Surgical simulation of minimally invasive bronchial sleeve resection and reconstruction using interactive 3-dimensional airway models.
Article in Langenbeck's archives of 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
purposeBronchial sleeve resection is a lung-sparing procedure that avoids pneumonectomy and reduces postoperative mortality, but it remains technically demanding. The rise of minimally invasive approaches such as video-assisted thoracic surgery (VATS) and robotic-assisted thoracic surgery (RATS) adds further complexity, increasing the need for realistic and high-fidelity training. The purpose of this study is to develop high fidelity dry lab for minimally invasive bronchial sleeve resection and reconstruction.
methodsA modular chest wall training device was created to support various minimally invasive approaches. The module includes 25 configurable 30 mm ports with detachable 8 mm rubber plugs, allowing simulation of multiportal and uniportal VATS, as well as RATS. A 3-dimensional precise bronchial model derived from computed tomography data was used to simulate right upper lobe sleeve resection. The training model was evaluated with a 5-point Likert scale (surgical exposure, manipulation, and usefulness as training) after four board-certified thoracic surgeons performed simulations with both approaches.
resultsThe training was successfully conducted using both thoracoscopic and robotic approaches and could be repeated with no issues in port interference or stability. The evaluation by the four thoracic surgeons was generally acceptable (VATS: median score [range] on a 5-point Likert scale: surgical exposure 3.5 [2-5], manipulation 2.5 [2-5], usefulness as training 4.0 [4-5]. Robotic-assisted surgery: surgical exposure 4.5 [4-5], manipulation 4.0 [4-5], usefulness as training 5.0 [4-5]).
conclusionThis training system helps thoracic surgeons prepare for the growing demand for this type of procedure and ultimately improve surgical outcomes.
