Abdominal Hernia in Equine: Animal Level Risk Factors and Repair Using Polypropylene Mesh

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 animal species. Based on clinical and ultrasound proof of abdominal hernia, 48 animals were included in the current study. A questionnaire was created to imply the assumed risk factors associated with occurence and clinical findings of abdominal hernia. Hernioplasty using polypropylene mesh was used for the surgical treatment. The abdominal hernia was prevalent (P < .05) in foals followed by adult horses, donkeys, and mules (25, 15, 6, and 2), respectively. Ages from 3 to 5 years exhibited more abdominal hernias in donkeys, mules, and horses (12.5%, 4.2%, and 31.3%, P < .05), respectively. In all studied animals, females were more prevalent than males (70.8%, n = 34 vs. 29.2%, n = 14) respectively. The complication of abdominal wall hernia was positively affected by the time to repair admitted cases (P = .000). The majority of the animals (36 cases) recovered without complications, however, 10 cases had mild difficulties such as suture abscess, wound infection, serous fluid accumulation, and hematoma postsurgery. In addition, two cases of postoperative recurrence were documented. The results herein indicated that polypropylene mesh hernioplasty may be an alternative to the treatment of equine abdominal hernia. Recognizing the potential risk factors associated with an abdominal hernia in different equine species may be helpful to construct the best preventive measures.
