Foreign bodies (FBs) in the digestive tract are common in children, we analyzed the clinical characteristics of children with FBs in the digestive tract and discuss the risk factors for serious complications. We retrospectively reviewed clinical data of 139 children with FBs in the digestive tract. Based on the severity of complications caused by FBs, the patients were divided into risk and general groups for analysis and comparison. Significant differences were observed in the retention sites of FBs, the diameter of FBs retained in the esophagus, FBs retention time exceeding 24 h, and the absence of witnesses between the 2 groups. Inadequate care, button batteries (BBs), ingested mmFBs, FBs retained in the esophagus, long-term retention, and giant gastric bezoars may cause serious complications. In addition to treating FBs and the complications, clinicians should emphasize the importance of childcare to prevent the ingestion of FBs.
