Over the past two decades, there has been an impressive increase in the number of bariatric surgeries.

Similarly, several bibliometric studies have reported an upward trend in scientific output.

This study aims to compare these two trends.

In particular, it reveals many similarities in the trend of publications and procedures in bariatric surgery: in particular with a significant growth rate over the last 15 years and the progressive polarization towards two procedures (SG and RYGB). Nevertheless, some important differences persist at the national level.
