Articulation analysis of robotic staplers in rectal surgery.
Article in Surgery today, 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
purposesRobotic staplers offer several advantages in rectal surgery owing to their wide range of articulation and ergonomic manipulation. These benefits are evident during mobilization of the mesentery from the surrounding tissue and dissection of the rectum. However, no study has quantitatively evaluated the robotic stapler articulation in rectal surgery.
methodsWe retrospectively enrolled 110 patients who underwent robotic anterior resection and double-stapling anastomosis. Stapling-related variables, including the type of cartridge, number of firings, time for initial stapling, and pitch/yaw of the stapling arm joint, were collated, and their association with patient background variables was analyzed.
resultsThe pitch ranged from - 56° to - 0.2° (median, - 36.3°), and the yaw ranged from - 57.9° to 54.2° (median, - 7.5°). A multivariate analysis showed that a more negative pitch value was independently associated with surgery for cT3/4 cancers (p = 0.042). Moreover, the pitch decreased as the distance from the anus to the staple line increased (p < 0.001). Female sex was the only factor independently associated with yaw (p = 0.029). Univariate analyses revealed that age ≥ 70 years, preoperative treatment, short cartridge selection, and multiple firings were correlated with a high anastomotic leakage rate.
conclusionsThis study clearly demonstrates how surgeons utilize the unique functions of robotic staplers during rectal transection.
