A nationwide survey of uniportal thoracoscopic anatomical pulmonary resections in Japan.

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
Background: Uniportal thoracoscopic surgery has gained popularity as a minimally invasive approach for anatomical lung resection. While outcomes from high-volume centers have been reported, evidence describing nationwide real-world practice across institutions with varying experience is scarce. This study aimed to evaluate the current status and perioperative outcomes of uniportal thoracoscopic anatomical pulmonary resections in Japan. Methods: We conducted a multicenter retrospective study under the Japanese Uniportal Video-assisted Thoracoscopic Surgery Interest Group. Patients with primary lung cancer who underwent uniportal thoracoscopic lobectomy or segmentectomy in Japan between April 2018 and March 2023 were included. Clinical information was collected from participating institutions, and patient characteristics, operative variables, and perioperative outcomes were evaluated. The primary outcome was the incidence of procedure-related complications, with secondary outcomes including operative time and other perioperative parameters. Results: A total of 3,546 patients were analyzed, comprising 2,780 lobectomies and 766 segmentectomies. The proportion of segmentectomies gradually increased during the study period. In the lobectomy group, the median operative time was 170 min, with prolonged air leak in 7.6% and significant vessel injury in 3.4%. In the segmentectomy group, the median operative time was 154 min, with prolonged air leak in 4.6% and significant vessel injury in 3.5%. Thirty-day mortality was 0.3% in both groups, and conversion to multiport or thoracotomy occurred in 1.8-3.6% of cases. Conclusions: This nationwide analysis indicates that uniportal thoracoscopic anatomical pulmonary resection is performed safely in Japan, with perioperative outcomes comparable to those reported internationally. Although operative times were slightly longer than those in single-institution series, complication rates remained low, indicating that uniportal thoracoscopic anatomical pulmonary resection is being conducted with acceptable perioperative outcomes in real-world practice.
