BACKGROUND: Gastroenteric angiodysplasia (AD) is a vascular lesion characterized by vascular ectasias to the submucous sheath of the gastrointestinal tract. Lesions can be flat or raised, isolated or grouped and can break or ulcerate causing acute hemorrhage or, more commonly, chronic bleeding. CASE-REPORT: We describe a 65-year-old patient with a 3-yr history of chronic renal failure (CRF), who gradually developed anemia (hemoglobin (Hb) 10 g/dl) without any episodes of clinically relevant bleeding or any exposure to bleeding risk factors. Blood pressure (BP) was normal and renal function was stable (serum creatinine (Cr) 1.9 mg/dl). Routine laboratory tests showed a slight reduction in serum iron and transferrin saturation and a slightly elevated absolute reticulocyte count. These findings were associated with a positive occult gastrointestinal blood test and raised the clinical suspicion of chronic gastrointestinal blood loss. Oesophagogastro-duodenoscopy and colonoscopy demonstrated an absence of significant lesions, suggesting the need to investigate for a lesion localized in the small intestine. Capsular endoscopy, a recently developed endoscopic technique, particularly suited for small bowel pathology, was performed, and demonstrated the presence of an angiodysplasic lesion, located in the jejunum.

Abstract

BACKGROUND: Gastroenteric angiodysplasia (AD) is a vascular lesion characterized by vascular ectasias to the submucous sheath of the gastrointestinal tract. Lesions can be flat or raised, isolated or grouped and can break or ulcerate causing acute hemorrhage or, more commonly, chronic bleeding. CASE-REPORT: We describe a 65-year-old patient with a 3-yr history of chronic renal failure (CRF), who gradually developed anemia (hemoglobin (Hb) 10 g/dl) without any episodes of clinically relevant bleeding or any exposure to bleeding risk factors. Blood pressure (BP) was normal and renal function was stable (serum creatinine (Cr) 1.9 mg/dl). Routine laboratory tests showed a slight reduction in serum iron and transferrin saturation and a slightly elevated absolute reticulocyte count. These findings were associated with a positive occult gastrointestinal blood test and raised the clinical suspicion of chronic gastrointestinal blood loss. Oesophagogastro-duodenoscopy and colonoscopy demonstrated an absence of significant lesions, suggesting the need to investigate for a lesion localized in the small intestine. Capsular endoscopy, a recently developed endoscopic technique, particularly suited for small bowel pathology, was performed, and demonstrated the presence of an angiodysplasic lesion, located in the jejunum.
