Summary
Research on laparoscopic digestive surgery surged between 1991-1996, with the USA leading production. However, high-quality studies, such as random clinical trials, were notably scarce.
Area of Science:
- Laparoscopic digestive surgery research
- Bibliometric analysis
Background:
- Laparoscopic digestive surgery emerged as a significant field between 1991 and 1996.
- Understanding research trends and publication patterns is crucial for scientific advancement.
Purpose of the Study:
- To analyze the production and publication trends in laparoscopic digestive surgery from 1991 to 1996.
- To identify key producing countries, influential journals, and research methodologies.
Main Methods:
- Bibliometric analysis using Medline and Science Citation Index.
- Random sampling with a 99% confidence level for specific data extraction.
- Analysis of publication types, producing/publishing countries, journal impact factors, and study methodologies.
Main Results:
- A total of 4825 publications in laparoscopic digestive surgery were identified.
- The USA was the leading producing country (45%), followed by France, the UK, and Germany.
- The New England Journal of Medicine had the highest impact factor; however, random clinical trials constituted only 1% of the studies, with a focus on techniques, indications, and the gallbladder region.
Conclusions:
- The USA dominated research output in laparoscopic digestive surgery during the study period.
- Despite high publication volume, rigorous study designs like random clinical trials were underrepresented.
- Further emphasis on high-level evidence is needed to advance the field.
