Robotic versus laparoscopic surgery for right-sided colon cancer: is it better for central lymph nodes harvesting in right colectomy with complete mesocolic excision?
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe purpose of this study is to compare the total number of central lymph nodes harvested among right-sided colon cancer (RCC) patients who underwent complete mesocolic excision (CME)-right colectomy with robotic and laparoscopic techniques.
methodsA consecutive series of patients who underwent elective right colectomy for right colon cancer utilizing either laparoscopy or robotic techniques between January 2018 and December 2025. The number and distribution of apical lymph nodes identified in the final pathology reports were assessed and compared between the two groups.
resultsRobotic CME was associated with a significantly higher total lymph nodes yield (33.5 vs. 29.1; p = 0.013) and superior apical nodes harvest (11.7 vs. 7.8; p < 0.001) compared to laparoscopic CME. Specifically, the robotic approach yielded more nodes at the right superior colic vein (2.2 vs. 1.0; p = 0.006) and the right branch of the middle colic artery (2.5 vs. 1.8; p = 0.018). While RRC had longer operative times (256.5 vs. 229.9 min; p < 0.001), it was associated with a significantly shorter length of stay (5.0 vs. 6.5 days; p < 0.001) and faster recovery of bowel function (p < 0.001).
conclusionRobotic CME for RCC allows for more extensive central lymphadenectomy than laparoscopy, particularly at critical vascular origins. Combined with enhanced functional recovery and reduced morbidity, these findings support the adoption of robotic technology for CME resections.
