Flexible bronchoscopy can play an important role in the evaluation of an airway lumen during therapeutic bronchoscopic procedures. Despite its potential usefulness, however, evaluation with a standard-sized bronchoscope, which cannot pass completely through a severely stenosed airway, is often unsatisfactory. ⋯ The thin bronchoscope can be a useful tool for evaluating a severely stenosed airway during the stenting procedure.

We report a 12-year-old boy who underwent stent implantation into the left main bronchus at the age of 9.5 years for palliation of severe bronchial stenosis. He had developed complete obstruction of the stent by granulation tissue resulting in respiratory deterioration and the requirement of mechanical ventilation. The stent obstruction was treated at the age of 11.5 years by cryorecanalization. ⋯ Seven months after the initial procedure there was a complete patency of the stent. According to our experience, cryorecanalization is a safe and effective alternative for the treatment of stent obstruction by granulation tissue. Due to the introduction of a miniaturized probe, this method is well applicable in children since it can be performed via the working channel of a flexible pediatric bronchoscope.

Increased risk of spontaneous pneumothorax has been described in patients with Marfan syndrome and has been attributed, in part, to the presence of apical blebs and bullae. ⋯ The frequency of blebs is relatively low in patients with Marfan syndrome but the risk of pneumothorax is significantly higher in those with radiologically detectable blebs or bullae. Chest CT scanning to identify blebs and bullae may allow risk stratification for pneumothorax in patients with Marfan syndrome.

So far, the association of lung cancer with chronic hypersensitivity pneumonitis (CHP) has not been studied. ⋯ Since the prevalence of lung cancer in CHP seems to be high (10.6%) as seen in idiopathic pulmonary fibrosis, physicians should be aware of the possible complication of lung cancer in CHP.

Parapneumonic effusions or empyemas are frequently seen in patients with lower respiratory tract infections. The condition is associated with significant morbidity and mortality. Since Gram stains and bacterial cultures are usually negative, treatment focuses on empiric antibiotic treatment and chest tube drainage. ⋯ Furthermore, it can be performed in analgo-sedation in a bronchoscopy suite. Video-assisted thoracic surgery carries the advantage of providing optimal visibility of the pleural cavity, thus allowing better debridement. Thoracotomy is the treatment of choice when thoracoscopic cleaning is not satisfactory.
