Three-dimensional simulation-based wedge resection for non-palpable small lung lesions.

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
Three-dimensional simulation is widely used for anatomical segmentectomy, but its application to wedge resection is less standardized. We describe a 3D simulation-based wedge resection technique for selected non-palpable small lung lesions, particularly those in which intraoperative localization is difficult because of their depth or small size. Preoperative simulation identifies preserved intrapulmonary bronchovascular structures and defines a landmark-constrained transection surface with an adequate margin. During thoracoscopic surgery, these structures are exposed as landmarks, not divided as in anatomical segmentectomy, and staplers are applied along the planned surface. The technique is intended for lesions for which wedge resection is oncologically acceptable but empirical stapled wedge resection may provide unreliable localization or margin control. In selected patients, 3D simulation-based wedge resection may be a useful adjunct for planning localization- and margin-oriented parenchyma-sparing resection.
