Visceral prolapse after castration in the horse: a review of 18 cases.

The research investigates an issue of visceral prolapse occurring after castration in horses over a 10-year period. The study recommends the use of half-closed castration and prompt treatment as means to minimize risks and favorably address cases of visceral prolapse.

Research Background and Findings

• The study was conducted over a decade-long period during which 18 horses that had undergone castration developed a condition known as “visceral prolapse”.
• Visceral prolapse is a serious surgical complication in horses, where the internal organs (such as intestines and omentum) herniate or “prolapse” through the castration site.
• Surgical interventions were performed to treat these horses. The outcomes varied depending on the type of prolapse, with a success rate of 100% (6 out of 6) in cases of omental prolapse and 66% (8 out of 12) in cases of intestinal prolapse. Omental prolapse refers to the herniation of the fatty lining (omentum) around the abdominal organs, while intestinal prolapse entails the herniation of a part of the intestine.

Preferred Surgical Method and Prognosis

• After reviewing these cases, the researchers suggest the preference for a half-closed castration technique over an open castration technique. In a half-closed castration, part of the outer covering of the testicle (parietal vaginal tunic) is left intact and ligated, which may help in minimizing the risk of visceral prolapse.
• The study emphasizes the importance of prompt and adequate treatment in managing cases of post-castration visceral prolapse in horses. According to the authors, when immediate treatment measures are employed, the prognosis for horses experiencing this complication appears to be favorable. This implies that horses can recover successfully if the condition is diagnosed and treated quickly and appropriately.
