BACKGROUND: Whether body mass index (BMI) is a significant risk factor for recurrence of primary spontaneous pneumothorax (PSP) remains controversial. The purpose of this study was to examine whether BMI and other factors are linked to risk of PSP recurrence. METHODS: A consecutive cohort of 273 patients was retrospectively evaluated. Patients were divided into those who experienced recurrence (n = 81) and those who did not (n = 192), as well as into those who had low BMI (n = 75) and those who had normal or elevated BMI (n = 198)...

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has been widely used for spontaneous pneumothorax (SP). In recent years, thoracic surgeons have attempted single incision or single port surgery with the development of surgical technology and skills. Theoretically, single port surgery is expected to provide benefits such as less pain and early recovery. The purpose of this study was to determine the benefits of single port surgery in SP. METHODS: The 107 patients with SP who underwent surgery, between July 2013 and May 2015, were reviewed retrospectively...

A-21-year old man presented with dyspnea and a chest radiograph showed a right pneumothorax. Chest computed tomography revealed a collapsed lung and floating membrane, which was the lowermost part as a tear-shaped shadow. After the chest tube was inserted and surgical management was performed using a video-assisted thoracoscopic approach. At surgery, the visceral and parietal layers of pleura forming the mesoazygos were not fused, and azygos vein had a partial mobility. There was no adhesion between an upper lobe and visceral pleura...

The process of elastin and collagen fiber destruction was presented based on the example of the changes taking place in the course of chronic obstructive pulmonary disease and primary spontaneous pneumothorax. In 1963, when analyzing patients with α1 antitrypsin deficiency, Dr Laurell and Dr Eriksson hypothesized that elastolysis plays a role in the pathogenesis of emphysema, which marked the beginning of studies aimed at analyzing this process. The present work concerns new scientific reports regarding the hypothesis...

RATIONALE: Patients without a known history of lung disease presenting with a spontaneous pneumothorax are generally diagnosed as primary spontaneous pneumothorax. However, occult diffuse cystic lung diseases such as Birt-Hogg-Dubé syndrome (BHD), lymphangioleiomyomatosis (LAM), and pulmonary Langerhans cell histiocytosis (PLCH) can also first present with a spontaneous pneumothorax, and their early identification by high-resolution computed tomographic (HRCT) imaging of chest has implications for subsequent management...

A novel FLCN c.1489_1490delTG (p.Val497Glyfs*22) mutation at the genomic DNA and mRNA levels was identified in a 43-year-old woman with complaining of recurrent primary spontaneous pneumothorax. The aberrant FLCN mRNA escaped the nonsense-mediated decay system (NMD) because of a premature termination code located in an NMD-incompetent region. To the best of our knowledge, this is the first case report of an FLCN mutation escaping the NMD.

Primary spontaneous pneumothorax (PSP) occurs most frequently in young, tall, lean, male smokers without any known underlying lung disease. It is an important diagnosis to make promptly in order to prevent progression to obstructive shock. We present a case report of a young, male, former-smoker and polysubstance abuser with no prior lung history that developed acute dyspnea at rest and was found to have a large right pneumothorax on chest x-ray. A pig-tail catheter was utilized, but his course was complicated by a recurrent tension pneumothorax...

INTRODUCTION: Current management of primary spontaneous pneumothorax (PSP) is variable, with little evidence from randomised controlled trials to guide treatment. Guidelines emphasise intervention in many patients, which involves chest drain insertion, hospital admission and occasionally surgery. However, there is evidence that conservative management may be effective and safe, and it may also reduce the risk of recurrence. Significant questions remain regarding the optimal initial approach to the management of PSP...

To manage primary spontaneous pneumothorax, we use an alternative technique for bleb resection and we induce pleurodesis with an ultrasonic-driven scalpel. This technique was successfully performed in nine consecutive patients with primary spontaneous pneumothorax with small (<20 mm) and limited number of blebs (<2) and without significant underlying lung disease. After identification of air leakage, the jaws of the instrument were clamped onto the bleb and included a margin of normal lung. Power level 3 energy was applied to resect the bleb and to seal the parenchyma...

We reported the feasibility of single-incision thoracoscopic surgery bullectomy using a chest wall pulley for lung excision (PulLE) in patients with primary spontaneous pneumothorax (PSP). PulLE has many merits including comfort of manipulation, cosmetic advantages, etc., compared to other procedures. However, our method was utilized for relatively straightforward cases. The PulLE was contraindicated for PSPs with multiple or comprehensive bullae. Therefore, we developed the modified PulLE (mPulLE) to treat such cases in February 2015...

BACKGROUND: Single-incision thoracoscopic surgery (SITS) requires extensive time and practice to achieve satisfactory technical skills. The aim of this study was to evaluate the learning curves of SITS for primary spontaneous pneumothorax (PSP). METHODS: This study included a total of 274 consecutive patients who underwent PSP surgery by a single operator between May 2011 and February 2014. During this period, SITS was applied as a routine approach. Learning curves were made by the cumulative sum (CUSUM) method using the number of cases and four surgical technique-related factors, including operation time, postoperative complication, non-SITS rate, and ipsilateral PSP recurrence...

BACKGROUND: Conventional 3-port video-assisted thoracoscopic surgery is the classic approach for the diagnosis and treatment of primary spontaneous pneumothorax. Transareolar pulmonary bullectomy rarely has been attempted. This study aimed to evaluate the feasibility and safety of this novel minimally invasive technique in managing primary spontaneous pneumothorax. METHODS: From January 2013 to December 2014, a total of 112 male patients with primary spontaneous pneumothorax underwent transareolar pulmonary bullectomy by use of a 5-mm thoracoscope...

BACKGROUND: High-flow nasal cannula (HFNC) therapy is increasingly used in pediatric ICUs as an intermediate level of support between conventional oxygen delivery and noninvasive ventilation (NIV). The safety of HFNC has seldom been studied, and some cases of barotrauma have been reported. This retrospective study aims to describe HFNC use in a tertiary care pediatric ICU, with a focus on the complications associated with this therapy. METHODS: Between January 2013 and January 2014, all children <18 y old treated with HFNC in the pediatric ICU were included...

Introduction. Primary spontaneous pneumothorax (PSP) is a disorder commonly encountered in healthy young individuals. There is no differentiation between PSP and secondary pneumothorax (SP) in the current version of the International Classification of Diseases (ICD-10). This complicates the conduct of epidemiological studies on the subject. Objective. To validate the accuracy of an algorithm that identifies cases of PSP from administrative databases. Methods. The charts of 150 patients who consulted the emergency room (ER) with a recorded main diagnosis of pneumothorax were reviewed to define the type of pneumothorax that occurred...

The incidence of nontuberculous mycobacterial pulmonary disease (NTMPD) is increasing worldwide. Secondary spontaneous pneumothorax occurs as a complication of underlying lung disease and is associated with higher morbidity, mortality, and recurrence than primary spontaneous pneumothorax. We here investigated the clinical features and long-term outcomes of pneumothorax associated with NTMPD.We conducted a retrospective study on consecutive adult patients with pneumothorax associated with NTMPD at Fukujuji Hospital and Keio University Hospital from January 1992 to December 2013...

Single port thoracic surgery, reduced port surgery and needlescopic surgery attract attention as one of the minimally invasive surgery in thoracic surgery recently. Single port thoracic surgery was advocated by Rocco in 2004, it was reported usefulness of single port thoracic surgery for primary spontaneous pneumothorax. The surgical procedure as single (or reduced) port thoracic surgery is roughly divided into the following. One is operated with instruments inserted from the single extended incision, and the other is operated with instruments punctured without extending incision...
