Summary: Background: Strangulating lesions of the small intestine involving the greater omentum (SSIGOs) have only rarely been reported. Furthermore, information pertaining to clinical descriptions, surgical findings and outcome is lacking. Objectives: The objective of this study was to describe the prevalence, clinical presentation, surgical findings, postoperative outcome and risk factors associated with SSIGOs. Study design: This is a retrospective case series of 32 horses with a diagnosis of SSIGOs. Methods: Data from hospital records of horses identified with SSIGOs between 2005 and 2020 including signalment, clinical findings at presentation, initial laboratory results, surgical findings, surgical procedures performed and postoperative survival were analysed. The prevalence of SSIGOs was determined. SSIGO was compared with small intestinal strangulating and nonstrangulating lesions and other types of colic to identify potential risk factors among signalment data and to determine outcome, using multiple logistic regression models. Results: SSIGOs were present in 2.3% (32/1413) of all horses undergoing exploratory laparotomy for colic, 4.7% of all horses with primary small intestinal lesions (32/683) and 5.6% of strangulating small intestinal lesions (32/570). Surgical findings included primary strangulation by the greater omentum with or without involvement of a lipoma‐like mass originating from the greater omentum (15/32 [47%]), adhesions involving the greater omentum leading to strangulation of the small intestine (14/32 [44%]) and small intestine incarceration through an omental rent (3/32 [9%]). The short‐term survival rate defined as survival until discharge was 53% (17/32) considering all SSIGO cases, and 85% (17/20) for SSIGO cases recovered from anaesthesia. Risk factors identified were increasing age and year of surgery. Main limitations: The limitations of this study are retrospective study design and the limited number of SSIGO cases reflecting the rarity of this condition. Conclusions: Numerous anatomical configurations of SSIGO exist, but clinical presentation is similar to other strangulating small intestinal lesions. Although uncommon, SSIGOs should be considered a potential cause of small intestine strangulation. [ABSTRACT FROM AUTHOR]

Summary: This case report describes the clinical presentation and management of a donkey admitted with acute signs of abdominal pain that was diagnosed with a bilateral Morgagni hernia, a rare type of congenital diaphragmatic hernia. For more than 8 months before presentation, the donkey had been showing signs of recurrent mild abdominal pain that responded favourably to medical treatment. On admission, the donkey had mild tachycardia and tachypnoea. Radiography and ultrasound of the thorax and abdomen showed thoracic herniation of the large colon. Exploratory laparotomy was performed, and the sternal and diaphragmatic flexures of the large colon, as well as the left hepatic lobe, were found incarcerated in a bilateral Morgagni hernia. Intestine and liver were removed from the hernia, and the large colon was exteriorised. The defect in the diaphragm was repaired by stapling a polyester mesh circumferentially around the hernia ring and covering the mesh with an excised section of the greater omentum. No further complications and no recurrence of colic were observed during an 8‐month follow‐up period. [ABSTRACT FROM AUTHOR]

Summary: Chronic orocutaneous, oronasal, or orosinus fistulae can be challenging to repair. This report describes placement of a dental bridge as a treatment for oral fistulae and outcome in two horses. A 12‐year‐old, Westphalian gelding was presented for nasal discharge because of an oromaxillary fistula after dental repulsion of the Triadan 209 4 years earlier. The second case, a 5‐year‐old Oldenburg mare was presented for an orocutaneous fistula 7 weeks after dental repulsion of the Triadan 208. Both were treated by placing an 8‐shaped cerclage wire, inserted through the rostral and caudal interdental spaces and crossing at the level of the missing tooth. Polymethylmethacrylate (PMMA) was then used to seal the fistula. No significant complications occurred during or after the surgery. In both cases clinical signs did not recur. In the first case the dental bridge is currently (5 years after the intervention) in place. In Case 2 the construction was removed after 1.5 years and the fistula had healed completely. This case report suggests that placing a dental bridge composed of cerclage wire and PMMA should be considered as an easy, noninvasive and efficient way to manage large oromaxillary or orocutaneous fistulae.

Background: Radial extracorporeal shockwave therapy (ESWT) is widely used in equine practice for the treatment of orthopedic problems. However, its original use as a lithotripsy device in human and canine urology led us to postulate that it could be used as an alternative to the surgical treatment of urethral calculi in horses. Hypothesis: Radial ESWT can easily and safely fragment calculi in the distal urethra of the horse. Animals: Two postmortem cases and 1 live case of obstructive urinary disease admitted at the Veterinary Teaching Hospital of Liege. Methods: A radial shockwave device was directly applied to the urethra in an attempt to fragment calculi. An ex vivo trial was performed on the same retrieved calculi to investigate pressure settings in order to obtain complete fragmentation of the calculus. Results: In all cases, radial ESWT was able to fragment the calculus partially, enabling retrieval of the remaining fragments via the urethra. Much higher pressure settings than those used for in vivo partial fragmentation were necessary to obtain complete destruction of the calculi ex vivo. Conclusions and Clinical Importance: This brief report suggests the use of radial ESWT as a safe and useful alternative to more invasive surgical management of urethral calculi in horses.
