【摘要】 目的 胃窦毛细血管扩张症（gastric antral vascular ectasia,GAVE）是一种罕见但重要的上消化道出血性疾病，本研究旨在提高临床医生对该病的鉴别和诊治水平。方法 对收治的1例GAVE患者临床资料进行分析，并结合现有文献资料对GAVE的病因、发病机制、诊治方法 进行回顾性综述。结果 老年女性患者，表现为中重度贫血，需反复输血治疗，胃镜下可见典型的“西瓜胃”样表现。结论 氩离子凝固术（argon plasma coagulation,APC）是目前治疗GAVE应用最广泛的临床手段，操作简便、成本较低、安全性高，但往往需多次治疗才能达到临床治愈。更多还原

【Abstract】 Objective Gastric antral vascular ectasia(GAVE)is an uncommon but important upper gastrointestinal bleeding disorder. This study aims to improve clinicians′ ability to distinguish and treat GAVE. Methods We analyzed the clinical data of a patient with GAVE and reviewed the etiology,pathogenesis,diagnosis,and treatment methods of GAVE based on the existing literature data. Results The elderly female patient, characterized endoscopically by watermelon stomach,presented with moderate to severe anemia and required repeated blood transfusions. Conclusion Argon plasma coagulation(APC) is currently the most widely used clinical method for treating GAVE,which has the advantages of low cost,easy operation,and safe,but it often requires multiple treatments to achieve a clinical cure.更多还原
