International publication trends in hepato-pancreato-biliary surgery: emergency compared to oncology

BACKGROUND

There is growing interest in publishing trends given the increasing amount of research publication across various specialities. Studies relating to hepato-pancreato-biliary (HPB) surgery show an oncological focus compared to benign, emergency and trauma.

METHODS

Analysis of ISI JCR impact factors in the Web of Knowledge and the Scimago Journal Rank through Scopus was performed to select four readily available, relevant and frequently read journals from the surgery category. A total of 5265 articles between 2012 and 2016 were categorized relating to emergency or oncology topics. A secondary analysis of PubMed MeSH term was performed to scrutinize trends of publishing over the period 1960-2016.

RESULTS

Of the 5265 articles screened, 2062 related to HPB surgery. Of these, 49% (1007 of 2062) were oncology related. This trend towards oncology-related topics is continued in HPB subspecialty journals where 51% (679 of 1320) of articles are oncology related. Emergency- and trauma-related topics accounted 10% (198 of 2062) overall, whereas in subspecialty journals, they account for 8% (111 of 1320). Secondary analysis of MeSH term trends demonstrated a now stable trend over the last 20 years of liver and pancreatic trauma to oncology ratio of 1:10 publications, and biliary trauma to oncology publishing ratio of 1:5.

CONCLUSIONS

Quantitatively oncology topics are published favourably, whereas emergency- and trauma-related HPB articles appear static. This is in keeping with baseline trends over the last five decades. Further analysis could delineate whether publishing in trauma subspecialty journals compensate for this trend.
