Topic:Hernia
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.
Testicular perfusion after standing laparoscopic peritoneal flap hernioplasty in stallions. Acquired inguinal herniation is a very common condition in stallions, usually leading to unilateral or bilateral castration to prevent future recurrence. Recently, several surgical techniques such as the standing laparoscopic peritoneal flap hernioplasty (SLPFH) have been developed to avoid herniation recurrence and also preserve the breeding activity of high economic value stallions. However, studies on SLPFH lack more comprehensive and systematic data about reproductive-related adverse effects and outcomes. The aim of this study was to evaluate whether SLPFH of the internal inguinal rings pr...
Use of a novel silk mesh for ventral midline hernioplasty in a mare. Ventral midline hernia formation following abdominal surgery in horses is an uncommon complication; however, it can have serious consequences leading to increased morbidity and mortality. Currently, mesh hernioplasty is the treatment of choice for large ventral midline hernias in horses to allow potential return to normal function. Complications following mesh hernioplasty using polypropylene or polyester mesh in horses can be serious and similar to complications seen in human patients, including persistent incisional drainage, mesh infection, hernia recurrence, intra-abdominal adhesions, mesh...
Standing laparoscopic peritoneal flap hernioplasty of the vaginal rings does not modify the sperm production and motility characteristics in intact male horses. Laparoscopic hernioplasty techniques have been developed in the recent years to avoid the recurrence of inguinal hernias and to spare the testicles for breeding purposes in stallions. However, there have been no previous comprehensive and systematic studies of the reproductive outcomes and prognoses for stallions after inguinal hernioplasty. Therefore, the objective of this study was to assess the possible effects of one of these techniques (standing laparoscopic peritoneal flap hernioplasty) on the sperm production and motility characteristics of six healthy stallions that received this proce...

Diaphragmatic herniation in the horse: 31 cases from 2001-2006. Diaphragmatic rent and visceral herniation in the horse is seldom diagnosed, but historically carries a poor prognosis. The objective of this study was to document the presentation and surgical management of all diaphragmatic rents as presented to 2 referral institutions over a 5-year period. A review of 31 cases demonstrated that even with advances in surgical management of abdominal and thoracic conditions, little has been done to change the prognosis for this condition. Success rate was 23% for all horses presented for colic and were ultimately diagnosed with a diaphragmatic hernia, and 46%...
[The extent of temperature sense and pain appreciation recovery in the dermatomes of cauda equine roots after lumbar intervertebral dischernia elimination]. 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...
Post-anaesthetic myelopathy in a 3-year-old Friesian gelding. 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...
Inguinal herniation of the ascending colon in a 6-month-old Standardbred colt. To report inguinal herniation of the ascending colon in a Standardbred colt. Methods: Case report. Methods: A 6-month-old Standardbred colt. Methods: The colt underwent surgical exploration of the hernia with large colon resection and anastomosis.

Conclusions: Although uncommon, indirect inguinal herniation of the ascending colon can occur in young horses.
Abdominal wall reconstruction using biological tissue grafts. Synthetic mesh products have been used to repair abdominal wall defects (eg, hernias) for many years. Biological mesh products are now available as an option when synthetic mesh products are not appropriate. To correctly prepare biological tissue grafts for use in the OR, perioperative nurses must understand the types of grafts available. Biological tissue grafts may be harvested from human, porcine, bovine, or equine hosts and from skin, pericardium, or small intestine submucosa.

Update on recent advances in equine abdominal surgery. In recent years important advancements in colic surgery have led to improved prediction of survival rates, better survival rates, and decreased complication rates. This article describes several modalities to combat and prevent incisional hernia and intestinal adhesion formation in horses undergoing colic surgery. These modalities have had a positive impact on reducing complications in horses after surgery.
Laparoscopic mesh incisional hernioplasty in five horses. 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...
Repair of abdominal wall hernias in horses using primary closure and subcutaneous implantation of mesh. 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...
Retrospective analysis of exploratory laparotomies in 192 Andalusian horses and 276 horses of other breeds. The medical records of 468 horses that underwent 490 exploratory laparotomies for the correction of gastrointestinal diseases were reviewed to search for differences between Andalusian horses and other breeds. The seasonal distribution of surgical colics and their outcome and complications were also investigated. Bivariant analysis was used to compare the horses' age, gender and breed with the type of surgery, the bowel affected and the type of colic, and all these variables were compared in relation to euthanasia during surgery, complications, short-term survival and seasonal distribution. A ...
Evaluation of common vaginal tunic ligation during field castration in draught colts. The objective of this study was to determine if ligation of the common vaginal tunic could prevent or reduce the incidence of omental herniation and eventration in draught colts undergoing routine field castration. It was found that common vaginal tunic ligation, while not completely preventing omental herniation and evisceration, significantly reduced the incidence of these complications and should be considered in those males deemed at increased risk of significant post castration complications.
