AB Extended thoracoscopy (ET) allows several large biopsies to be taken in patients with thick adhesions of the pleura when normal thoracoscopy is impossible. Twenty patients with undiagnosed pleural effusion or thickening and two with associated pulmonary tumour close to the chest wall underwent ET because closed adhesions prevented the induction of an artificial pneumothorax. Under local anaesthesia and neuroleptanalgesia, at the site of suspected lesions on computed tomographic (CT) scan, a cutaneous incision of 3-4 cm is made on the appropriate intercostal space. After dissection with blunt scissors, the operator introduces his finger to create a space in the pleural cavity. The thoracoscope is inserted to inspect the pleura and to take several biopsies for histopathological examination. A chest tube is inserted for a few minutes after checking airtightness and haemostasis. The procedure is well-tolerated. In three cases no pleural biopsy could be taken; in three patients a false negative diagnosis was observed. A correct diagnosis was obtained in 16 out of 19 patients (84%). If performed by a pulmonologist experienced with thoracoscopy ET is a rapid, safe and efficient method to obtain biopsies in cases where normal thoracoscopy after induction of a pneumothorax is not possible. It considerably reduces the need for open thoracotomy.
