The goals of scientific publishing – to advance our knowledge of disease mechanisms and treatments – sometimes come into conflict with the professional and personal benefits of publishing. Authors may feel pressure to publish as many scientific articles as possible to advance their careers and reputations. It is the role of journal editors to ensure that scientific articles minimize this conflict by ensuring that each provides a “substantial new contribution to their field.”[1]

In this article, we present the second part of an ongoing series focused on ethical principles in publication in the field of gastroenterological endoscopy [2] [3]. We review what constitutes duplicate publication, “salami slicing,” and ethical concerns in large multicenter retrospective case series.
