Hernias in horses refer to the abnormal protrusion of an organ or tissue through a defect or opening in the surrounding muscle or connective tissue. They can occur in various forms, including umbilical, inguinal, and diaphragmatic hernias, each with distinct anatomical locations and characteristics. Umbilical hernias are often congenital, appearing near the navel, while inguinal hernias involve the groin area and can affect the intestines or reproductive organs. Diaphragmatic hernias involve the diaphragm and may impact respiratory function. The condition can arise due to congenital defects, trauma, or increased abdominal pressure. This page compiles peer-reviewed research studies and scholarly articles that explore the etiology, diagnosis, treatment options, and outcomes of hernias in equine species.
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...
van der Velden MA, van der Harst MR.A literature review is given concerning the occurrence, clinical signs and possible treatment of the different types of inguinal herniation in foals. A six-week old filly with a reducible inguinal hernia is described in detail.
Voermans M, Butler CM, van der Velden MA, Sloet van Oldruitenborgh-Oosterbaan MM.Umbilical hernias are common in foals. This article provides a review of the literature and presents a case of an 1.5-year-old Friesian mare with an incarcerated umbilical hernia. After reposition of the incarcerated intestine (with a lot of effort), the practising veterinarian referred the mare to the Department of Equine Sciences. Preperforative peritonitis was diagnosed, presumed to be caused by necrotic bowel. After laparotomy, this tentative diagnosis was confirmed. The necrotic part of the small intestine was resected and intensive medical treatment was started. Initially, the mare recov...
Schambourg MA, Laverty S, Mullim S, Fogarty UM, Halley J.Thoracic trauma occurs in newborn foals and may cause associated clinical signs; this condition remains poorly documented. Objective: The purpose of this study was to describe the pathological features of thoracic trauma in newborn foals presented for necropsy examination between 1990 and 2000. Methods: Necropsy reports of foals with thoracic trauma from 1990-2000 were reviewed. Subject details, clinical signs, thoracic and abdominal lesions were noted and analysed statistically. Results: Sixty-seven (9%) of 760 necropsied foals had thoracic trauma. In 19 foals, fractured ribs were considered ...
Wiemer P, Bergman HJ, van der Veen H, Pruissen L.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...
Malone ED, Farnsworth K, Lennox T, Tomlinson J, Sage AM.To describe the surgical treatment of a dorsal diaphragmatic hernia in an adult horse using thoracic rib resection aided by thoracoscopy and a flank incision. Methods: Case report. Methods: One client-owned horse. Results: A six-year-old Dutch warmblood gelding was admitted for colic-associated colonic incarceration in a diaphragmatic hernia. Seven weeks after the initial colic surgery, the gelding underwent surgery to repair the defect. Thoracoscopy and a flank incision were used to identify the location of the hernia and the subsequent site of rib resection. The stomach was adhered to the ed...
Mariën T.Standing laparoscopic herniorrhaphy was performed in 9 stallions. Appropriate analgesia was achieved by sedation with detomidine and local flank infiltration with mepivacaine. Three portal sites at the paralumbar fossa were used to perform the herniorrhaphy by means of triangulation. A cylindrical polypropylene mesh was inserted and fixated in the inguinal canal. Subsequent adhesion formation resulted in an obliterated inguinal canal within 2 weeks. This minimal invasive technique allowed us to perform a testis sparing herniorrhaphy in the standing horse.
Gayle JM, Macharg MA, Smallwood JE.To report the clinical and surgical findings and outcome for horses with strangulating obstruction caused by herniation through the proximal aspect of the cecocolic fold. Methods: Retrospective study. Methods: Nine horses. Methods: Medical records were reviewed for clinical signs, surgical findings and technique, and outcome. Cadaver ponies and necropsy specimens were also used to study the regional anatomy of the cecocolic fold. Results: The ileum and distal jejunum were strangulated in 8 horses, whereas in 1 horse the small intestine and the left ascending colons were incarcerated in a rent ...
