Eosinophilic esophagitis is a disease associated with dysphagia and has a seasonal variation in incidence. The primary aim of this study was to search for a potential seasonal variation in the incidence of esophageal foreign bodies or food impaction. In addition, after exclusion of structural or accidental causes, the authors sought to explore if such a variation would differ between patients with or without atopic disorders.
Case series with chart review.
NÄL Medical Centre Hospital, a secondary referral hospital.
A total of 314 consecutive cases of esophageal bolus impaction from 2004 through 2009 were included and analyzed regarding seasonal variation in incidence. The analysis was repeated after exclusion of cases with sharp items, cancer, or atresia and again separately after subdividing this group according to presence of atopy.
The overall incidence of esophageal bolus impaction was significantly higher during summer and fall than during the corresponding winter and spring period. In cases with atopic disorders and soft foods or meat bolus obstruction (n = 90), the incidence during the fall was significantly higher than that during the winter, and the incidence during the summer and fall was significantly higher than the corresponding incidence during the winter and spring. This variation was not present in patients without any signs or symptoms of atopy.
There was a significant seasonal variation in the incidence of acute esophageal bolus impaction. This variation was pronounced in patients with a coexisting atopic diathesis but was nonsignificant in patients without atopy.
嗜酸性粒细胞性食管炎是一种与吞咽困难相关的疾病，其发病率存在季节性变化。本研究的主要目的是寻找食管异物或食物嵌塞发病率的潜在季节性变化。此外，在排除结构或意外原因后，作者试图探讨这种变化是否会在伴有或不伴有特应性疾病的患者之间有所不同。
病例系列，病历回顾。
NÄL 医疗中心医院，一家二级转诊医院。
共纳入了 2004 年至 2009 年期间的 314 例连续食管团块嵌塞病例，并分析了发病率的季节性变化。在排除锐器、癌症或闭锁的病例后，再次进行了分析，并根据特应性的存在将该组病例进一步细分后，再次进行了分析。
食管团块嵌塞的总发病率在夏季和秋季明显高于冬季和春季。在伴有特应性疾病和软食或肉类团块梗阻的病例（n=90）中，秋季的发病率明显高于冬季，夏季和秋季的发病率明显高于冬季和春季的相应发病率。这种变化在没有任何特应性症状的患者中不存在。
急性食管团块嵌塞的发病率存在明显的季节性变化。这种变化在伴有并存特应性体质的患者中更为明显，但在无特应性的患者中则不明显。
