A bibliometric analysis of global bariatric surgery research

Objective To explore the future research hotspots and trends of bariatric surgery by bibliometric analysis. Methods All SCI papers related to bariatric surgery included in the Web of Science database from1998 to 2017 were searched,and the average number of papers published per year,the number of papers pages,the number of citations,the number of citations,the number of countries involved in bariatric surgery research,the top 20 journals based on the number of bariatric surgery related papers,and the top 37 keywords with the cumulative number of occurrences were comprehensively analyzed. Results A total of19 307 citations related to bariatric surgery were retrieved. The cumulative number of publications on bariatric surgery has increased exponentially since 2003. The journals with the top2 publications accounted for 33.64% of all published papers. Changes in the frequency of occurrence of keywords might reveal changes in research hotspots in this field. Conclusion Sleeve gastrectomy and potential mechanism responsible for weight loss and metabolic disorders will undoubtedly remain the hotspots of bariatric surgery research in the next few decades.