Enzerink E, van Weeren PR, van der Velden MA.The closure of the body wall defect at the umbilicus was studied in relation to the development of umbilical hernias in a group of 44 normal foals, 25 of which were followed from birth until five months of age, and 19 from birth until 11 months of age. At birth, 19 of the foals had a defect in the body wall at the umbilicus that was termed a 'palpable umbilical ring'. In 18 of them this defect disappeared within four days, but in the other the ring did not close and a hernial sac with abdominal contents was palpable. This foal was considered to be the only foal to have a truly congenital umbil...
Steinman A, Kelmer G, Avni G, Johnston DE.An omphalocele was detected at birth in a male Arabian foal. The mass contained small intestine and after releasing a constricting band at the body wall, the contents slipped easily back into the abdomen. On the outside was the hairless pink membrane. The interior, now empty of small intestine, contained the umbilical arteries and vein, and a large urachus that extended from the bladder to the opening at the extremity of the mass. Six days after corrective surgery the foal was sent home and remained healthy.
Dabareiner RM, White NA.A 9-year-old Thoroughbred was evaluated for clinical signs of acute abdominal pain. During laparotomy, a rent in the diaphragm and herniation of the small intestine into the thoracic cavity were detected. Because edges of the rent were smooth and fibrous, which suggested the defect was chronic, the abdomen was closed without repairing the rent. After recurrence of clinical signs, a second laparotomy was performed, during which the intestines were found to have reherniated. The diaphragmatic rent was repaired, using a polypropylene mesh secured with stainless steel staples. The horse recovered ...
Hammock PD, Freeman DE, Magid JH, Foreman JH.A 12-year old 573-kg (1,261-lb) Quarter Horse gelding was referred with colic of 12 hours' duration and with poor response to medical treatment. On the basis of physical and laboratory findings, a pelvic flexure impaction was suspected. The horse was treated medically. Because signs of mild abdominal pain persisted and the heart rate had increased, an exploratory celiotomy was performed 30 hours after signs of colic were first noticed. At surgery, the ileum was found partially entrapped within the epiploic foramen, in a left-to-right direction, to form a parietal hernia. The entrapped intestin...
Fischer AT, Vachon AM.Laparoscopic intra-abdominal ligation and removal of cryptorchid testes in horses was evaluated retrospectively in 50 horses that underwent the procedure between 1991 and 1996. Sixty-one cryptorchid testes were removed by one of the following methods; the use of 1) an endoscoping stapling and transection device, 2) an endoscopic clipping device, 3) an endoscopic ligating loop. Monopolar electrosurgery was combined with these methods to facilitate coagulation and cutting of tissue. In 8 horses, 9 testes were retained between the internal and external inguinal rings. The inguinal testes were rem...
Bleyaert HF, Brown MP, Bonenclark G, Bailey JE.The purpose of this report was to describe the use of laparoscopy as a method of treatment for abdominal adhesions in the horse. Methods: Unilateral ovariectomy for removal of a granulosa cell tumor was performed through a diagonal paramedian approach in a 14-year-old Arabian mare. Progressive incisional swelling and hemorrhage culminated in acute incisional dehiscence with herniation of ileum on the sixth postoperative day. Septic peritonitis that responded to parenteral antibiotic therapy was identified 7 days after hernia repair. Seven days later, the mare had signs of abdominal pain, and a...
Santschi EM, Juzwiak JS, Moll HD, Slone DE.This clinical report describes surgical correction of diaphragmatic hernia in three young horses. Methods: Retrospective investigation of medical records and subsequent racing performance. Methods: Three young horses with diaphragmatic hernia. Results: Three young horses with signs of abdominal pain had diaphragmatic hernia causing small intestinal strangulation. The strangulated small intestine was resected and an end-to-end jejuno-jejunal (two horses) or a side-to-side jejuno-cecal anastomosis (one horse) was performed. Diaphragmatic hernias were closed with a continuous suture pattern. All ...
Ingle-Fehr JE, Baxter GM, Howard RD, Trotter GW, Stashak TS.The purpose of this study was to determine whether detection of bacterial contamination of ventral midline incisions was predictive of postoperative incisional complications in horses undergoing exploratory celiotomy for colic. Methods: Prospective study. Methods: Horses that had ventral median celiotomies for colic at Colorado State University between May 1, 1991 and April 30, 1993 were studied prospectively. Complete information was obtained on 66 horses. Methods: Bacterial cultures were obtained from ventral midline incisions at surgery. Information regarding the type of surgery performed (...
