Individualized Treatment of Multiple Magnetic Foreign Body Ingestion in Children

Background: The incidence of multiple magnetic foreign body (MMFB) ingestion in children is rising, which poses a serious risk for gastrointestinal tract injury. In the current study, the clinical characteristics were analyzed to enhance awareness among parents and caregivers, treatment experiences were summarized and discussed, and optimal treatment plans were identified. Methods: A retrospective analysis was performed on 130 pediatric patients with MMFB ingestion at the Children's Hospital Affiliated with Zhejiang University School of Medicine, between June 2016 and June 2023. The clinical data, treatment details, and patient prognosis were systematically collected. Results: Forty-one patients were managed conservatively, while 89 patients underwent open surgery. Among the 44 patients who were treated with laparoscopic surgery, conversion to laparotomy was necessary in 28. The risk of gastrointestinal perforation was higher in symptomatic children than in asymptomatic children (chi-square value: 37.156; P < .001). Perforations were mainly observed in the small intestine. The median length of hospital stay was 10 days in the cohort of 16 children who underwent laparoscopic surgery successfully, which differed from the group of 28 children who were converted to a laparotomy (10 days [interquartile range, or IQR: 9-12.75 days] versus 12 days [IQR: 10-15.75 days]; P < .05). Conclusions: The ingestion of MMFBs in children can lead to severe injuries, underscoring the importance of early detection and treatment. Tailored clinical management strategies should be implemented based on individual conditions, while prompt and effective interventions can minimize harm. Therefore, we propose a comprehensive framework for individualized treatment processes.
