Abstract:
Objective:To clarify the feasibility and safety of magnetically guided capsule endoscopy (MGCE) in minors.
Methods:A descriptive cohort study was carried out to retrospectively collect the data of minors (<18 years) who underwent MGCE in Ruijin Hospital from April 2015 to October 2018. Exclusion criteria: patients with dysphagia, obvious gastrointestinal bleeding, diagnosed or suspected gastrointestinal obstruction, or congenital gastrointestinal malformations or intestinal fistula; patients with previous bowel surgery, or in poor general condition; patients with implants; pregnant patients; patients with incomplete data or without data. A total of 218 patients, including 122 males and 96 females, with mean age of (12.0±3.1) (5-17) years and 236 times of examination were included. The capsule size of the Ankon MGCE system was 11.8 mm×27 mm, taking two pictures per second, with a viewing angle of 140 degrees. Data of gastric visualization (0% to 100%), gastric cleanliness (satisfactory cleanliness was defined as a clear display of the gastric mucosa; the effect of bubbles or mucus on the visual field was negligible, or the gastric mucosa was slightly blurred; a small amount of air bubbles or mucus affected slightly the field of view), gastric or small bowel examination time, lesion detection rate, etc. were recorded. All the patients were followed up for 2 weeks to confirm capsule excretion and to record adverse events.
Results:A total of 202 patients (217 times) completed gastric examination and 112 patients (125 times) completed small bowel examination. The median gastric visualization of cardia, fundus, body, angulus, antrum and pylorus was 100%, 90% (75%,100%), 100% (80%,100%), 100%, 100%, and 100%, respectively. The cleanliness of the gastric cardia, fundus, body, angle, antrum, and pylorus was assessed to be satisfactory in 100.0%, 76.5% (153/200), 92.5% (185/200), 97.5% (195/200), 99.5% (199/200), and 100.0% of patients, respectively. In 202 patients undergoing gastric examination, the median gastric exanimation time was 10.5 (7.3, 13.9) minutes. In 112 patients undergoing small bowel examination, the median gastric transit time was 51.5 (20.6, 112.0) minutes and the median small bowel transit time was 232.4 (181.8, 321.6) minutes. The small bowel transit rate was 91.1% (102/112). The lesion detection rates of stomach, duodenum and jejunoileum were 18.8% (38/202), 8.1% (10/124) and 26.8% (30/112) respectively. No complications or adverse events occurred.
Conclusion:MGCE is feasible and safe to detect both gastric cavity and small bowel in minors.
