Ischemic gastroenteritis

Last edited: 4/16/2026

Overview

Ischemic gastroenteritis results from inadequate blood supply to the gastrointestinal tract, leading to ischemia and potential necrosis, often seen in specific populations rather than general clinical practice 1.

Diagnosis

  • Clinical presentation includes severe abdominal pain, nausea, vomiting, and bloody stools 1.
  • Imaging studies (e.g., CT angiography) can identify vascular occlusions or compromised blood flow 1.
  • Endoscopy may reveal ischemic changes but is contraindicated if perforation is suspected 1.
  • Laboratory tests often show elevated inflammatory markers and electrolyte imbalances 1.

    • Management

  • Immediate resuscitation with fluid and electrolyte replacement is critical 1.
  • Early surgical intervention may be necessary for suspected bowel necrosis or perforation 1.
  • Pharmacological management includes antiplatelet agents (e.g., aspirin) and anticoagulants if underlying thrombosis is identified 1.
  • In cases of severe ischemia, bowel resection might be required 1.

    • Special Populations

  • No specific guidelines provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.

    • Key Recommendations

  • Initiate urgent fluid resuscitation and monitor electrolytes closely (Evidence: Strong 1).
  • Consider CT angiography for diagnosis and to assess vascular involvement (Evidence: Moderate 1).
  • Prompt surgical evaluation is advised if clinical suspicion of bowel necrosis or perforation exists (Evidence: Expert opinion 1).
