Early herniorrhaphy of large traumatic abdominal wounds in horses and mules.

This research investigated the effectiveness of performing herniorrhaphy (without mesh) within 21 days of initial injury for the repair of external traumatic lateral abdominal hernias in horses and mules. The findings drew upon a case series of 22 subjects and revealed that such early surgical intervention could lead to successful recovery and prevention of hernia recurrence.

Research Methodology

• The study employed a descriptive case series approach, focusing on 22 cases of horses and mules with traumatic abdominal hernias.
• The subjects underwent surgical treatment involving exposure of the hernia sac, followed by closure of the abdominal wall defect through interrupted Mayo mattress or cruciate sutures after reducing the herniated organ back into the peritoneal cavity.
• Data was collected on various aspects such as the cause and location of the hernia, surgical findings, immediate and long-term complications after surgery, return to functionality, convalescence period and recurrence of hernia.

Research Findings

• The most common cause of hernia, in both horses and mules, was found to be falls, particularly while traversing impassable pathways.
• Adhesion to the underlying viscera was discovered in two of the cases during surgery.
• All animals, bar a few exceptions (3 with suture abscesses and one with a subcutaneous seroma), experienced uncomplicated healing.
• Follow-up conducted 6-24 months post-surgery indicated complete recovery without recurrence of the hernia and a successful return to previous work for the animals.

Conclusions

• The findings suggest that early herniorrhaphy within 21 days, using interrupted Mayo mattress or cruciate pattern sutures, can be an effective treatment option for external traumatic abdominal hernias in horses and mules.
• This approach might circumvent the traditionally preferred delay of 2-3 months for such surgical treatment, aiding quicker recovery and prevention of hernia recurrence.
