Trastornos funcionales y motores digestivos

Abstract

This article discusses the most interesting presentations at Digestive Disease Week, held in San Diego, in the field of functional and motor gastrointestinal disorders. One of the most important contributions was undoubtedly the presentation of the new Rome IV diagnostic criteria for functional gastrointestinal disorders. We therefore devote some space in this article to explaining these new criteria in the most common functional disorders. In fact, there has already been discussion of data comparing Rome IV and Rome III criteria in the diagnosis of irritable bowel syndrome, confirming that the new criteria are somewhat more restrictive. From the physiopathological point of view, several studies have shown that the aggregation of physiopathological alterations increases symptom severity in distinct functional disorders. From the therapeutic point of view, more data were presented on the efficacy of acotiamide and its mechanisms of action in functional dyspepsia, the safety and efficacy of domperidone in patients with gastroparesis, and the efficacy of linaclotide both in irritable bowel syndrome and constipation. In irritable bowel syndrome, more data have come to light on the favourable results of a low FODMAP diet, with emphasis on its role in modifying the microbiota. Finally, long-term efficacy data were presented on the distinct treatment options in achalasia.