Honnas CM, Cohen ND.To determine the prevalence of wound infection following celiotomy in horses and to determine risk factors associated with the development of such infections. Methods: Prospective study. Methods: 210 horses that had 235 celiotomies. Methods: All horses that had celiotomies between March 1990 and March 1992 were considered for this study. Only horses that survived > or = 10 days after surgery were included in analysis of risk factors for postoperative wound infection. Results: Of the 210 horses, 161 (76.7%) were discharged; of the horses discharged, 147 horses had a single celiotomy and 14 had ...
Klohnen A, Wilson DG.Nonstrangulating indirect scrotal hernias were corrected in two 4-week-old Percheron foals by a laparoscopic technique. After laparoscopic reduction of herniated nonstrangulated small intestine each testes was retracted through the vaginal ring. The ligament of the tail of the epididymis was transected by electrocautery. The testicular vessels and nerves were isolated by cautery of the mesenteric portion of the mesorchium and then ligated. Staples were used to close the opening of the inguinal canal by apposing the peritoneal edges of the vaginal ring. Resection of umbilical stalk remnants via...
Riley CB, Cruz AM, Bailey JV, Barber SM, Fretz PB.Many uncomplicated umbilical hernias have been managed successfully in foals by the application of a hernia clamp. Isolated reports of complications following clamp application have led some authors to suggest that it is an unsuitable method of treatment. Little information has been published comparing the complication rates associated with the use of hernia clamps and herniorrhaphy in the treatment of umbilical hernias. The purpose of this retrospective study was to report the characteristics of clinical cases of umbilical hernia and to compare the complication rates following these 2 treatme...
Fischer AT, Vachon AM, Klein SR.Two mature stallions that were used for breeding purposes were admitted for evaluation of inguinal hernias. In 1 horse, the hernia was reduced per rectum by gentle traction applied to the intestine. In the other horse, the hernia was reduced by placing the horse in dorsal recumbency and applying external pressure over the scrotum. Both horses were observed for recurrence of the hernia. Seven days later, an elective laparoscopic technique for inguinal herniorrhaphy was performed on each horse, using polypropylene mesh. Complications did not develop, and both horses have successfully completed 2...
Wilson DA, Baker GJ, Boero MJ.Complications of celiotomy incisions were evaluated retrospectively in 274 horses that survived at least 1 month after surgery, or died or were euthanatized within 1 month of surgery, as a direct result of these complications. Horses were divided into four groups; group A, a ventral median celiotomy for intestinal disease; group B, ventral median celiotomy for nonintestinal disease; group C, repair of an umbilical hernia; and group D, celiotomy in a region other than the midline. Specific incisional complications were peri-incisional edema, drainage, incisional abscess, suture sinus, and dehis...
Perkins NR, Frazer GS.Topics addressed in this article include complications of castration, scrotal and inguinal hernias, torsion of the spermatic cord, traumatic injuries to the external genitalia, and posthumous collection of spermatozoa. A concise overview of the clinical management of emergency cases is provided.
van der Velden MA, Klein WR.During a 3-year period 21 horses were surgically treated because of large abdominal wall defects. In each case the defect was bridged with a polypropylene mesh, which was placed on the outside of the hernial ring. This was in contrast with the technique for mesh herniorrhaphy generally described in human and veterinary literature, in which the mesh is always implanted on the inside of the hernial ring. One horse was destroyed on the first postoperative day because of postanaesthetic myelomalacia. Surgical repair as described was successful in 18 patients. Recurrence of herniation occurred in t...
Foerner JJ, Ringle MJ, Junkins DS, Fischer AT, MacHarg MA, Phillips TN.A 7-year-old Thoroughbred mare underwent exploratory celiotomy for diagnosis and treatment of colic. An irreducible herniation of the large colon through the epiploic foramen was found. To reduce the hernia, the pelvic flexure was transected and the ends of the large colon were closed. The intercolonic mesentery was divided, and unaffected left ventral colon was moved into the epiploic foramen, providing sufficient space so that affected left dorsal colon could be reduced. The affected left ventral colon was then reduced and the diseased portion of both colons was resected. The colons were res...
