CME right colectomy with D3 lymphadenectomy for colon cancer through a bottom-to-up approach using CMR versius robotic system: an IDEAL stage 1 report.
Article in Updates in surgery, 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
New robotic platforms are entering clinical practice, necessitating standardisation of surgical technique. This study presents the first case series (IDEAL Stage 1) of bottom-to-up complete mesocolic excision (CME) right colectomy with D3 lymphadenectomy using the CMR Versius Robotic System. The procedures were conducted as part of the COMPAR trial at Azienda Ospedaliera Universitaria Integrata of Verona. Port set-up and BSU positioning were iteratively refined across cases in accordance with IDEAL Stage 1 methodology. Six patients were enrolled. Technical refinements were introduced after case 3 to optimise traction and exposure. Median operative time was 296 min (range 233-410). No intraoperative complications occurred; one patient required conversion to laparoscopy. All resections were R0 with a median lymph node yield of 27 (range 20-34). This IDEAL Stage 1 report demonstrates the technical feasibility of the bottom-to-up CME approach using the CMR Versius system. Iterative refinements were essential to optimise the procedure; further prospective studies (IDEAL Stages 2-4) are needed to evaluate reproducibility and clinical value.
