A growing body of evidence sug-gests that serrated polyps — once thought to be relatively innocuous — may be precursors of CRC that develop via the serrated pathway. Data supporting this were presented at UEG Week 2015 from a study in which epigenetic and genetic analyses were performed on samples of sessile serrated adenoma/polyp (SSA/P), traditional serrated adenoma, and high-methylation CRCs (Abstract OP174). The aim was to explore the involvement of molecular alterations in the serrated pathway. The study demonstrated that SSA/P samples were highly methylated and repre-sented precursors of high-methylation CRCs with BRAF mutation. A second study, based on the optical diagnostic abilities of endoscopists working in routine practice, emphasized the need for practical, validated classification systems to facilitate the endoscopic differentiation of adenomas, hyper-plastic polyps, and SSA/P (Abstract OP322). The prospective study showed that of 360 optically diag-nosed SSA/P, only 36% were accu-rately characterized. This figure fell to 25% for polyps 1–5 mm in size. Advances in Neurogastroenterology and Motility Professor Magnus Simrén University of Gothenburg Gothenburg, Sweden New therapies in neurogastroenterol-ogy and motility are welcome since these areas affect many patients, but have few available treatment options. Data presented at UEG Week 2015 showed how prucalopride, a selective 5-HT4 receptor agonist, significantly enhances gastric emptying time and improves both symptoms and quality of life in patients with gastroparesis, compared with placebo (Abstract LB5641). The peripherally-acting μ-opioid receptor antagonist, naloxe-gol, was approved by the EMA in 2014 and data were presented on its mode of action and efficacy for the treatment of opioid-induced constipation and non-cancer pain (Abstract OP057). Fascinating new evidence was presented of a beneficial effect of the probiotic, Bifidobacterium longum, on comorbid depression and brain emotional reactivity in patients with IBS (Abstract OP162). Data from a randomized, placebo-controlled study also provided the first such evidence that a low FODMAP diet improves IBS symptoms (Abstract OP163). In addi-tion, there were further phase III data showing the efficacy of eluxadoline in managing symptoms and quality of life in patients with IBS and diarrhea (Ab-stracts OP166, OP167 and OP168).
