基于CiteSpace的食管癌术后患者早期口服营养研究热点的可视化分析

Visual analysis of early oral nutrition research hotspots in postoperative patients with esophageal cancer based on CiteSpace

目的基于Web of Science中食管癌术后患者早期口服营养的相关文献,了解该领域的研究现状和热点。方法在Web of Science检索有关食管癌术后患者早期口服营养的相关文献,检索时限为2012年9月至2022年9月。使用CiteSpace对文献年度发文量、发文作者及国家分布、引文分析、关键词共现、关键词聚类及关键词突现等进行分析。结果2012—2022年共发表食管癌术后早期口服营养相关文献113篇,发文量总体呈上升趋势,发文量最多的前5个国家是日本、中国、美国、新西兰及英国。关键词共现及聚类分析得出3个维度的研究热点:早期口服营养的安全性研究、早期口服营养的疗效性研究及早期口服营养在加速康复中的应用研究。关键词突现揭示营养管理是未来的研究趋势。结论食管癌术后患者早期口服营养研究目前处于实践探索阶段并持续受到关注,未来需加强地域及作者间的合作。推动制订标准化、规范化的早期口服营养管理策略,探索早期口服营养策略在营养管理中的作用可成为未来的研究趋势。

Objective To understand the current research status and hotspots in this field based on the literature on early oral nutrition for postoperative patients with esophageal cancer in Web of Science.Methods The literature on early oral nutrition for postoperative patients with esophageal cancer was searched on Web of Science from September 2012 to September 2022,and the annual number of articles,distribution of authors and countries,citation analysis,keyword co-occurrence,keyword clustering and keyword emergence were analysed using CiteSpace.Results From 2012 to 2022,a total of 113 articles related to early oral nutrition after esophageal cancer surgery were published,with an overall upward trend in the number of publications,and the top five countries with the largest number of publications were Japan,China,the United States,New Zealand and the United Kingdom.The co-occurrence analysis of keywords and cluster analysis revealed three research hotspots:the safety research of early oral nutrition,the curative effect research of early oral nutrition,and the application research of early oral nutrition in accelerated recovery.Keyword emergence reveals that nutritional management was a future research trend.Conclusions Early oral nutrition research in postoperative patients with esophageal cancer is currently in the stage of practical exploration and continues to receive attention.In the future,cooperation between regions and authors needs to be strengthened.Promoting the development of standardized and normalized early oral nutrition management strategies and exploring the role of early oral nutrition strategies in nutrition management can become a research trend in the future.
