Predictive factors of difficulty of thoracoscopic esophagectomy in the left decubitus position.
Article in Esophagus : official journal of the Japan Esophageal Society, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundWe have sometimes experienced technical difficulty performing thoracoscopic esophagectomy because of the position of the descending aorta or width of the mediastinal space. In this study, we retrospectively investigated predictive preoperative factors that influence the procedure of thoracoscopic esophagectomy with a focus on the position of the descending aorta and width of the mediastinal space.
methodsNinety-five patients who underwent thoracoscopic esophagectomy for esophageal cancer by two specialists were included in this study. Thirty patients in whom both the operation time and blood loss in the thoracic region exceeded the median were categorized to the difficult group. The remaining 65 patients were categorized into the common group. During the evaluation of the position of the descending aorta, we measured the aorta-vertebra angle at the level of the left inferior pulmonary vein. During the evaluation of the width of the mediastinal space, we measured the sternum-vertebra distance at the level of the tracheal bifurcation.
resultsA forward stepwise logistic regression analysis revealed the following independent predictive factors of the technical difficulty of thoracoscopic esophagectomy: aorta-vertebra angle (≥ 30°), sternum-vertebra distance (< 100 mm), and clinical T stage (T3).
conclusionsThe position of the descending aorta, width of the mediastinal space, and clinical T stage are predictive factors of the technical difficulty of thoracoscopic esophagectomy. These factors might become supporting indices for the indication for thoracoscopic esophagectomy among trainees or the surgeons who introduce this procedure.
