Angiodysplasia of stomach

Last edited: 4/23/2026

Overview

Angiodysplasia of the stomach refers to abnormal blood vessel formations that can lead to chronic bleeding, often resulting in iron deficiency anemia requiring frequent transfusions despite endoscopic interventions 1.

Diagnosis

  • Endoscopic identification of characteristic vascular malformations 1.
  • Imaging studies (e.g., angiography) may be used to confirm diagnosis and assess extent 1.
  • Laboratory findings typically include iron deficiency anemia and sometimes iron deficiency without overt bleeding 1.
  • Management

  • First-line: Endoscopic therapy (e.g., thermal coagulation, sclerotherapy) 1.
  • Adjunctive:
  • - Octreotide long-acting release (40 mg intramuscular every 28 days) may reduce transfusion requirements 1. - Standard care includes continued endoscopic management and supportive treatments like iron supplementation 1.

    Special Populations

  • Elderly: Management principles similar to general population, with emphasis on minimizing procedural risks 1.
  • Comorbidities: No specific recommendations provided; focus on managing underlying conditions and bleeding control 1.
  • Key Recommendations

  • For patients with angiodysplasia-related anemia requiring frequent transfusions, consider octreotide long-acting release (40 mg every 28 days) to potentially reduce transfusion needs (Evidence: Moderate) 1.
  • Primary management should include endoscopic interventions aimed at controlling bleeding sources (Evidence: Strong) 1.
  • Regular monitoring and supportive care, including iron supplementation, are essential adjuncts to bleeding control strategies (Evidence: Expert opinion) 1.
