Management of magnetic foreign body ingestion in children.

ABSTRACT Magnetic foreign bodies ingestion is a special cause for attending emergency department. Here, we aim to analyze the characteristics and treatments of children who ingested magnetic foreign bodies (Buckyballs). Data were collected from children who ingested Buckyballs between February 2017 and October 2019. A retrospective analysis was performed to summarize the experiences of conservative treatment, gastroscopy and surgery when dealing with Buckyballs ingestion.A total of 49 patients with buckyballs ingestion were identified, of whom 11 underwent conservative treatments, 6 underwent gastroscopy, and 32 underwent surgery. Among such individuals, eight patients (72.7%) had a successful conservative treatment (number of Buckyballs [NB]: 3.5[IQR: 2.0-4.0]); four patients (66.7%) had Buckyballs successfully removed by gastroscopy (NB: 3.5[IQR: 3.0-5.5]); 16 asymptomatic (50%) patients (NB: 4.0[IQR: 3.0-8.0]) and 16 symptomatic (50%) patients (NB: 8.5 [IQR: 6.25-11.75]) received emergency surgery. Compared to patients who received conservative treatment, the number of ingested Buckyballs was significantly higher in patients who received surgery or gastroscopy (7.0 [IQR: 3.0-10.75] vs 3.5 [IQR: 2.0-4.0], P < .05). The risk of intestinal perforation was significantly higher in symptomatic patients (P < .05) compared to asymptomatic patients.Gastroscopy is recommended when Buckyballs are in the stomach or esophagus. In asymptomatic patients, conservative treatment can be considered for 4 to 6 days. Patients failing conservative treatment, or those who are symptomatic should undergo emergency surgery.
