Bibliometric analysis and evaluation of publications on non-<i>Helicobacter pylori helicobacters</i> from 1993 to 2023

<b>Aim:</b> A bibliometric analysis and evaluation of research on non-<i>Helicobacter pylori Helicobacter</i> species (NHPHs) is essential to determining future research directions. <b>Materials &amp; methods:</b> A comprehensive search was carried out using predetermined search terms within the Web of Science Core Collection (WoSCC) to gather publications spanning from 1993 to 2023. VOSviewer and Citespace were employed for data analysis and visualization. <b>Results:</b> 308 publications on NHPHs were included. Among these, gastric NHPHs received more publications and attention compared with enterohepatic NHPHs. Key findings included the identification of most productive countries, institutions, journals, authors, keywords, research trends and notable perspectives in the field. <b>Conclusion:</b> The article guides further research and clinical applications on NHPHs. Previous global research trends in non-<i>Helicobacter pylori</i> <i>Helicobacter</i> species (NHPHs) have focused on population studies and clinical implications. The future research direction of NHPHs lies in exploring the correlation between its biological characteristics and gastrointestinal diseases. The bibliometric analysis of this study may provide a reference for researchers in the same field to add to the body of knowledge a summative review of research in the field of NHPHs and an independent insight into the prediction of future research trends.

**研究目的**：开展非幽门螺杆菌属螺杆菌（non-Helicobacter pylori Helicobacter, NHPH）相关研究的文献计量分析与评价，对于确定该领域未来研究方向至关重要。**材料与方法**：本研究以预设检索式在Web of Science核心合集（Web of Science Core Collection, WoSCC）中开展全面检索，采集1993年至2023年期间发表的相关文献。采用VOSviewer与Citespace两款工具进行数据分析与可视化处理。**研究结果**：本研究共纳入308篇NHPH相关文献。其中，胃部相关NHPH的研究文献数量与关注度均高于肠肝源性NHPH。本研究明确了该领域发文量领先的国家、机构、期刊、作者、关键词、研究趋势及代表性研究视角。**研究结论**：本研究可为NHPH相关的后续研究与临床应用提供指导。既往全球NHPH研究热点集中于人群研究与临床意义探索。NHPH领域未来的研究方向将聚焦于其生物学特性与胃肠道疾病之间的关联分析。本研究的文献计量分析可为同领域研究者提供该领域研究的系统性综述参考，并为未来研究趋势预测提供独到的学术视角，以充实该领域的知识体系。
