Various diathermy techniques have been proposed to reduce intraoperative blood loss in surgery. In particular, standard bipolar technology is able to coagulate small vessels, with a diameter ranging from 1 mm to 3 mm, but it has some disadvantages, including sticking, charring, and significant thermal spread [1,2].

The impetus for intrabronchial treatment of emphysema came from the experiences with lung volume reduction surgery (LVRS).

The desire for an objective method to record, quantify, and store lung sound information was the impetus for development of the field of computer-assisted mapping of lung sounds. Techniques are constantly evolving, with many different types of sensors, sensor coupling methods, and digital signal processing techniques in existence.

Introduction

Obstruction of the central airways may develop in 30-40% of all patients with lung cancer and is being increasingly diagnosed in patients with benign disorders such as post intubation tracheal stenosis and connective tissue diseases.

Radio frequency ablation (RFA) of lung tumors is a relatively new procedure allowing local treatment with minimal parenchymal damage. In fact, this technique is able to induce coagulative necrosis in a limited pulmonary area.

Pulmonary nodules and masses are common reasons for referring patients to the pulmonologist, radiologist, and thoracic surgeon for evaluation. The burgeoning use of chest computed tomography for screening, to rule out pulmonary embolism, and for other indications may lead to a significant increase in patients with newly discovered lesions.

Emphysema affects an estimated 60 million people worldwide. It is a disease associated with significant morbidity in the form of dyspnea and exercise limitation and mortality. The pathology behind this is the destruction of pulmonary parenchyma, both alveolar walls and interstitial tissue.
