运用文献计量学方法对CNKI数据库胃肿瘤相关文章进行可视化及热点分析，了解我国胃肿瘤的外科治疗现状及发展趋势，为我国胃肿瘤的治疗与研究提供基础支撑，指导相关医疗政策的制定。

在CNKI数据库中，以"胃癌+胃肿瘤""外科+手术+微创+腹腔镜+治疗+切除术+根治术+根治性切除+淋巴结清扫+淋巴结切除术+机器人"为关键词检索相关文献，筛选并下载文献，以CiteSpace软件为工具，对胃肿瘤治疗相关研究进行文献梳理，对发文作者、研究机构和关键词进行可视化知识图谱分析。

（1）我国胃肿瘤研究机构主要集中在各大医院和各大医学高校研究所，各医院及高校研究所之间联系较少，很多机构缺乏跨机构、跨地域的合作研究，尚未形成稳定的联合研究，缺乏知识共享和机构之间的合作与交流；作者之间联系相对紧密，但未形成明显的核心作者群。（2）手术入路、切除范围、重建方法以及开放手术、腹腔镜手术和机器人手术各自优势、化疗方案等是当前研究的热点，对比国内外治疗方法的优缺点，了解国内外治疗手段的不同，为我国胃肿瘤治疗提供新的思路，让我国在胃肿瘤领域的治疗有了巨大的进展，为患者带来了希望。

基于CiteSpace对胃肿瘤外科治疗文献进行可视化分析发现，当前我国胃肿瘤外科治疗的研究经历了3个阶段，研究数量和质量逐渐增加，并向精准、高效智能方向发展，腹腔镜、机器人和化疗方案是当前的研究热点，并有望在未来继续被视为研究热点。

To visualize and analyze the hot spots of gastric tumor related articles in CNKI database with bibliometric methods, trying to understand the current situation and development trends of surgical treatment of gastric tumor in China, provide basic support for the treatment and research of gastric tumor in China, and to guide the formulation of relevant medical policies.

In the CNKI database, relevant literatures were searched with the keywords of "gastric cancer + gastric tumor" and "operation + surgery + minimally invasive + laparoscopy + treatment + excision + radical dissection + radical resection + lymph node dissection + lymph node resection + robot", screened and downloaded, and CiteSpace software was used as a tool. The literature on gastric tumor treatment was reviewed, and the authors, research institutions and key words were analyzed by visual knowledge graph.

(1) The research institutions were mainly concentrated in major hospitals and major medical university institutes, and there was little contact between hospitals and university institutes. Many institutions lacked cross-institutional and cross-regional cooperation research, had not formed stable joint research, and lacked knowledge sharing, cooperation and communication between institutions. The authors in the field of gastric tumor research in China were relatively closely related, forming a close relationship network. (2) Surgical approach, resection range, reconstruction method, advantages of open surgery, laparoscopic surgery and robotic surgery, and chemotherapy regimen were the hotspots of current research. By comparing the advantages and disadvantages of domestic and foreign treatment methods, it was easy to understand the differences of treatment methods between Chinese and foreign countries, and provide new ideas for the treatment of gastric tumors in China, which has made great progress in the treatment of gastric tumors and brought hope to patients in China.

Based on the visual analysis of literature on surgical treatment of gastric tumors by CiteSpace, it is found that laparoscopy, robotics and chemotherapy are the current research hotspots and are expected to continue to be considered as research hotspots in the future.
