Abstract Introduction Medical thoracoscopy is a minimally invasive and safe procedure mostly performed for unexplained exudative pleural effusions but may be considered for pneumothorax (PNX). Methods This retrospective study included participants affected by PNX who underwent medical thoracoscopy with talc poudrage at a single academic hospital from 2008 to 2021. The primary endpoint was the observation of complete radiographical lung re-expansion and absence of air supply from the chest drain within 7 days of medical thoracoscopy. The secondary endpoint was achieving no recurrence of ipsilateral PNX at 24 months post-discharge. Results A total of 95 patients affected by primary spontaneous PNX (PSP), secondary spontaneous PNX (SSP), iatrogenic, and traumatic PNX were enrolled. An additional procedure was required by 17.89% of patients, and only one patient with SSP required subsequent surgery. Recurrence of PNX occurred on the same side within 24 months after discharge in 9.47% of patients, with a median time to recurrence of 13.5 months. The PSP group was significantly more likely to achieve the primary endpoint. Pleural morphology was significantly associated with reaching the primary endpoint, while receiving a cumulative dose of talc greater than or equal to 4 g during hospitalization was associated with a lower risk of meeting it. Receiving a cumulative dose of talc greater than or equal to 4 g led in all cases to the achievement of the secondary endpoint. Patients with iatrogenic and traumatic PNX had an excellent prognosis in both the short- and long-term evaluation. Conclusion Medical thoracoscopy is an effective procedure for treating PNX in the acute setting in selected cases while preventing long-term relapses. Large prospective clinical studies are needed to support and better define the role of medical thoracoscopy in current clinical practice.
