Guideline for wireless capsule endoscopy in children and adolescents: A consensus document by the SEGHNP (spanish society for pediatric gastroenterology, hepatology, and nutrition) and the SEPD (spanish society for digestive diseases)

Introduction: Capsule endoscopy (CE) in children has limitations based mainly on age. The objective of this consensus was reviewing the scientific evidence. Material and methods: Some experts from the Spanish Society of Gastroenterology (SEPD) and Spanish Society for Pediatric Gastroenterology, Hepatology, and Nutrition (SEGHNP) were invited to answer different issues about CE in children. These sections were: a) Indications, contraindications and limitations; b) efficacy of CE in different clinical scenarios; c) CE performance; d) CE-related complications; e) Patency capsule; and f) colon capsule endoscopy. They reviewed relevant questions on each topic. Results: The main indication is Crohn’s disease (CD). There is no contraindication for the age and in the event that the patient not to swallow it, it should be administered under deep sedation with endoscopy and specific device. The CE is useful in CD, for the management of OGIB in children and in Peutz-Jeghers syndrome (in this indication has the most effectiveness). The main complication is retention, which should be specially taken into account in cases of CD already diagnosed with malnutrition. A preparation regimen based on a low volume of polyethylene glycol (PEG) the day before plus simethicone on the same day is the best one in terms of cleanliness although does not improve the results of the CE procedure. Conclusions: CE is safe and useful in children. Indications are similar to those of adults, the main one is CD to establish both a diagnosis and disease extension. Moreover, only few limitations are detected in children.