Okamoto Y, Minami S, Matsuhashi A, Sashiwa H, Saimoto H, Shigemasa Y, Tanigawa T, Tanaka Y, Tokura S.The sponge-, cotton-, and flake-type remedies made of chitin (chitin-sponge, chitin-cotton, and chitin-flake, respectively), and non-woven fabric of polyester (NWF) composited with chitin (chitin-NWF) were applied to various types of trauma, abscess, surgical tissue defect and herniorrhaphy in 147 clinical cases including 72 dogs, 38 cows, 33 cats, 2 rabbits, one monkey and one horse. Chitin-sponge was applied in 30 cases as filling agent of surgical tissue defect, and in 25 cases of trauma, 31 cases of abscess as wound dressing or tissue defect filling agent. In 77 out of 86 cases (89.5%), go...
Everett KA, Chaffin MK, Brinsko SP.A diaphragmatic hernia in which 90% of the large colon had herniated through a 16-cm linear tear in the diaphragm was found in a 12-year-old Quarter Horse mare. Clinical signs included lethargy and exercise intolerance. Diagnosis of diaphragmatic hernia was made based on careful thoracic auscultation, combined with ultrasonographic and radiographic examination of the thorax.
Whitfield-Cargile CM, Rakestraw PC, Hardy J, Cohen ND, Davis BE.Repair of incisional hernias in horses has been described previously; however, this report describes the outcome of primary closure of incisional hernias in a large number of horses and compares these results with those of mesh implantation. Objective: To report the perioperative care, complications and long-term outcome of primary closure of incisional hernias in horses and to compare these results with a second population of horses in which prosthetic mesh was used. Methods: Medical records of horses undergoing an incisional herniorrhaphy between 1998 and 2009 were reviewed. Information obta...
van Loon JP, Meertens NM, van Oldruitenborgh-Oosterbaan MM, van Dijk R.A 3-year-old Friesian stallion was referred to the Department of Equine Sciences at Utrecht University with signs of colic. Laparotomy was performed and the stallion was castrated bilaterally because of an incarcerated inguinal hernia. Intestinal resection was not performed. Eight days postoperatively, the horse showed signs of severe colic and was admitted for re-laparotomy. After resection of 1.5 m of strangulated jejunum and severe intraoperative hypotension, bradycardia, and electrolyte disorders, the horse showed problems during recovery with signs of hindquarter paralysis. There was no p...
Tóth F, Schumacher J.Repair of hernias of the abdominal wall of horses is often augmented by inserting a prosthetic mesh. In this review, we describe the various characteristics of prosthetic meshes used for hernia repair and present 2 systems that are used by surgeons in the human medical field to classify techniques of prosthetic mesh herniorrhaphy. Both of these classification systems distinguish between onlay, inlay, sublay, and underlay placements of mesh, based on the location within the abdominal wall in which the prosthetic mesh is inserted. We separate the published techniques of prosthetic mesh herniorrh...
Scharner D, Winter K, Brehm W, Kämpfert M, Gittel C.Despite advances in surgical technique in abdominal surgery, incisional complications are frequently reported following ventral midline laparotomy in horses. The aim of this study was to determine the incidence of incisional complications at our clinic and to identify possible risk factors. Furthermore, we investigated whether suturing the peritoneum leads to a reduction of incisional complications. Methods: In this retrospective study, records of patients of the Large Animal Clinic for Surgery of the University of Leipzig from January 2010 to December 2015 were analysed. Horses with ventral m...
Freeman DE, Orsini JA, Harrison IW, Muller NS, Leitch M.Of 147 horses treated for umbilical hernias over a 13.5-year period, 13 horses (8.8%) developed complications in association with umbilical defects. Six horses had intestinal incarceration; the incarceration was reduced manually in 3 horses before admission, resolved without treatment in 2 others, and was surgically reduced in one. Herniorrhaphy was performed on 4 of the 5 horses in which the incarceration did not require surgical reduction, and the fifth was managed conservatively. A horse with a parietal hernia and a horse with intestinal stragulation were treated surgically; in the latter, ...
