Acute small intestinal injury associated with hematomas in the mesentery of four horses.

This study examines four cases of acute small intestinal injury in horses linked to hematomas in the mesentery. It offers insights on these injuries, their management, and how they should be considered in differential diagnoses for horses showing symptoms of depression, anorexia, and progressive signs of colic.

Introduction to Study and Cases

• The paper discusses the examination of four horses showing signs related to small intestinal disease.
• Different issues were discovered in each horse, with two having primary hematomas in the mesentery. In contrast, the other two developed hematomas because of a mesenteric rent and strangulation of the bowel by a mesenteric lipoma, respectively.

Procedures and Outcomes

• The horses were taken through exploratory surgery to identify the causes of their conditions.
• For two of the horses, the hematomas were so extensive that they couldn’t be ligated, leading to their euthanization due to a high risk of continued postoperative bleeding.
• The other two horses underwent surgery successfully but developed complications afterward. One developed functional ileus requiring another surgery to decompress the bowel. The other had to be euthanized due to severe, repeat signs of colic.

Key Findings and Recommendations

• This investigation presents, as per the authors, the first documented cases of small intestinal infarctions secondary to hematomas in the mesentery.
• The authors recommend inclusion of primary mesenteric hematomas in the differential diagnoses for horses showing signs of depression, anorexia, and progressive signs of colic.
• They also review clinical signs and management strategies for a range of other small intestinal issues in horses, including volvulus, epiploic entrapment, intramural hematoma, mesenteric rent, and intussusception.

Implications of the Study

• This research intends to improve understanding and diagnosis of small intestinal diseases in horses, particularly those tied to hematomas in the mesentery.
• It also highlights the need for careful postoperative care to monitor and manage complications that might arise, ensuring more successful outcomes.
