Abstract
Background Henoch–Schönlein purpura (HSP) is a systemic small-vessel vasculitis that commonly affects gastrointestinal tract. The video capsule endoscopy (VCE) characteristics of pediatric HSP patients were rarely investigated. Methods Patients diagnosed with HSP by VCE examination at our hospital from February 2010 to January 2019 are analyzed. The clinical features, laboratory findings, and the characteristics of VCE findings are studied. Results There are 30 patients enrolled in this investigation from February 2010 to January 2020. The mean age of these patients is 96.9±35.8 months, and the most frequent finding of VCE is mucosal erosion, which account for 69 % of the patients, and followed by mucosal erythema or petechia accounted for 79.3 % of the patients. Regarding to the disease location detected by endoscopy, jejunum is the most common involved part of the gastrointestinal tract in pediatric HSP patients. All the patients had jejunum involved except in one patient the VCE did not pass through the pylorus. One third of the patients involved the descent part of duodenum. No side effects are observed in this study. Conclusions VCE is safe and effective in the diagnosis of gastrointestinal involved HSP patients with or without typical skin purpura. Jejunum is the most common involve location in gastrointestinal.
