Abstract:OBJECTIVE To conclude the clinical characteristics of esophageal foreign bodies and explore the potential risk fac⁃ tors for the complications of the esophageal foreign bodies. METHODS The characteristics of cases of esophageal foreign bodies diag⁃ nosed in the Department of Gastroenterology of Children’s Hospital of Fudan University from January 1, 2013 to April 1, 2018 were retrospectively analyzed. According to the endoscopic diagnosis, the children were divided into complications group and no complica⁃ tions group, and the risk factors for complications were analyzed. RESULTS A total of 88 cases of esophageal foreign body with the age of 0.4~13.1 were recruited, including 54 males (61.4%). Age distribution of foreign bodies in the esophagus of boys and girls was not statistically significant (P=0.964). The main type of esophageal foreign body was coin, accounting for 47.7%. The detained position of foreign body was mainly at the upper part of the esophagus, accounting for 63.6%. 18 cases had foreign body related com⁃ plications of which esophagus ulcer was the most common (10/18). Foreign body was independent risk factor for the complications of esophageal foreign bodies, OR=2.02. The successful rate of taking out foreign body in esophagus by electronic gastroscope was 97.7% (86/88), the average time of removing foreign body was (116.2±83.4) seconds. CONCLUSION The type of esophageal foreign body was related to the complications for esophageal foreign bodies.
