Visual analysis of early oral nutrition research hotspots in postoperative patients with esophageal cancer based on CiteSpace / 中国实用护理杂志

ABSTRACT

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.
