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.
Bauck AG, Nelson E, McLain A, Cock G, Sanchez LC, Freeman DE.To describe a modified celiotomy to improve access to cranial abdominal structures in horses. Methods: Four horses. Methods: Short case series. Methods: Three horses with gastric impactions were treated with gastrotomies. One horse was treated for a diaphragmatic hernia with herniorrhaphy and mesh augmentation. In all horses, the ventral midline celiotomy was modified cranially with a J-incision through the body wall, along the paracostal arch. Results: The only surgical complications were midline incisional infections in all horses. Three of the four horses had good long-term outcomes; the re...
Terschuur JA, Coomer RPC, Handel I, Pressanto MC, McKane SA.Skin closure of laparotomy incisions using topical 2-octyl cyanoacrylate (2-OCA) mesh provides a secure bactericidal barrier in humans, which may reduce the risk of postoperative incisional complications. However, the benefits of using this mesh have not been objectively assessed in horses. Methods: From 2009 to 2020, three methods of skin closure were used following laparotomy for acute colic, including metallic staples (MS), suture (ST) and cyanoacrylate mesh (DP). The closure method was not randomised. Owners were contacted 3 months or more after the surgery to record any postop...
Avison A.Umbilical hernias are among the most common congenital defects in horses. Complications of umbilical hernias are uncommon, and Richter's hernias are rare. This report describes a case of Richter's hernia in a 3-month-old colt that was presented with signs of acute colic. The foal underwent a herniorrhaphy with intestinal resection and anastomosis. Hernie de Richter chez un poulain âgé de 3 mois — une rare manifestation. Les hernies ombilicales figurent parmi les défauts congénitaux les plus communs chez les chevaux. Les complications des hernies ombilicales sont peu fréquentes et les he...
Abu-Seida A.Diaphragmatic hernia (DH) represents an acute abdominal crisis, but respiratory symptoms may be occurring. Different types of diaphragmatic hernias (DHs) like typical DH, Morgagni hernia, hiatal hernia and diaphragmatic diverticulum have been recorded in equids. These DHs have various clinical presentations and prognoses. Early diagnosis and prompt surgical repair are highly recommended in order to diminish the ischemic changes to thoracic and abdominal viscera, thus improving the overall prognosis of equids with DH. Over last decade, the prognosis of DH in equids was better than previously be...
Williams TL, Mochal-King C, Rude BJ, Weed BC, Nicodemus MC.Cecal and ileal cannulations have previously been used to determine equine digestibility and define gastrointestinal physiology. However, research has been limited to specific portions of the equine digestive tract lacking utilization of dual cannulations. The purpose of this study was to develop and implement surgical and preoperative and postoperative procedures for cannulation of dual sections, ileum and cecum, of the equine digestive tract including development of recommendations for addressing postsurgery complications. A total of 8 ponies went through surgical procedures for the placemen...
Lambertini C, Bombardi C, Zannoni A, Bernardini C, Dondi F, Morini M, Rinnovati R, Spadari A, Romagnoli N.Proteinase activated receptor 4 (PAR) in the gastrointestinal tract is involved in the regulation of inflammation and pain pathways. The aim of the present study was to evaluate the distribution and expression of PAR in the jejunum of healthy horses and in the pathologic tracts from horses undergoing surgery for herniation of the small intestine through the epiploic foramen. Eight healthy horses (Group H) and eight horses with epiploic hernia (Group EH) were included; the jejunum samples were collected at the slaughter or intraoperatively after enterectomy, respectively. To evaluate PAR expres...
Crosa AT, Katzman SA, Kelleher ME, Nieto JE, Kilcoyne I, Dechant JE.This study reports the prevalence of and risk factors for incisional complications in equids after ventral midline celiotomy for enterolithiasis. This study covered the years 2008 to 2015 and included 72 equids. Enteroliths were removed from the ascending or descending colon through 1 or more enterotomies. Complications were defined as surgical site infection and/or incisional hernia formation. Follow-up by telephone questionnaire or medical records determined that 10/72 (13.9%) equids experienced complications, with 6/72 (8.3%) developing a surgical site infection and 5/72 (6.9%) a hernia. Se...
Shchurova EN, Khudiaev AT.Temperature sense and pain appreciation has been studied in the dermatomes of cauda equine roots in patients with lumbar intervertebral disc hernia before treatment, in the immediate and long-term periods of observation after disc hernia elimination. Temperature sense and pain appreciation has been determined to be disordered not only in the dermatome of compressed root, but in the dermatomes located proximally and distally as well. The manifestation of negative changes was observed to a greater extent during temperature sense examination. After disc hernia elimination the recovery of temperat...
Moustafa A, Elmetwally M, El-Khodery S, Hamed M, Gomaa N, Rizk MA.There is a paucity of information regarding the frequency and risk factors associated with the occurrence of an abdominal hernia in different equine species especially donkeys, and mules. In addition, the effectiveness of using polypropylene mesh for the surgical management of abdominal hernia in donkeys and mules is still unknown. The purpose of the present study was to evaluate the efficacy of using polypropylene mesh for the surgical treatment of abdominal hernia in horses, donkeys, and mules and to address the occurrence and risk factors associated with an abdominal hernia in the selected ...
Wheat JD.The migration of strongyle larvae is the most common or basic underlying cause of colic in the horse. Disease conditions producing symptoms of colic occur in all sections of the intestinal tract and consist of impactions, torsions, herniations and foreign bodies. Colic also occurs as a result of pre- and post-partum diseases such as torsion of the uterus, haemorrhage, rupture and inversion of the uterus. In general, lesions resulting in circulatory obstruction are the types requiring surgical intervention. There are six general types of small intestine obstruction that lend themselves to surgi...
Bertone AL, Stashak TS, Sullins KE, Ralston SL.Ten normal horses had approximately 95% of the length of the large colon resected with a side-to-side anastomosis between right ventral and right dorsal colon performed with surgical stapling equipment. Four horses died shortly after surgery of colitis (1 horse) or failure of the TA 90 transection staple line (3 horses). Another horse died 4 months after surgery from disseminated streptococcal infection but had recovered well from the colon resection. Five horses survived long term (18 months) with no clinical evidence of adverse effects of the resection. Surviving horses had weight loss and s...
Vitoria A, Barrachina L, Romero A, Fuente S, de Blas I, Gil L, Vázquez FJ.A new surgical technique using a polyether ether ketone (PEEK) anchoring device for testicle-sparing laparoscopic inguinal hernioplasty in stallions was described in 2023 and is known as the PEEK harpoon technique (PHT). In breeding stallions, it is essential that the surgery is effective in preventing inguinal hernia but also that it does not impair the testicular function. This study aims to evaluate whether the PHT may affect testicular function. To achieve that, changes in the testicular blood flow, sperm production and motility characteristics were assessed 28 days after use of the PHT. S...
