The diagnostic value of video capsule endoscopy for Meckel's diverticulum in children.

Background: Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is also an important cause of bloody stool and anemia in children. However, there are few data about video capsule endoscopy (VCE) for MD in children. This study aimed to evaluate the diagnostic value of VCE for MD in children.

Materials And Methods: children who underwent VCE for obscure gastrointestinal bleeding from October 1st 2015 to August 31st 2019 at the Children's Hospital of Fudan University were included in this retrospective study. Medical data, VCE data and Meckel's scans, etc. were collected for each patient.

Results: sixteen patients were diagnosed with MD by VCE, including 13 males and 3 females. The age of the patients ranged from 4 years to 13 years, with an average of 7.8 ± 2.7 years. Lower gastrointestinal tract bleeding was the main symptom for patients with MD, including hematochezia (75 %) and melena (25 %). Of the VCE findings, 14 patients had double lumen signs and 2 showed protruding lesions. Among the 16 patients diagnosed with MD by VCE, 14 patients were diagnosed with MD by Meckel's scan, 3 with MD by abdominal enhanced CT and 14 patients were diagnosed with MD by surgery. During the follow-up, bleeding occurred sporadically in patient 12 and the reason is still unknown.

Conclusions: VCE is useful for the diagnosis of MD and should be used as a valuable and less invasive examination to confirm or establish a diagnosis.
