Introduction
Many studies quantitatively analyzing the academic literature have appeared in the last two years. These bibliometric studies provide the "bestsellers" for the reader. Citation analysis is a commonly used bibliometric method. In spite of the limitations, it remains a good way for measuring the impact an article has on a specific field, specialty or a journal.
Methods
The Thomson Reuters Web of Knowledge was used to list all Bariatric Surgery Related Articles (BSRA) published from The top 100 most cited BSRA in 354 surgical and general journals were selected for further analysis.

CONCLUSIONS
Most of the discoveries and milestones in  Bariatric surgery research have been  included in our bibliometric study.   This could provide a source of great reference and value for young investigators and clinicians. Not surprisingly, newer papers, so called 'rising stars', have not made it into the list. It is also apparent that the number of citations of an article is not related to the level of evidence, this can be supported by the fact that many Level IV articles have made it into the list.
