title: [Functional and motility gastrointestinal disorders].
abstract: We summarize and discuss the studies presented at the congress of the American Association of Gastroenterology (Digestive Disease Week) that, in our opinion, are of greatest interest. Both clinically and physiopathologically, functional gastrointestinal (GI) disorders are highly complex. A single cause is unlikely to explain symptoms as heterogeneous as those of functional dyspepsia and irritable bowel syndrome (IBS). Therefore, it is easier (and more useful) to try to understand functional GI disorders using a bio-psycho-social model. Moreover, data supporting the combined importance of genetic, organic and psychological factors in the onset and persistence of functional GI disorders are increasingly convincing. This year, new data have been provided on pharmacogenetics in gastroparesis, on microinflammation or alterations in the modulation of somatic and visceral sensitivity in functional dyspepsia, and on the impact of psychological factors in IBS. From the therapeutic point of view, further information has been provided on the role of probiotics, the antinociceptive effect of linaclotide (demonstrated in several studies presented this year), and on the high efficacy of hypnotherapy in patients with IBS. Finally, data on the clinical management of patients with constipation due to pelvic floor dyssynergia and on the safety and efficacy of prucalopride in patients with severe constipation were also of interest.
