Evolution of research in hernia repair materials: A 20-year bibliometric and visualization study

Hernia repair is a prevalent surgical procedure globally, with increasing demand due to factors such as aging populations, obesity, and previous surgeries. The evolution of hernia repair materials and techniques has significantly impacted surgical outcomes, with advancements focusing on reducing recurrence rates and complications. This study aims to provide a comprehensive bibliometric analysis of research trends in hernia repair materials from 2004 to 2024.

Data were collected from the Web of Science database to quantitatively assess publication trends, influential authors, journals, and collaborative networks. Bibliometric tools such as VOSviewer and CiteSpace were used to analyze keyword co-occurrence, research hotspots, and the evolution of study themes. The analysis focused on the progression from synthetic to biological and composite meshes, alongside the development of minimally invasive techniques.

The study revealed a steady increase in research output, peaking in 2020, with the United States leading in innovation. Initial research focused on synthetic meshes such as polypropylene; however, recent trends include the exploration of biological, composite, and absorbable materials. Advances in laparoscopic and robotic-assisted surgeries were also prominent, reflecting a shift toward patient-centered approaches. Emerging technologies such as nanotechnology and 3D-printed meshes were identified as promising future directions.

This bibliometric analysis demonstrates the evolution and diversification of hernia repair materials and techniques, emphasizing the need for continued innovation. Future research should focus on optimizing patient outcomes through advanced technologies such as tissue engineering and nanotechnology, which have the potential to overcome existing limitations and enhance clinical efficacy.
