Chronic ileocecal intussusception in horses.

The research paper describes a study conducted on ten young horses that were experiencing symptoms of partial obstruction in their small intestines. The study discovered that these symptoms were caused by chronic intussusception of the distal ileum into the cecum, and that surgical correction led to recovery in most cases.

Introduction

This research centred around ten young horses experiencing symptoms of simple partial obstruction in the small intestines. These symptoms included a general lack of physical well-being, variable levels of abdominal pain, depression and poor appetite. Initial diagnostic methods such as laboratory tests proved unhelpful in diagnosing the issue.

Diagnostic Findings

• Upon surgical exploration, the horses were found to have chronic intussusception of the distal ileum into the cecum, a condition where one segment of the intestine ‘telescopes’ into another, causing intestinal obstruction.
• Rectal examination in eight of the horses suggested a partial or intermittent obstruction of the small intestine.
• Aside from the symptomatology, significant dilation and hypertrophy were discovered in the distal sections of the small intestine, particularly the jejunum and ileum. These findings indicated a chronic progression of the intussusception.

Surgical Intervention and Outcome

• The recommended treatment involved a surgical correction through an end-to-side or side-to-side anastomosis, a procedure that connects healthy sections of the small intestine directly to the cecum.
• This surgical intervention led to recovery in seven out of the eight horses that were followed up long-term post-surgery.
• Interestingly, the study found that a failure to resect, or remove, the abnormal segment of the small intestine during the surgery did not affect the overall prognosis or recovery rate.

Conclusion

Overall, this research highlights chronic ileocecal intussusception as a potential cause of simple partial small intestine obstruction in young horses. Despite initial lab tests not providing significant insight, surgical intervention proved to be an effective treatment and resulted in a high recovery rate irrespective of resection of the abnormal intestinal segment.
