To study the clinical characteristics of children swallowing magnetic digestive tract foreign bodies by mistake and analyze the risk factors, so as to seek effective preventive measures and optimize the treatment plan.

Retrospective analysis was performed on the case data of children hospitalized for swallowing magnetic foreign bodies by mistake in Xi 'an Children's Hospital from January 2015 to December 2021.

Among the 153 cases of children who mistakenly swallowed magnetic foreign bodies, most of them were male (68.6%), mostly in early childhood and early school age, and the age fluctuated from 6 months to 14 years old.The number of hospitalizations and the number of surgical operations showed an increasing trend year by year.The number of mistakenly swallowed magnetic foreign bodies varied (1-60), and the types of foreign bodies were different. 85% of patients mistakenly swallowed multiple magnetic foreign bodies or magnetic foreign bodies combined with metal foreign bodies.Eighty-five patients(55.6%) underwent surgical intervention, and the main clinical symptoms were abdominal pain, among which 81 patients had digestive tract fistula, and entero-enteric fistula was the most common (50.6%). compared with the low age group, the OR value of complications in the high age group was 2.280 (95%CI: 1.155-4.501); Compared with other types of foreign bodies, the OR of buckball complications caused by swallowing magnetic beads by mistake was 30.816(95%CI: 7.291-130.254). The presence of clinical symptoms and the time of treatment >1 day significantly increased the risk of complications (P<0.05).

Swallowing magnetic foreign bodies can easily cause serious complications such as digestive tract perforation, thus early detection, diagnosis and treatment are particularly important. Emergency gastroscopy within 24 hours after misingestion is the preferred treatment. If the location of magnetic foreign bodies on X-ray is not moved after multiple dynamic monitoring for more than 24 hours, surgery should be performed in time if there are clinical symptoms.In addition, comprehensive preventive measures should also be taken by age group and multiple parties to reduce the incidence.
