This article discusses the most interesting studies on functional and motility gastrointestinal disorders presented in Digestive Diseases Week (DDW) in 2013. New data were reported on the clinical importance of functional gastrointestinal disorders (FGID) and on how they can produce numerous disturbances such as inflammatory bowel disease. These disturbances are associated with somatic functional disease and particularly with fatigue. In addition, new data have emerged on the physiopathology of these disorders, with some studies reporting that environmental factors and events in early infancy can favor their development. Data were also presented on how bile acids can increase susceptibility to diarrhea in patients with irritable bowel syndrome (IBS) and on how the type of food intake can favor the development of symptoms. More data are available on the presence of underlying celiac disease in patients with IBS, which should prompt us to investigate this disease in our patients. Likewise, indiscriminate application of a gluten-free diet in patients with IBS has been shown not to produce a clear improvement. Regarding the physiopathology of functional dyspepsia (FD), results have been presented on how psychological factors can modify gastric accommodation and how this is in turn related to visceral hypersensitivity and gastric emptying. Regarding therapy, mirtazapine can improve symptoms and lead to weight gain in patients with severe FD and substantial weight loss. Results were presented on new drugs for IBS such as ibodutant and on old drugs with new applications such as mesalazine and ebastine. The antinociceptive effect of linaclotide is now better understood and a meta-analysis has shown its effectiveness in IBS with constipation as the main symptom. In patients with constipation, pelvic floor dysynergy can be diagnosed by a simple clinical interview and rectal touch. More data are available on the efficacy of prucalopride (which has been shown to accelerate colon transit time) and data were provided on plecanatide, a potential new drug that could be useful in constipation. Finally, results were presented on the use of botulinum toxin injection in patients with spastic motility disorders of the esophagus. Also worthy of mention is a study confirming a higher frequency of esophageal cancer patients with achalasia who receive treatment.
