Research and Publication Trends in Pediatric Surgery in Latin America: A Bibliometric and Visual Analysis from 2012 to 2021.

INTRODUCTION

Pediatric surgery is a developing specialty with increasing volume in Latin America. However, the research and scientific activity trends carried out in this region in recent years are unknown. This study aimed to analyze and visualize Latin American research in pediatric surgery from 2012 to 2021.

MATERIAL AND METHODS

Bibliometric cross-sectional study of scientific articles on pediatric surgery published by Latin American authors from 2012 to 2021 in Scopus was performed. Statistical and visual analysis was performed with R programming language and VOS viewer.

RESULTS

449 articles were found. Observational studies (44.7%; n = 201), case reports (20.4%; n = 92) and narrative reviews (11.4%; n = 51) were found to be the most common study designs. The published articles were predominantly monocentric (73.1%; n = 328), only 17% (n = 76) involved authors from 2 or more countries, and mostly there was no collaboration with high-income countries (80.6%; n = 362). The Journal of Pediatric Surgery was the journal with the highest volume of articles published (n = 37). The most used terms were Laparoscopy, Complications, and Liver Transplantation, and the countries with the highest number of articles published were Brazil and Argentina.

CONCLUSIONS

This study found a progressive increase in the scientific activity of Latin authors in pediatric surgery from 2012 to 2021. The evidence produced was mainly from observational studies and case reports, predominantly conducted in Brazil. Multinational and international collaboration was low; the most frequent topics of interest were laparoscopy and minimally invasive surgery.
