Background: The current discourse within the thoracic surgical and pulmonological communities pertains to a contentious debate over the optimal selection criteria for thoracostomy tube diameters utilized in the management of pleural effusions. A comprehensive examination of the variables that inform the clinical decision-making paradigm for the determination of appropriate chest tube calibers is imperative to enhance patient management and elevate the prognostic results. Objectives: The objective of this inquiry is to elucidate the determinants that influence thoracic surgeons and pulmonologists in their selection of chest tube size for the management of pleural effusions. Methods: This cross-sectional study was based on an electronic questionnaire that was sent to the targeted populations through e-mail or a professional WhatsApp. The survey assessed the considerations of chest tube size selection as well as the respective advantages, disadvantages, and potential complications related to each size. Results: The conducted study encompassed participants, with a nearly even distribution between thoracic surgeons (49.1%) and pulmonologists (50.9%). Most of these practitioners are within tertiary-level medical institutions (82.1%). A preference for small-bore chest tubes (SBCT), defined as < 14 French (Fr), was indicated by 54.8% of participants. The drawbacks associated with SBCT, such as kinking (60%) and blockage (70%), influenced the decision-making process negatively, while pain was a significant factor in the selection against LBCT (64%). Ultrasound guidance was a positive influence for the selection of SBCT (55%). Complications associated with LBCT included visceral and vascular injuries (55.7%), wound infection (45.3%), re-expansion pulmonary edema (43.3%), and subcutaneous emphysema (57.5%). In contrast, malposition was a complication more commonly associated with SBCT (49.1%). Conclusion: The decision regarding chest tube size was influenced by several critical factors which included the nature of pleural effusion, the volume of pleural fluid, and potential complications specific to the size of the chest tube used.

Chylothorax is a rare condition where the extravasated chyle accumulates into the pleural space. It is most commonly associated with malignancies, infective or inflammatory disorders and iatrogenic causes. Extremely rarely, it could occur spontaneously. We present the case of a healthy 40-year-old woman who presented with acute right shoulder and neck pain associated with shortness of breath and loss of consciousness. This was preceded by a yoga class two weeks prior. Chest imaging showed right pleural effusion, and tapping revealed a milky fluid which was confirmed to be chylothorax. Conservative management failed and the patient was successfully treated with video-assisted thoracoscopic drainage, thoracic duct ligation and mechanical pleurodesis. Chylothorax association with yoga is not reported in the literature. [ABSTRACT FROM AUTHOR]
