttrium-aluminum-garnet laser in a noncontact manner. To maintain patency of the fistulae, indwelling catheters were placed into the openings created by the laser. For both horses, long-term follow-up did not reveal complications, and both owners were satisfied with results of the procedure. The authors recomme...
Moser DK, Schoonover MJ, Sippel KM, Dieterly AM, Ritchey JW, Wall CR.This report describes fibrous cyst lining injection and extracorporeal shock wave therapy (ESWT) of a medial femoral condyle (MFC) subchondral cystic lesion (SCL) resulting in catastrophic MFC fracture in an Arabian mare. The mare was presented for evaluation of a severe hind limb lameness of approximately 4 months duration. On presentation, a non-weight bearing lameness of the left hind limb with severe effusion and soft tissue swelling of the stifle region was noted. Radiographic evaluation of the stifle revealed a large SCL of the MFC with associated osteoarthritis. Arthroscopic guided intr...
Russell T, Wainscott M.Twenty-seven horses were treated for epiglottic entrapment by using an oral, hand-assisted bistoury knife technique, under general anaesthesia; 26 of them returned successfully to racing, but one developed a permanently displaced soft palate. After the surgery 13 of the horses had an increased handicap rating and 13 had a decreased rating.
Tate LP, Fogle CA, Bailey CS, Tate KB, Davis JW.To describe a technique for ovariectomy through a colpotomy using a chain écraseur with laparoscopic guidance and report outcome in 4 mares. Methods: Case series. Methods: After insertion of a laparoscope into the abdomen through the left flank, colpotomy was performed to allow introduction of an écraseur into the caudal aspect of the abdomen. Grasping and removal of the ovary and evaluation of the pedicle was observed via the laparoscope. The laparoscope was then inserted in the right flank for right ovariectomy. The colpotomy was closed in a continuous suture pattern using laparoscopic or ...
Bramlage LR, Hanes GE.A 3-year-old Thoroughbred mare was examined because of hindlimb lameness from incomplete fracture of the tibia, which became a complete diaphyseal fracture during the examination. The fracture was repaired by open reduction and internal fixation with lag screws and 2 neutralization plates.
