Functional gastrointestinal (GI) disorders are often associated with intestinal dysmotility representing a diagnostic challenge. A relatively new method is the wireless motility capsule (WMC) test, which continuously measures pH, pressure, temperature and regional transit times as it passes through the GI tract. In adults, the WMC test was approved for use in the diagnosis of gastroparesis and constipation by assessing GI transit and contractility. We performed the WMC test in nine adolescent patients aged 12–17 years with functional GI symptoms from July 2017 until February 2019. Abnormal transit times were detected in four patients. Three patients showed abnormal transit times of the upper GI tract: in two cases, contractility analysis revealed prolonged gastric retention, and in one patient, abnormal colonic transit was detected. Conclusion: The WMC test is a minimally invasive procedure with potential to expand future diagnostic opportunities for paediatric patients with functional GI disorders and suspected motility disturbances. What is Known: • The assessment of GI transit and contractility of the whole gut is possible with the WMC test which is approved for use in the diagnosis of gastroparesis and constipation in adults. What is New: • The WMC test is a non-invasive diagnostic tool with the potential to expand diagnostic opportunities in paediatric patients by assessing regional and whole gut motility. • In paediatric patients with functional GI disorders, the WMC test could help to make an adequate diagnosis and initiate appropriate therapy.
