Dorsal displacement of the left ventral and dorsal colon in two horses.

This research describes the symptoms and surgical treatments of two cases of dorsal displacement in horses, where the colon moves into an unusual position, causing pain. The study further reports the full recovery of the animals post-surgery, though one required an additional operation due to a relapse.

Understanding the Research

• The paper focuses on a specific veterinary condition called dorsal displacement in the left ventral and dorsal colon, which had been observed in two horses. Dorsal displacement refers to the colon moving into an unusual position, specifically into a space surrounded by the base of the spleen, the top of the suspensory ligament of the spleen (also known as the phrenicosplenic ligament), the left kidney, and the adjacent body wall.
• Characteristics of this displacement include moderate to severe pain in the horse, minimal indications of shock, no positive response to medical therapies, and a tendency for a ventral midline abdominal paracentesis to enter the spleen. A ventral midline paracentesis refers to a procedure where a puncture is made in abdomen’s midline to collect fluid or to relieve pressure.

Surgical Intervention and Outcome

• This displacement condition is treated surgically, which aims to restore the colon to its regular place. The study highlights that simply relying on medical therapy is not suitable for treating this condition, indicating the level of severity and complexity associated with it.
• Post-surgery, both horses recovered successfully; however, in one of the cases, recurrence of the problem was observed, which necessitated another laparotomy. A laparotomy is a surgical procedure involving a large incision through the abdominal wall to gain access into the abdominal cavity. Recovery from this additional laparotomy was good, and the horse was back to health.

Implications and Significance of the Research

• This paper offers valuable insights for the veterinary field, especially for those dealing with horse health. It provides an understanding of the symptoms, diagnosis, and surgical treatment of the dorsal displacement of the colon, thus helping in effectively managing such conditions and improving the horse’s overall welfare.
• The evidence of successful recovery post-surgery, even in the case with a recurring problem, indicates the efficacy of the surgical protocol used which can be adopted by other vets encountering similar cases.
• In addition, the paper also suggests that more research may be needed to explore why this displacement occurs in the first place and to investigate whether there are preventive measures that could be taken to avoid such displacements. This could potentially minimize the need for invasive surgeries in the horses and enhance their health and endurance.
