Iron deficiency anemia is a common symptom of chronic occult gastrointestinal bleeding. There are numerous potential sources of gastrointestinal hemorrhage, most of which can be detected with the aid of endoscopy of the upper and lower digestive tract. Diagnostic procedures for the small bowel are less sensitive and usually more invasive. On the basis of the relevance of information they provide, the various diagnostic procedures and their indication in the diagnosis of iron deficiency anemia are critically reviewed, and a systematic diagnostic strategy developed.
缺铁性贫血是慢性隐匿性胃肠道出血的常见症状。胃肠道出血有许多潜在来源，其中大多数可借助上、下消化道内镜检查来发现。小肠的诊断程序敏感性较低且通常侵入性更强。基于它们所提供信息的相关性，对各种诊断程序及其在缺铁性贫血诊断中的适应证进行了严格审查，并制定了系统的诊断策略。
