Preoperative 3D-CT evaluation of the bronchial arteries in transmediastinal radical esophagectomy for esophageal cancer.
Article in Esophagus : official journal of the Japan Esophageal Society, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundIn transmediastinal esophagectomy (TME) with equivalent lymphadenectomy to transthoracic procedure, an understanding of surgical anatomy in the deep mediastinum near the aortic arch or tracheal bifurcation is essential for the safe procedure. The present study aimed to evaluate the bronchial arteries (BAs) with preoperative 3D-CT in TME.
methodsSeventy-nine patients with thoracic esophageal cancer undergoing TME were examined by preoperative 3D-CT to evaluate BA variations in the number, branching pattern, and mediastinal course. For the right BAs (RBAs) crossing the esophagus, the mediastinal courses in transcervical view were classified in relation to the esophagus and tracheobronchi and compared with surgical findings.
resultsA total of 107 RBAs (1.35/person) were confirmed on preoperative 3D-CT. Of these, 61 (57.0%) crossed the esophagus dorsally (type Ed), and the remaining 46 (43.0%) crossed the esophagus ventrally (type Ev). During the left transcervical procedure, all type Ed RBAs were identified and mostly preserved (57/61, 93.4%) whereas most type Ev RBAs were identified (39/46, 84.8%), but more than half were sacrificed (26/46, 56.5%) for lymphadenectomy. The blood loss during the transcervical procedure was 17.0 ± 55.8 ml. The total number of dissected mediastinal lymph nodes was 23.7 ± 9.3. There were no significant complications related to extensive lymphadenectomy.
conclusionsPreoperative 3D-CT evaluation is useful to understand the mediastinal courses of BAs specific to the transcervical approach, which may allow BAs to be handled more carefully according to the type during surgery, contributing to a safer procedure in the deep mediastinum.
