Robotic-Assisted Bronchoscopy for Volume Reduction of Giant Emphysematous Bulla: A Case Report.

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
We report the first successful case of volume reduction of a giant emphysematous bulla (GEB) using the latest shape-sensing robotic-assisted bronchoscopy (ssRAB). The patient was a 70-year-old male with chronic obstructive pulmonary disease (COPD) who developed GEB. He had previously undergone endobronchial valve (EBV) removal due to pneumonia caused by long-term implantation of EBVs for bulla volume reduction after a left emphysematous bulla rupture and subsequent pneumothorax. The patient visited our hospital for gradually worsening shortness of breath over two months. Chest radiography and computed tomography (CT) showed a GEB compressing 60% of the right lung volume, with the largest part filling the entire cross-section of the right lower lung. Under general anesthesia and with the assistance of ssRAB, we precisely punctured the bulla, safely aspirated the gas within the bulla, and injected medical adhesive to close the bulla. Postoperatively, the patient's shortness of breath improved significantly, and a CT follow-up six months later showed that the bulla had reduced to about half of its original size. Our experience indicates the feasibility and potential benefits of the novel ssRAB for volume reduction of GEB. The long-term efficacy and safety of using ssRAB to reduce GEB need to be evaluated by larger-scale studies.