Vázquez FJ, Argüelles D, Muñoz JA, Genton M, Méndez Angulo JL, Climent F, Roquet I, Iglesias M, Velloso Álvarez A, Vitoria A, Bulnes F, Saitua A....Inguinal hernias (IHs) and ruptures are a relatively common condition in horses, occurring in foals (congenital) and adult (acquired) animals. A retrospective observational analysis was conducted on 40 cases that underwent laparoscopic surgery to close the VRs using barbed sutures alone or combined with other techniques. Signalment, clinical presentation, surgery, and follow-up data were obtained. In total, fifty-nine VRs were closed using barbed sutures (alone or in combination with other methods), with six cases performed prophylactically and forty-four due to acquired IH. Of the forty-four ...
Spurlock GH, Robertson JT.Five foals were admitted because of colic that developed within 24 hours after birth. Physical examination revealed swelling from the inguinal region to the cranial aspect of the prepuce. Through the skin overlying the swelling, distended loops of bowel could be palpated. The hernias could be reduced with the foals restrained in dorsal recumbency. Surgical exploration showed the swelling to be an inguinal hernia with small bowel herniation through a rent in the common vaginal tunic. Concurrent rupture of the vaginal tunic should be suspected when a congenital inguinal hernia is associated with...
Rutgers LJ, Kersjes AW.Complications following castration are increasingly often regarded as unacceptable by the owners of horses. A veterinary surgeon can only be held responsible for the consequences of his professional procedure when castration is not performed according to the rule (lege artis), i.e. if the surgeon failed to act in accordance with professional veterinary standards. So far, there is no consensus concerning the standard regarding the castration of stallions as various techniques are being used, and as some veterinary surgeons consider complications to be a normal risk in surgery. Visceral prolapse...
Gayle JM, Macharg MA, Smallwood JE.To report the clinical and surgical findings and outcome for horses with strangulating obstruction caused by herniation through the proximal aspect of the cecocolic fold. Methods: Retrospective study. Methods: Nine horses. Methods: Medical records were reviewed for clinical signs, surgical findings and technique, and outcome. Cadaver ponies and necropsy specimens were also used to study the regional anatomy of the cecocolic fold. Results: The ileum and distal jejunum were strangulated in 8 horses, whereas in 1 horse the small intestine and the left ascending colons were incarcerated in a rent ...
Markel MD, Pascoe JR, Sams AE.The medical records of 13 horses with strangulated umbilical hernias were reviewed. Typical history included increased swelling, warmth, and firmness of the hernial sac. Enterocutaneous fistulas had developed in 2 horses. Four horses had signs of abdominal pain. Surgery was performed on all horses, and the hernia was reduced by an open reduction technique. Incarcerated tissue included omentum (1 horse), jejunum (5), ileum (4), cecum (1), and ventral colon (2). All horses survived and were discharged from the hospital. Follow-up information on 9 horses (5 to 52 months after discharge) revealed ...
Caron JP.To report a technique for endoscopic component separation in horses and quantify the amount of body wall advancement obtained. Methods: Descriptive study. Methods: Fresh cadaveric horses (n = 14). Methods: After a preliminary anatomic study, 7 horses had unilateral endoscopic component separation involving transection of the external abdominal oblique fascia lateral to the rectus abdominis muscle. A laparoscope, placed using a balloon dissector, was used to create an intermuscular working space between the external abdominal oblique fascia and internal abdominal oblique muscle. A single instru...
Hanson RR, Todhunter RJ.Abdominal wall hernia was detected in 4 pregnant mares. Antemortem diagnosis of the specific abdominal wall lesion was difficult. Ventral deviation of the abdomen, associated abdominal wall edema, and pain indicated rupture of the prepubic tendon. Three mares examined at necropsy did not have a rupture of the prepubic tendon but did have herniation of the abdominal wall. Abdominal pain was severe and was compounded by incarceration or entrapment of viscus.
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...
