ABSTRACT

This article discusses the studies on functional and motor gastrointestinal disorders presented at the 2014 Digestive Diseases Week conference that are of greatest interest to us. New data have been provided on the clinical importance of functional gastrointestinal disorders, with recent prevalence data for irritable bowel syndrome and fecal incontinence. We know more about the pathophysiological mechanisms of the various functional disorders, especially irritable bowel syndrome, which has had the largest number of studies. Thus, we have gained new data on microinflammation, genetics, microbiota, psychological aspects, etc. Symptoms such as abdominal distension have gained interest in the scientific community, both in terms of patients with irritable bowel syndrome and those with constipation. From the diagnostic point of view, the search continues for a biomarker for functional gastrointestinal disorders, especially for irritable bowel syndrome. In the therapeutic area, the importance of diet for these patients (FODMAP, fructans, etc.) is once again confirmed, and data is provided that backs the efficacy of already marketed drugs such as linaclotide, which rule out the use of other drugs such as mesalazine for patients with irritable bowel syndrome. This year, new forms of drug administration have been presented, including metoclopramide nasal sprays and granisetron transdermal patches for patients with gastroparesis. Lastly, a curiosity that caught our attention was the use of a vibrating capsule to stimulate gastrointestinal transit in patients with constipation.
