Massive GI bleeding in a patient with 2 small AVMs in the small intestine: a case report
نویسندگان
چکیده
A 53 year-old Caucasian man with no previous history of gastrointestinal bleeding presented with sudden, massive hematochezia and abdominal pain; his hemoglobin dropped from 12 to 8.3. Colonoscopy revealed coagulated blood in a diverticulum, but bleeding recurred after cautery of the lesion.Repeated upper and lower gastrointestinal (GI) endoscopy, visceral selective angiogram, bleeding scan, and Meckel diverticulum scan did not locate the source of bleeding. Further investigation with capsule endoscopy demonstrated two arteriovenous malformations in the small bowel.Wireless capsule endoscopy is a sensitive and specific test for overt obscure gastrointestinal bleeding. Clinicians need not hesitate to employ this procedure when other diagnostic modalities fail.
