Duodenitis-Proximal Jejunitis (DPJ)
GastrointestinalEquineNew
Key Points
  • Duodenitis-proximal jejunitis (DPJ) is an acute inflammatory condition of horses, characterised by functional ileus in the proximal small intestines, fluid accumulation and distension
  • The exact cause is unknown but Clostridial bacteria are commonly implicated
  • The hallmark features are acute abdominal pain and copious nasogastric reflux
  • Ongoing fluid sequestration in the intestines leads to dehydration, electrolyte imbalances and hypovolaemia
    • Endotoxaemia is also common due to bacterial translocation or endotoxins moving across the compromised intestinal mucosa
  • Diagnosis is based on clinical presentation and exclusion of differentials
  • DPJ is managed medically with gastric decompression and aggressive supportive care
Differential Diagnoses
  1. Gastrointestinal obstruction
  2. Small intestinal strangulation
  3. Ileal impaction
