This edition represents the first edition of the ninth year of Frontline Gastroenterology. We are delighted to have seen the journal become an established fixture in the wide field of GI publications. We hope all previous submitting authors have been equally pleased to have received notification that their manuscripts are now findable on PubMed, and the editorial board look forward to establishing an impact factor as the next stage of the journal’s development. We intend to maintain and enhance the journal’s key selling point, namely being a journal that clinicians turn to for evidence of what is contemporary in best practice. This often means challenging the rituals and orthodox beliefs of what is ‘accepted’ and undertaking changes in practice that help improve care of GI patients – this edition of the journal highlights just such manuscripts.
