Equine Duodenitis-Proximal Jejunitis Study Guide
Overview and Clinical Importance
Duodenitis-proximal jejunitis (DPJ), also known as anterior enteritis or proximal enteritis, is an acute inflammatory condition of the proximal small intestine (duodenum and proximal jejunum) characterized by ileus, massive nasogastric reflux, and systemic signs of toxemia. This condition is frequently tested on the NAVLE due to its clinical importance, diagnostic challenges, and potential for life-threatening complications.

Understanding the pathophysiology, clinical presentation, and appropriate management is essential for equine practitioners and critical for board examination success.
