Abstract: 　Objective　To explore the risk factors of complications of esophageal foreign body in children. Methods　The clinical data of 126 children with diagnosed esophageal foreign body who received endoscopic foreign body removal were analyzed retrospectively. Results　Among the 126 patients, 82 were boys and 44 were girls, with a median age of 2.5 years (1 month to 16 years). A total of 95 cases (75.4%) suffered from esophageal mucosal injury, esophageal inflammation and esophageal perforation. Logistic regression analysis showed that age, time of foreign body incarceration and type of foreign body incarceration were the influencing factors for the occurrence of complications of esophageal foreign body (P<0.05). The older the age, the lower the risk of complications (OR=0.21, 95%CI: 0.09~0.48). The longer the time of foreign body impaction (OR=2.12, 95%CI: 1.01~4.45), the greater the risk of complications. When the foreign body type was long/sharp (OR=23.22, 95%CI: 2.03~266.21), the risk of complications increased. Conclusions　The risk of complications caused by incarceration of esophageal foreign bodies in children is high. Medical intervention should be taken as soon as possible to remove incarcerated foreign bodies and reduce complications.
