[Occurrence of so-called spontaneous ruptures in the rectum of horses. 1. Pathologicoanatomic and experimental studies].

The research article investigates the causes of spontaneous ruptures in the rectum of horses. The findings suggest that ruptures often occur in areas of the horse rectum with weaker muscular development, and that these ruptures are more likely to happen during rectal examination due to the lower resistance in these areas.

Rectum Structure in Horses

• The study starts by examining the structure of the rectum in horses, highlighting that the muscular coat is not uniformly developed across the organ. In particular, a region called the “ampulla roof”, characterized by a wave-like structure, is identified as having a particularly weak muscular development.
• Due to the weaker muscular coat, this area is considered as a place of minor resistance, making it more susceptible to damages.

Causes of Rectal Ruptures

• The research points out that ruptures in the intestinal wall frequently occur in these areas of minor resistance.
• Ruptures are not only common but are also able to be reproduced in controlled experimental conditions. Therefore, the evidence supports the hypothesis that weaker muscles in certain areas of the horse’s rectum, like the ampulla roof, increase the likelihood of ruptures.

Risks During Rectal Examination

• Based on the findings, the authors warn about the potential risks of rectal examination in horses. A comprehensive understanding of the structure of the rectum and the application of appropriate examination techniques are essential to minimize the risk of causing any harm.
• A lack of caution during the examination could result in damage to the rectum, leading to severe health consequences for the horse.

Legal Implications of Rectal Ruptures

• Moreover, the study discusses the legal implications of rectal ruptures. For instance, the responsibility of any veterinary professionals involved in the examination is brought into question when rupture incidents occur.
• The authors express that if ruptures happen despite following all veterinary procedures and precautions, proving the investigator’s blamelessness can be very challenging. This further stresses the urgency for proper knowledge and careful execution of rectal examinations in horses.
