Gastric retention associated with a pyloric mass in two horses.

This research article presents two cases of young female horses that experienced stomach retention due to partial obstruction in the pylorus, a part of the stomach. Abnormalities such as a large mass in the pyloric antrum were confirmed through medical imaging and surgical exploration. For the first horse, it was discovered post-mortem that chronic gastric ulceration was related to this issue. The second horse made a recovery after undergoing a surgical procedure called gastro-jejunostomy to bypass the affected areas.

Understanding the Condition

• The research discusses the medical condition of gastric retention, which is a disorder in horses marked by inhibited passage of food content from the stomach to the small intestine. The primary cause of this condition in the cases studied was the partial obstruction in the pylorus, a section of the stomach involved in the transition of food to the duodenum of the small intestine.

Case Presentation and Investigation

• In the course of diagnosing the condition, techniques such as contrast radiography – an imaging technique used to visualize the structures of the gastrointestinal tract – were deployed.
• The researchers also conducted what’s called an exploratory laparotomy, a surgical operation to inspect the abdominal organs, in which a large mass was found in the wall of the pyloric antrum in both horses.

Findings and Treatment Options

• In the first case, a post-mortem examination was carried out that established the association of the mass with chronic gastric ulcers, a type of lesion in the digestive system defined by the loss of tissues lining the stomach.
• While the researchers were unable to confirm gastric ulceration in the second horse, they were able to treat the animal effectively by performing gastro-jejunostomy surgery. This procedure creates a new connection between the stomach and jejunum, thus bypassing the pylorus and duodenum.

Implications and Insights

• This study provides useful insights into uncommon causes of gastric retention in horses, brings attention to the importance of accurate diagnosis through imaging and surgery, and proposes potential options for treatment.
• It also underlines the importance of post-mortem examinations in better understanding the health issues in animals, which in turn can inform and guide treatment for other cases.
