Diagnosing obscure gastrointestinal bleeding, often from small bowel arteriovenous malformations (AVMs), remains challenging. Intraoperative endoscopy offers a definitive solution for identifying and treating these elusive bleeding sources.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Diagnostic Imaging

Background:

  • Occult gastrointestinal bleeding between the ligament of Treitz and ileocecal valve presents diagnostic challenges.
  • Existing diagnostic modalities like endoscopy, nuclear scans, and angiography have limitations.

Observation:

  • An 18-year-old male presented with obscure gastrointestinal bleeding.
  • A comprehensive diagnostic workup included multiple endoscopic procedures, nuclear scans, video capsule endoscopy, and angiography.
  • Conventional methods failed to pinpoint the bleeding source.

Findings:

  • Arteriovenous malformations (AVMs) in the small bowel were identified as the source of bleeding.
  • Intraoperative endoscopy, performed via a small bowel enterotomy, successfully located the AVMs.

  • Resection of the identified AVMs resolved the gastrointestinal bleeding.

    • Implications:

    • Intraoperative endoscopy is a valuable technique for diagnosing and treating obscure gastrointestinal bleeding.
    • This approach can overcome the limitations of standard diagnostic tools for small bowel pathology.
    • Effective management of AVMs can significantly improve patient outcomes in cases of obscure GI bleeding.
