On behalf of the ESPGHAN we are delighted to present you the app of the 50th Annual Congress of ESPGHAN to be held from Wednesday 10 to Saturday 13 May 2017, in Prague, Czech Republic. The Congress will present a very attractive Scientific Programme of high quality, preceded by comprehensive Postgraduate Courses for Physicians and for Allied Health Care Professionals as well as an additional Course focussing on Paediatric Inflammatory Bowel Diseases. Once again we plan to offer a hands-on Learning Zone on endoscopic and this year also on motility techniques. Last but not least, the congress offers a great platform to meet colleagues in your field from around the world during the meeting and during outstanding social events that should not be missed. We look forward to welcoming you in Prague and trust you will find your participation in the 50th ESPGHAN annual meeting fruitful and enjoyable.
