Acute hemorrhagic enterocolitis

Last edited: 4/15/2026

Overview

Acute hemorrhagic enterocolitis (AHNE) is a severe, rapidly progressing inflammatory condition characterized by necrosis and hemorrhage in the gastrointestinal tract, often leading to significant morbidity and mortality. 1

Diagnosis

  • Clinical Presentation: Severe abdominal pain, toxic shock, altered mental status, fever, hypotension, abdominal tenderness, and rebound tenderness.
  • Imaging: Abdominal CT showing bowel wall thickening, colonic necrosis, and peritoneal effusion.
  • Laboratory Findings: Elevated inflammatory markers, leukocytosis.
  • Pathology: Necrosis and hemorrhage identified during surgical exploration or post-mortem examination. 1
  • Management

  • Fluid Resuscitation: Immediate fluid replacement to address hypovolemic shock.
  • Surgical Intervention: Exploratory laparotomy for definitive management, particularly in cases with significant necrosis or perforation.
  • Antibiotics: Broad-spectrum antibiotics initiated empirically, though efficacy may vary. 1
  • Supportive Care: Intensive care support for multi-organ dysfunction, including mechanical ventilation and renal replacement therapy if needed.
  • Special Populations

  • Elderly: Higher risk of severe complications and mortality, as evidenced by the reported case of a 70-year-old patient. 1
  • Key Recommendations

  • Prompt Surgical Evaluation: Immediate surgical consultation and exploration for patients with suspected AHNE, especially with signs of necrosis or shock. (Evidence: Weak 1)
  • Aggressive Fluid Resuscitation: Initiate aggressive fluid resuscitation to manage hypovolemic shock promptly. (Evidence: Weak 1)
  • Empirical Antibiotic Therapy: Start broad-spectrum antibiotics early in the management course, though efficacy should be monitored closely. (Evidence: Weak 1)
