[Functional and motility gastrointestinal disorders].

Abstract

As in previous years, a huge number of studies were presented at the Congress of the American Gastroenterology Association (Digestive Diseases Week [DDW]), some of which were better than others. The present article attempts to extract and summarize the most interesting findings reported. In general terms, certain technological advances have been consolidated, with full incorporation into clinical practice, such as impedancemetry and high-resolution manometry. New physiopathological data are coming to light that increasingly indicate the inextricable link between organic and psychological factors (the biopsychosocial model) in functional gastrointestinal disorders (FGID). Despite the high hopes that the Rome III criteria would improve the diagnosis of FGID and especially that of functional dyspepsia, their practical application has been fairly discouraging. Moreover, at least two studies have demonstrated that these criteria cannot be used to differentiate subtypes of functional dyspepsia and that there is wide overlap with gastroesophageal reflux disease. New data were presented on the role of genetic, microinflammatory and psychological factors in the etiopathogenesis of the two main FGID: functional dyspepsia and irritable bowel syndrome (IBS). The results on the safety and efficacy of acotiamide in functional dyspepsia and of linaclotide and prucalopride in idiopathic and IBS-associated constipation were also presented. Several studies, and even meta-analyses, have demonstrated the utility of biofeedback in the treatment of constipation. Even so, the efficacy of this therapy has been questioned due to certain methodological deficiencies in some studies. In DDW 2011, studies confirming the utility of biofeedback, whether hospital- or home-based were presented, in dyssynergy constipation. The present article also mentions certain features of special interest in the diagnosis and treatment of rumination syndrome, thoracic pain of possible esophageal origin and cannabinoid-induced hyperemesis syndrome.
