Diagnostic and Treatment Challenges for Diaphragmatic Hernia in Equids: A Concise Review of Literature.

This research article reviews the challenges associated with diagnosing and treating diaphragmatic hernia (DH), a severe abdominal condition, in equids like horses and donkeys. It details various types of DHs, their symptoms, impacts, and discusses the improved prognosis due to advances in medical technologies. Despite these advancements, it acknowledges ongoing struggles in diagnosis and treatment and offers recommendations for overcoming these hurdles.

Types of Diaphragmatic Hernias in Equids

• The authors detail four major types of diaphragmatic hernias in equids: typical DH, Morgagni hernia, hiatal hernia, and diaphragmatic diverticulum.
• Each hernia type varies in their clinical presentations and prognoses, impacting the respiratory and digestive system of the animal.

Improvements in the Prognosis of DH

• The prognosis for DH in equids has improved over the last decade due to advancements in medical technologies and surgical practices.
• Improvements include refined diagnostic tools, enhancements in general anesthesia methods, particularly for those with systemic compromise, advances in gastrointestinal surgery procedures, development of thoracoscopic techniques, and use of staples for surgical repair.

Challenges in Diagnosis and Treatment

• The authors point to several continuing challenges in the diagnosis and treatment of DH in equids. These include inconsistent clinical signs, the acute nature of the associated colic or stomach pain, and the absence of advanced diagnostic tools.
• Treatment challenges include risks associated with anesthesia, the difficulty in reducing large herniated organs, and the herniorrhaphy procedure itself, which is used to repair hernias.
• To overcome these challenges, the authors recommend increased awareness, careful clinical observation, using the best available diagnostic tools, careful preoperative stabilization and monitoring, choosing the most suitable surgical approach, and providing substantial intraoperative and postoperative support.

Conclusions and Future Directions

• Surgical repair, particularly prosthetic herniorrhaphy, is effective in closing the diaphragmatic defect and preventing recurrences.
• This review describes the different types of DHs in equids, their associated diagnostic and treatment challenges, and gives recommendations on how to overcome these hurdles to enhance the overall prognosis for animals suffering from DH.
