Abstract: Objective In this study, we aim to evaluate the global scientific 
production of Helicobacter Pylori (H. pylori) research, study the characteristics 
of H. pylori research activities, and identify patterns, tendencies, and 
regularities of H. pylori-related articles.
Methods Data were based on the online version of Science Citation Index 
Expanded, from the Web of Science database. Articles referring to H. pylori 
were assessed by the trend of publication output during 1991-2008, and 
analysis of the distribution of words in the article title, author keyword, and 
KeyWords Plus was carried out.
Results Globally, 37451 papers were published during the 18-year study period, 
including 19 080 articles, 10 396 meeting abstracts, 2625 reviews, 1943 
proceedings papers, and 1866 letters. There were totally 1727 journals listed in 
the 122 Science Citation Index subject categories. The mainstream research on 
H. pylori was in the clinical gastroenterology and hepatology, microbiology, and 
pharmacology and pharmacy fields. The G7 industrial countries held the majority 
of total world production. Research on the H. pylori-related topic 'ulcer' 
remained the hotspot of H. pylori research, whereas that on the related topic 
'gastric cancer' increased during the 18-year study period.
Conclusion With synthetic analysis of word in article title, author keyword, and 
KeyWords Plus, it can be concluded that application of H. pylori in clinical 
gastroenterology, especially research related to 'cancer' is the orientation of all 
the H. pylori research in the 21st Century. This bibliometric method can help 
relevant researchers understand the panorama of global H. pylori research, and 
establish the direction of further research. Eur J Gastroenterol Hepatol 23:295-
