Pneumothorax after percutaneous transthoracic lung biopsy. Non-invasive management in order to avoid unnecessary hospitalizations.

Background: Image-guided percutaneous transthoracic lung biopsy has become a widely used and less invasive diagnostic method. Pneumothorax is the most frequent complication after lung biopsy. The aim of the present study is to describe the experience with expectant management of asymptomatic small post-biopsy pneumothorax in order to reduce unnecessary hospital admissions.

Accuracy of positron emission tomography and computed tomography (PET/CT) in detecting nodal metastasis according to histology of non-small cell lung cancer.

Positron emission tomography and computed tomography (PET-CT) is the non-invasive gold standard method for determining the oncological stage of patient with diagnosis of lung cancer. A correct preoperative staging is significant because only patients who do not have a history of regional or distant disease are those who will benefit from a surgical treatment. However, due to the different values of the PET-CT in terms of sensitivity and specificity to evaluate the mediastinal lymph node involvement, it is often necessary to perform a surgical mediastinal sampling through a cervical video mediastinoscopy (VM).
