钩虫感染在我国南方农村是常见病之一,临床上常见症状有贫血、营养不良、腹痛及胃肠功能紊乱,但钩虫病合并上消化道急性大出血尚少见报导,且在临床工作中往往与溃疡病合并上消化道出血难于鉴别,常常由于误诊,给病者带来不必要的痛苦和负担。 Hookworm infection is one of the common diseases in rural areas of southern China. Common clinical symptoms are anemia, malnutrition, abdominal pain and gastrointestinal disorders. However, it is rare to report that hookworm disease is associated with acute upper gastrointestinal bleeding. In clinical practice, Ulcer disease is difficult to identify upper gastrointestinal bleeding, often misdiagnosis, to patients with unnecessary pain and burden.
