Background: In the absence of significant pleural effusion, conventional medical thoracoscopy (MT) is often not feasible due to the risk of lung injury. Dry MT mitigates these risks by inducing artificial pneumothorax through needle insufflation or blunt dissection. Although the Veress needle is commonly used by surgeons to create pneumoperitoneum before laparoscopic surgeries, its application in dry MT has not been widely reported in recent times. Methods: We report on a series of 31 patients who underwent dry MT with artificial pneumothorax induction using Veress needle under thoracic ultrasonography (TUS) guidance. A procedure was considered technically successful if it met all the following criteria: successful pneumothorax induction, allowing smooth insertion of the semi-rigid thoracoscope; absence of immediate significant procedural-related complications; and no delayed complications such as persistent air leaks, defined as leakage lasting more than 5 days necessitating extended chest tube placement. Results: Complete pneumothorax induction was achieved in 25 cases, resulting in an 80.6% technical success rate; however, biopsies were successfully performed in all cases. The most frequent histopathological diagnoses were malignancy (n=9, 29.0%), followed by inflammatory pleuritis (n=8, 25.8%) and tuberculosis (n=8, 25.8%). No procedural complications were reported. Conclusion These results indicate that TUS-guided dry MT utilizing a Veress needle is technically feasible and secure when performed by experienced MT practitioners in TUS.
