The incidence of anemia in 259 patients with a diaphragmatic hernia large enough to be seen on a routine chest roentgenogram was compared with that in 259 age- and sex-matched controls. Eighteen patients with diaphragmatic hernia were anemic, compared to one control subject (P less than 0.001). In thirteen patients with diaphragmatic hernia and in one control the anemia was proven to be caused by iron deficiency. The findings provide additional evidence that a large diaphragmatic hernia can cause anemia secondary to chronic gastrointestinal blood loss, which is usually not the result of reflux esophagitis.
将259例患有大到能在常规胸部X线片上显影的膈疝患者的贫血发生率，与259例年龄和性别匹配的对照者进行了比较。18例膈疝患者出现贫血，而对照者中只有1例（P<0.001）。在13例膈疝患者和1例对照者中，贫血被证实是由缺铁引起的。这些发现进一步证明，大的膈疝可导致继发于慢性胃肠道失血的贫血，而这通常不是反流性食管炎的结果。
