Abstract：Objective A retrospective study was conducted to investigate the related factors of complications in patients with esophageal foreign bodies (EFBs), and to lower the incidence of complications and improve treatment efficacy. Methods From May 1997 to September 2014, 414 cases with EFBs at our hospital were enrolled in the study group. Using the patients with complications as the subjects and patients with no complications as the controls, a case-control study was designed to compare the differences between their characteristics and treatments. Applying multivariate conditional logistic analysis, we probed the risk factors of complications. Results Of all the 414 cases, 60 (15.0%) individuals appeared esophageal mucosa injury and 22 (5.3%) individuals appeared esophageal perforation. Multivariate conditional logistic analysis indicated that type of EFBs and duration of impaction were associated with complications in patients with EFBs (P＜0.01). Compared to animal bone, date pit was more likely to cause complications (OR=3.016,95%CI=1.578-5.763). It also showed that the interval time from impaction to seeking medical care was the related factor of complications. Patients who saw a doctor after more than 48 hours were more easily to arise complications (OR=2.186,95%CI=1.134-4.213). For subjects, the ratio of surgical treatment was higher than controls (P＜0.01). Compared to controls, subjects improved the feeding (P＜0.05) and shortened the time of length of stays and postoperative recovery by about two days, respectively. Conclusion Patients with EFBs should seek hospital treatment as soon as possible. Clinical doctors should consider various data, especially type of EFBs and interval time. Accurate treatment and selective surgery may prevent serious complications and shorten the time of postoperative recovery and length of stays.
