Author´s reply: "Consensus document for Digestive services in the National Health System of the XXI century".

We would like to thank the Board of Directors of the Spanish Association of Digestive Ultrasound (AEED) for their interest in our paper. We agree with them about the relevance of digestive ultrasound in the management of patients with a digestive pathology. In our article, we stated as follows: "These standards do not include all digestive units, processes and procedures within the scope of gastroenterology and hepatology. This report is focused on the most relevant quality standards or those with available standards developed by other national or international scientific-medical societies. The process of developing standards for UD units, processes and procedures must be progressive, based on the scientific evidence available at the time. The scope of these standards will also be extended to a greater number of monographic units, processes and procedures."
