Medical thoracoscopy combined with argon plasma coagulation as an alternative treatment for intractable pneumothorax: a retrospective study.
Article in Respiratory research, 2025. 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
backgroundA significant proportion of patients with pneumothorax who do not tolerate surgery develop intractable pneumothorax after prolonged failure of conservative treatment. This significantly lengthens the duration of hospitalization and patients' quality of life. As the application of medical thoracoscopy (MT) in the management of pleural diseases is explored, MT combined with argon plasma coagulation (APC) may be an alternative option for the treatment of intractable pneumothorax.
methodsA retrospective analysis was conducted on thirteen patients with intractable pneumothorax whose duration of the air leak exceeded seven days and subsequently treated with MT combined with APC at West China Hospital of Sichuan University. Under MT, we first dissected the pleural adhesions with an electrocautery knife, probed for the rupture located in the pulmonary bullae or pleural and cauterised it with APC. Subsequently, all pulmonary bullae were cauterised and human fibrin sealant was sprayed locally on the cauterised surface. Preoperative, intraoperative, and more than one year of postoperative follow-up information was collected from these patients. We divided the patients into two groups with and without detected ruptures treated under MT to compare the overall efficacy and safety of this treatment.
resultsAll patients had pulmonary comorbidities and the median duration of the current pneumothorax episode before MT treatment was 30 days. Nine patients had a history of recurrent pneumothorax episodes, two of whom had been treated with video-assisted thoracoscopic surgery (VATS). Regarding efficacy, the overall median time of time to air leak cessation was 2.5 days, with 2 days in the group with detected ruptures treated and 5 days in the group without detected ruptures treated, and the overall median time of time to chest tube removal was 6 days, with 4 days in the group with detected ruptures treated and 7 days in the group without detected ruptures treated. Regarding safety, only 2 patients experienced postoperative adverse events of fever and chest pain.
conclusionsFor intractable pneumothorax patients with pleural adhesions that may limit lung re-expansion, who are not candidates for surgery, MT combined with APC can be an alternative treatment option.
