Objective: This study aimed to assess the utility of magnetically controlled capsule endoscopy (MCE) in the diagnosis of pediatric gastrointestinal diseases.
Methods: A retrospective cohort study was conducted, which collected data from 1040 children (546 males and 494 females; mean age: 11.0 ± 2.6 years) who underwent MCE at Shanghai Children's Hospital between June 2017 and February 2023. Information on gastric visualization, cleanliness, examination times, lesion detection rates, and other parameters were recorded. A 2-week follow-up monitored capsule excretion and adverse reactions.
Results: Of the 1055 patients, 78 had difficulty swallowing the capsule, and 15 could not swallow even with assistance, which led to their exclusion. The small intestine was successfully examined in 94.5% (206 out of 218) of the 218 children who were able to proceed with the procedure. The remaining 822 underwent esophagus and stomach examinations. The average transit time of the endoscopy capsule in the esophagus, stomach, and small intestine was 5 (3, 9) s, 57.0 (29.0, 102.0) min, and 306.0 (234.0, 500.0) min. In the examined cases, complete small bowel visualization was achieved in 94.5% of the patients. The most common symptoms reported by the patients were abdominal pain (77.9%) and nausea with vomiting (13.5%). Lesion detection rates were 38.8% in the stomach, 21.1% in the duodenum, and 43.1% in the jejunoileum. No complications, such as capsule retention or intestinal obstruction, were observed.
Conclusion: MCE is a feasible and safe method for examining the gastric cavity and small bowel in pediatric patients.
