SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

Online features include full text of all articles, video and audio clips, and MEDLINE links to related articles. Category 1 CME credit can be earned by reading the text material and taking the CME examination online. Gastrointestinal Endoscopy has become the international forum for the newest developments in the specialty, bringing readers challenging reports from leading authorities throughout the world. The journal regularly publishes abstracts of important articles from other leading clinical publications, complete with commentaries from a panel of experts.
Aim: Gastrointestinal Endoscopy will be the preeminent advocate for the science and practice of endoscopy in the world. We will provide the highest quality endoscopic information at the point of care and at the cutting edge of science. We will continue to seek out and publish the best original articles, editorials and reviews as well as exciting new techniques, video cases and society guidelines.
Scope: Gastrointestinal Endoscopy is truly integrated into nearly all aspects of gastroenterology and hepatology as well as diseases and organs accessed via the GI tract. As such, we will review and publish articles not just studies directly involving endoscopy, but also conditions broadly relevant to the GIH community where endoscopy may play a role including inflammatory bowel disease, functional GI diseases and obesity.
