摘要

Robot-assisted colectomy has attracted increasing attention within minimally invasive colorectal surgery, yet its global research landscape has not been systematically characterized. This study aimed to analyze publication trends, collaboration patterns, citation structures, and thematic evolution in robot-assisted colectomy research using bibliometric and visualization methods. Publications indexed in the Web of Science Core Collection (Science Citation Index Expanded) from January 1, 2002, to December 31, 2025, were retrieved on March 30, 2026. Following stepwise database-level filtering, 421 English-language articles and reviews were included. Bibliometrix, VOSviewer, CiteSpace, and Scimago Graphica were used to evaluate annual publication and citation trends, country and institutional contributions, collaboration networks, influential references, and keyword hotspots. Publication output and citation activity increased overall during the study period, with more evident growth from the mid-2010s onward. The United States ranked first in both publication output and citation impact, while Italy also emerged as a major contributor. Assistance Publique Hôpitaux Paris, the University of Milan, and George Washington University were among the most productive institutions. The literature was concentrated in journals related to minimally invasive surgery, colorectal surgery, and robotic surgery. Keyword co-occurrence, clustering, burst, and timeline analyses suggested that research attention has extended from early technical introduction and operative experience toward procedure-specific refinement and outcome-related evaluation, particularly in relation to right colectomy, intracorporeal anastomosis, complete mesocolic excision, central vascular ligation, quality, risk, and short-term outcomes. Overall, this study maps the global knowledge structure and thematic development of robot-assisted colectomy research and suggests that the field has increasingly focused on procedure-specific and outcome-oriented topics over time.