Hill FW, Knottenbelt DC, van Laeren K.One month after falling heavily a four-year-old horse developed acute colic while being exercised. A tentative diagnosis of diaphragmatic hernia was reached on the basis of the clinical findings and confirmed at laparotomy. The defect was repaired and the horse made an uneventful recovery.
Caron JP, Mehler SJ.To report a technique for incisional hernioplasty in horses using laparoscopic placement of a prosthetic mesh. Methods: Case series. Methods: Horses (n=5) with ventral median abdominal incisional hernia. Methods: A telescope and 2 instrument portals were established bilaterally, lateral to and distant from the hernia margins. After exposure of the internal rectus sheath by removal of retroperitoneal fat with endoscopic scissors and monopolar cautery, a prosthetic mesh was introduced into the abdomen and secured intraperitoneally using transfascial sutures with or without supplemental endoscopi...
Gough R, McGovern K, Bladon B, De Oliveira F.This report describes two cases of spontaneous small intestinal evisceration via normally inserted umbilical stumps, without abdominal wall trauma. Both cases occurred immediately following uneventful parturition. The authors believe that these represent cases of umbilical cord herniation. This is a well-recognised condition in humans, but has not been previously described in equines. One foal died before veterinary intervention. The second foal underwent a jejunal resection with end-to-end anastomosis and survived to successfully race. This report describes a previously unrecognised condition...
Burns JJ, MacMillan K, Uehlinger FD, Riley CB.A stallion presenting for surgical correction of an acquired inguinal hernia was also diagnosed with a nephrosplenic entrapment (NSE) intraoperatively. Surgical intervention resulted in a successful outcome. To date, these conditions have not been reported to occur simultaneously. Un étalon présenté pour correction chirurgicale d’une hernie inguinale acquise a aussi été diagnostiqué avec une compression néphrosplénique pendant l’opération. L’intervention chirurgicale a été un succès. Jusqu’à maintenant, ces troubles n’avaient pas été signalés simultanément. (Traduit...

Wilson DG.A 3-year-old Standardbred gelding was referred for evaluation of a fluctuant swelling that developed over the dorsum of the carpus subsequent to arthroscopic surgery on that carpus. A synovial hernia was diagnosed and surgically repaired. Although complications secondary to arthroscopy are rare, synovial herniation can develop after arthroscopic surgery. The condition must be differentiated from the more common true bursitis or false bursitis that is commonly referred to as a hygroma.

Gracia-Calvo LA, Ezquerra LJ, Ortega-Ferrusola C, Martín-Cuervo M, Tapio H, Argüelles D, Durán ME.In order to know reproduction-related complications due to standing laparoscopic peritoneal flap hernioplasty, histological characteristics of the testicles from five stallions one year after surgery were compared with seven testicles from four healthy stallions. Moreover, the daily sperm output (DSO) was determined before (T0) and one year after surgery (T12). DSO did not show significant differences between T0 and T12. The diameter of the seminiferous tubules was significantly decreased in the samples from the hernioplasty group. The percentage of tubules with full spermatogenesis was smalle...
Kelmer G, Schumacher J.Abdominal incisional hernias in over 40 horses were repaired by exposing the hernial sac and ring and closing the ring with absorbable, interrupted, inverted, cruciate sutures after inverting the hernial sac into the peritoneal cavity. A mesh was sutured, under tension, over the closed ring. Placing the mesh subcutaneously, rather than in the retroperitoneal space, simplified the dissection and minimised the likelihood of penetrating the peritoneal cavity, a problem common to techniques of hernia repair in which the mesh is implanted into the retroperitoneal space. Implanting the mesh subcutan...
Belknap J, Arden W, Yamini B.A 2-month-old Standard-bred colt with signs of abdominal pain and large scrotum was found to have septic periorchitis involving the right testis. Surgical exploration of the abdomen and scrotum was performed; the colt was then castrated. Actinobacillus equuli was isolated from specimens obtained at surgery. The colt was treated with broad-spectrum antibiotics and flunixin meglumine after surgery, and fully recovered. The clinical signs of periorchitis in the colt were similar to an inguinal/scrotal hernia.
