Tremendous progress has been made in the field of lateral lymph nodes (LLNs) in rectal cancer, but no bibliometric analysis in this field has been carried out and published. To reveal the current status and trends in LLNs in rectal cancer, this bibliometric analysis was performed. Cooperation network, co-citation and keyword co-occurrence analyses were conducted. Annual publication, cooperation relationships among authors, institutions and countries, co-cited journal, co-cited author, co-cited reference and keywords were the main outcomes. A total of 345 studies were included in this bibliometric analysis. The number of articles published in this field has been increasing year by year. The authors, institutions and countries worked closely together in this field. Japan has the largest number of published articles, accounting for 51.59% of the total publications. (30 papers, 8.70%) published the most papers in this field. The JCOG0212 trial was the most cited article. Preoperative chemoradiotherapy, multicenter, lateral lymph node dissection (LLND) and metastasis are recent hot keywords, and LLND had the highest burst strength. In conclusion, this bibliometric analysis found that Japanese institutions and authors dominated the field of LLNs in rectal cancer. The JCOG0212 trial was the most influential article, which had a significant impact on the development of guidelines. LLND is a hotspot in this field with the highest burst strength. Further prospective studies are needed in this field.
直肠癌侧方淋巴结（LLNs）领域已取得巨大进展，但该领域尚未进行文献计量分析并发表。为揭示直肠癌LLNs的现状和趋势，进行了本次文献计量分析。开展了合作网络、共被引和关键词共现分析。年度发表情况、作者、机构和国家之间的合作关系、共被引期刊、共被引作者、共被引参考文献和关键词是主要成果。本次文献计量分析共纳入345项研究。该领域发表的文章数量逐年增加。作者、机构和国家在该领域紧密合作。日本发表的文章数量最多，占总出版物的51.59%。（30篇论文，8.70%）在该领域发表的论文最多。JCOG0212试验是被引用最多的文章。术前放化疗、多中心、侧方淋巴结清扫（LLND）和转移是近期的热门关键词，且LLND的爆发强度最高。总之，本次文献计量分析发现日本机构和作者在直肠癌LLNs领域占据主导地位。JCOG0212试验是最具影响力的文章，对指南的制定产生了重大影响。LLND是该领域爆发强度最高的热点。该领域需要进一步开展前瞻性研究。
