[New techniques in thoracic surgery. II].

Abstract

The surgical approach to affections of the chest wall and pleura, still the predominant indications for thoracic surgery, has greatly changed since the advent of thoracoscopic procedures, and is emphasized in this second part of a two-part review, together with other indications for mediastinal tumours. Indicated after lung exeresis or emergency chest surgery, protective chest wall reconstruction with muscular flaps is no longer an exceptional operation. Inversely, thoracic surgery for infectious complications have become less frequent, unusually limited to well established procedures for tuberculosis surgery, treatment of bronchial fistula or mediastinal supperations. The chest cavity is well adapted to new techniques of thoracoscopy and video-assisted thoracic surgery both for diagnosis and treatment. Indications for pleuroscopy have taken on a completely new aspect since 1989. These techniques are used for pericardial fenestration, thoracic sympathectomy for dyshidrosis, vagotomy, splanchnicectomy, chylothorax, spinal affections, empyema and trauma surgery. These new techniques have also had an impact on treatment of spontaneous pneumothorax. For tumour surgery, thoracoscopy has made possible a more adapted strategy currently based on an initial needle biopsy, with limited thoracoscopic exeresis and ultimate treatment depending upon the pathology report. Immediate thoracoscopy without prior biopsy appears excessive. Video-assisted thoracosurgery is also used for most malignant mediastinal tumour which, due to advances in chemotherapy surgery have transformed the prognosis of a large number of mediastinal tumours.
