[Gastroenterology and hepatology in 2016].

This article aims to detail the major innovations occurred in Gastro-enterology in 2016, including the introduction of a new molecule, the vonoprazan, for the treatment of refractory gastroesophagal reflux disease (GERD) and a new way of eradication of H. pylori. The possibility to use an intermittent dose of PPI rather than continuously in severe gastric and duodenal ulcers after successful endoscopic hemostasis is also discussed as well as the withdrawal of corticosteroids in the treatment of autoimmune pancreatitis. The formulation of corticosteroids in the treatment of eosinophilic esophagitis, the interest of the chromo-endoscopy during colonoscopy highlighting small polyps (from 1 to 5 mm = « diminutive polyps ») and the introduction on the Swiss market for biosimilars in the treatment of inflammatory bowel disease (IBD) are also discussed.
