An atypical presentation of a mesenteric Meckel’s diverticulum in a 7-year-old warmblood mare: case report.

Abstract: Meckel's diverticula are a rare cause of small intestinal strangulation, diagnosed at laparotomy or necropsy. This congenital anomaly of the gastrointestinal tract originates from a remnant of the vitelline duct. In reported equine cases, they present as a full-thickness diverticulum on the antimesenteric border of the distal jejunum or proximal ileum. Methods: On laparotomy a Meckel's diverticulum positioned at the mesenteric side was found to be the cause of small intestinal strangulation. This position is very uncommon and to the best knowledge of the authors there is no unambiguous description of another case. Conclusions: Meckel's diverticula should be on the list of differential diagnoses in cases of small intestinal strangulation. As in humans, equine Meckel's diverticula can have the standard antimesenteric as well as a more exceptional mesenteric location. This case adds to the series of anecdotal reports of anomalies with regard to Meckel's diverticula in the horse.

This research article presents a rare case of small intestinal strangulation in a 7-year-old warmblood mare caused by Meckel’s diverticulum, a congenital anomaly in the gastrointestinal tract. The authors suggest that Meckel’s diverticula should be considered as a potential cause of such issues, even though its presence in the mesenteric side, the case in this study, is very uncommon.

Overview of the Study

  • The study focuses on the presentation of Meckel’s diverticulum, a congenital anomaly of the gastrointestinal tract, in a 7-year-old warmblood mare. This unusual defect is renowned as a rare cause of small intestinal strangulation in equines.
  • The authors describe the studied horse’s diverticulum as full-thickness and positioned on the mesenteric side, causing strangulation of the small intestine. This placement is notably uncommon in reported equine cases, which generally find the diverticulum on the antimesenteric border of the distal jejunum or proximal ileum.

Methodology

  • The researchers performed a laparotomy—a surgical procedure involving a large incision through the abdominal wall—to diagnose and treat the small intestinal strangulation. During this procedure, they located the Meckel’s diverticulum at the mesenteric side, a position rarely observed in equines.

Conclusions and Recommendations

  • Following the case study, the authors concluded that veterinary professionals should consider Meckel’s diverticula in differential diagnoses when dealing with equine cases of small intestinal strangulation.
  • The authors also highlighted that, similar to human instances, equine Meckel’s diverticula could also be located not only at the standard antimesenteric side but also at the more unusual mesenteric side. This finding further increases the need for increased awareness about the potential anomalies regarding Meckel’s diverticula in horses.

Significance of the Study

  • The research adds valuable insight to the minimal literature about mesenteric Meckel’s diverticulum in horses. By sharing their unusual findings, the authors encourage others to keep a broader perspective when diagnosing and treating cases of small intestinal strangulation in equines.
  • This study additionally serves as an alert to veterinary practitioners to remain mindful of typically rare anomalies in horses, thereby improving intervention strategies, enhancing diagnostic accuracy, and potentially increasing survival rates in such cases.
