Evaluation of the Efficacy of a Digital Chest Drainage System in Traumatic Pneumothorax.

INTRODUCTION: Pneumothorax is the major complication in patients with chest trauma. Thoracic injury is a major cause of trauma-related deaths, with up to half of these patients developing pneumothorax. The initial primary management of pneumothorax is intercostal chest drainage (ICD). Chest drainage systems are used to resolve pleural air leakage (PAL), lymphatic or exudative effusion, blood accumulation after chest surgery or trauma, and other disease conditions such as pneumothorax. This study evaluates the efficacy of a digital chest drainage system (Thopaz+, Medela AG, Baar, Switzerland) in patients with pneumothorax following chest trauma and analyzes the satisfaction score by patients. METHOD: A hospital-based cross-sectional study was conducted in a tertiary care centre at the Department of Cardiovascular and Thoracic Surgery (CTVS). All patients with a diagnosis of traumatic pneumothorax/hemopneumothorax from January 2021 to June 2022, aged more than 15 years, were enrolled for the study. A total of 102 patients required chest drainage systems and were selected for the study. We analysed demographic data, clinical profiles, and routine investigations with chest X-rays and computed tomography (CT) scans. All patients were connected with digital drainage devices and monitored for air leaks and other complications. Patient satisfaction was evaluated by a purposefully developed survey questionnaire. RESULTS: Most of our study subjects were male (84.3%) and the mean age was 42.38±15.75 years. The total duration of chest tube, post-operative air leak and duration of hospital stay were noted. The mean chest tube duration was 4.39±1.18 days. Twelve patients were found to have air leaks with digital drainage devices. The mean duration of hospital stay was 5.75±1.49 days. All subjects were provided with a survey questionnaire to assess their response to digital drainage devices. We found that patients were comfortable and had positive responses for the Thopaz+ device. CONCLUSION: We found that Thopaz+ digital drainage system is useful in reducing chest tube duration and hospital stay. It also helps in the early resolution of air leaks and minimises complications. Most of our patients showed a positive attitude. With regard to Thopaz+ digital device, our study concludes that Thopaz+ should be considered for patients who need chest tube drain for pneumothorax.

Pulmonary sclerosing pneumocytoma masquerading adenocarcinoma with co-existing BRAF V600E and PTEN mutation.

We report a case of a massive primary sclerosing pneumocytoma (PSP) involving the right lower lobe adhering esophagus with small synchronous PSP on the superior segment of the left lower lobe with concurrent mutation for B-RAF proto-oncogene, serine/threonine kinase (BRAF V600E), and phosphatase and tensin homolog (PTEN) gene in a young female. She underwent right lower lobectomy and mediastinal lymph node dissection under single lung ventilation with tumor-free margins on diagnosis-based findings of preoperative computed tomography-guided biopsy and positron emission tomography. Histopathology was suggestive of PSP-papillary variant with concurrent mutation of BRAF V600E and PTEN genes. Post-operative follow-up at four weeks was uneventful. She has to undergo wedge resection for the contralateral disease after six weeks following recovery from the first surgery.

Chondrosarcoma of the Rib: Atypical Presentation and Management.

Chondrosarcoma is an uncommon malignant tumor of the rib and can have an atypical presentation based on age, gender, and clinical manifestation with differential diagnosis of intrathoracic mass. Management is surgical as the tumor is resistant to chemoradiation. Access to chest wall reconstruction is limited in many low-income countries and forms a barrier to patient compliance. We report an atypical presentation and describe a simple, easy, and cost-effective chest wall reconstruction method for chondrosarcoma of the rib in any resource-constrained setting.

Le chondrosarcome est une tumeur maligne peu commune de la côte et peut avoir une présentation atypique en fonction de l'âge, du sexe et de la manifestation clinique avec un diagnostic différentiel de masse intrathoracique. La prise en charge est chirurgicale car la tumeur est résistante à la chimioradiation. L'accès à la reconstruction de la paroi thoracique est limité dans de nombreux pays à faible revenu et constitue un obstacle à l'adhésion des patients. Nous rapportons une présentation atypique et décrivons une méthode de reconstruction de la paroi thoracique simple, facile et rentable pour le chondrosarcome de la côte dans un contexte de ressources limitées.
