Background - Assessment of the percentage of lung collapse is crucial in the therapeutic decision-making of pneumothorax. - The methods normally used to this purpose are radiological. Computerized tomography scan (CT) is highly accurate because it allows the exact evaluation of the volume of the air layer. However, in clinical practice assessment of the volume of pneumothorax mainly relies on the measurement of the inter-pleural distance at conventional chest radiography (CXR). This latter method is inaccurate. - Lung ultrasound is a new method highly accurate in the first diagnosis of pneumothorax, with a sensitivity superior to CXR and similar to CT in case of traumatic pneumothorax. - The scientific community is actually debating about the usefulness of lung ultrasound in the quantification of pneumothorax []. Lung ultrasound can assess the superficial extension of the pneumothorax, but cannot evaluate its volume. Aim - Main purpose of the study is to compare measurement of the superficial extension of pneumothorax on the chest wall obtained by lung ultrasound, to the evaluation of the air volume performed by CT in patients with pneumothorax. - The main hypothesis of the study is that the cut-off between small (<11% of lung collapse) and large (>11% of lung collapse) pneumothorax can be identified by a lung ultrasound evaluation of the superficial extension of pneumothorax. - Second purpose of the study is to compare the accuracies of lung ultrasound and CXR in predicting the volume of pneumothorax assessed by CT. - Secondary hypothesis is that lung ultrasound demonstrates greater accuracy in the prediction of volume of pneumothorax and percentage of lung collapse. Methods - Patients with a diagnosis of pneumothorax confirmed at CT are prospectively enrolled and submitted to lung ultrasound within 20 min from the CT study. - Different locations of the sonographic "lung point" on the chest wall (i.e. the point on the chest wall where the sonographic pattern of the normally aerated lung alternates with the pathologic sonographic pattern of pneumothorax) are compared with different volumes of pneumothorax measured by CT.
The purpose of this study is to investigate whether if KatGuide (a new developed medical device) improves the placing of a large bore chest tube in the pleural cavity compared to the conventional method.
A retrospective study to demonstrate the optimal depth of right side bronchial blocker for complete right lung separation. Data were collected from all patients who completed right side VATS with right side BB from Jan 2010 through Nov 2010.
The investigators conducted a prospective randomized study to compare axillary minithoracotomy versus a modified two-port thoracoscopic technique for surgical pleurodesis in patients with recurrent spontaneous pneumothorax operated in a single institution. The main objective of the study was to investigate possible differences regarding short- and long-term clinical outcome between the two different techniques.
The purpose of this study is to examine the efficacy of prophylactic antibiotics in patients with chest tubes for management of thoracic injuries in the reduction of the incidence of empyema as compared to placebo.
Management of primary spontaneous pneumothorax (PSP) remains unclear. Primary therapeutic goals for PSP include removal of air from the pleural space an prevention of recurrences. The absence of generally accepted and methodologically sound recommendations may account for the extensive variation in practice for air evacuation techniques. Air evacuation may be achieved by simple aspiration (exsufflation) or conventional chest tube drainage. Chest tube thoracotomy remains the most popular technique.Aspiration is a more simple technique, that allows possibility of ambulatory management. The purpose of the present study is to compare simple aspiration performed with a specific thoracentesis device, versus conventional chest tube drainage. Comparison will be performed on immediate efficacity of resolution of the pneumothorax.The hypothesis is that simple aspiration performed with a specific device is not inferior to chest tube drainage for management of a first episode of large size primary spontaneous pneumothorax. A second goal is to measure the efficacy at one week, and the recidive at one year. The trial is randomized, controlled and will include 200 patients for each group. The patients will be enrolled in 29 hospitals in France. Emergency department, thoracic surgery and pulmonary departments of each hospital were primarily contacted for agreement to participate to the study.
Treatment of recurrent primary spontaneous pneumothorax remains controversial and many therapeutic options exist. The aim of this study is to compare pleural symphysis by talc poudrage during medical thoracoscopy and surgical management combining pleural abrasion and blebs or bullae resection for treatment of recurrent primary spontaneous pneumothorax.
For the definite treatment of primary spontaneous pneumothorax(PSP), thoracoscopic bleb obliteration with pleural adhesive procedure is generally accepted as a standard. But additional pleurodesis is potentially useless procedure on the parietal pleura for treating visceral pleural disese. Furthermore, pleural symphysis could deteriorates normal pleural physiology and cause chronic pain. According to our previous study, stapling resection of the bulla without pleurodesis gave comparable result in recurrence comparing with articles with additional pleurodesis. The purpose of this study is to evaluate surgical outcome of thoracoscopic surgery with or without pleural abrasion and to know whether adhesive procedure is essential in the management of PSP.
The purpose of this study is to determine whether chest tubes can be safely removed without considering how much fluid is draining through the tube.
