Hemorrhage from Extra-Antral Gastric Antral Vascular Ectasia in a Patient with Duodenal Heterotopic Gastric Mucosa.

摘要: Gastric antral vascular ectasias (GAVE) have been increasingly recognized as an uncommon cause of chronic gastrointestinal bleeding and anemia, although their underlying pathogenesis is not completely well understood. Heterotopic gastric mucosa (HGM) has reported to occur at various sites along the tract relatively common, it often asymptomatic. We report a case 60-year-old woman with prior history GAVE who developed melena symptomatic anemia during her hospitalization following cardiac catheterization. Initial EGD demonstrated nonbleeding newly discovered duodenal mass. Duodenal mass biopsies were ultimately notable for HGM histologic features extra-antral GAVE. The patient required blood transfusions consequently had small bowel endoscopy fresh in proximal bowel. underwent push enteroscopy which active overlying oozing GAVE, was cauterized Argon-Plasma Coagulation adequate hemostasis. present first time novel association between HGM. Our illustrates that may duodenum. explore potential mechanisms by be involved
