Clinical factors associated with rescue bronchoscopic sputum suction after minimally invasive esophagectomy: A single-center retrospective study.
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
purposePostoperative sputum retention after minimally invasive esophagectomy may require bronchoscopic sputum suction when conservative airway clearance is insufficient. However, the clinical features associated with this intervention remain unclear.
methodsWe retrospectively reviewed the data of 145 patients who underwent minimally invasive esophagectomy for thoracic esophageal cancer. Patients were divided into those who required postoperative bronchoscopic sputum suction and those who did not. Clinicopathological factors, surgical outcomes, Brinkman Index, pulmonary function, and postoperative complications were compared.
resultsPostoperative bronchoscopic sputum suction was required in 21 patients. All bronchoscopic procedures were performed after transfer from the intensive care unit to the general ward. The bronchoscopic group had a significantly higher Brinkman Index than the no-bronchoscopic group, whereas standard spirometric parameters, including forced vital capacity, forced expiratory volume in 1 s, and the forced expiratory volume in 1 s percentage, did not differ between the groups. Patients requiring bronchoscopy had higher rates of postoperative pneumonia and anastomotic leakage and a significantly longer postoperative hospital stay.
conclusionIn patients undergoing minimally invasive esophagectomy, greater cumulative smoking exposure was associated with rescue bronchoscopic sputum suction despite comparable preoperative spirometry. Therefore, a high Brinkman index may indicate the need for closer postoperative respiratory surveillance and timely airway clearance.
