[Significance of explorative thoracotomy in the diagnosis and symptomatic treatment of bronchogenic carcinoma].

Diagnostic imaging and mediastinoscopy have reduced but not eliminated the exploratory thoracotomy in the management of lung cancer patients. Considering all the limits of such diagnostic techniques, an aggressive approach to lung neoplasm imply an increase both in explorative thoracotomies and in radical or palliative intraoperative procedures. Our study includes 55 explorative thoracotomies performed on 206 surgical operations for lung cancer. The patients of E.T.'s group couldn't undergo surgical resection in 28 cases because of direct tumoral mediastinal diffusion, involving cardio-pericardial wall and/or great vessels; in 20 for extensive nodal mediastinal diffusion, in 3 patients for pleural dissemination, and 4 had unresectable chest wall involvement. Postoperative mortality rate was 3.6% vs. 5.5% recorded in resected patients; postoperative morbidity rate was 9%. During explorative operations became possible to define more exactly diagnosis and, through palliative procedures, to improve life quality: in fact we performed tumor histology correction or settlement (12/55 P.ts), pericardiotomy for pericardial effusion (5/55 P.ts), pleurodesis or pleurectomy when pleural effusion was present (16/55 p.ts), intercostal neurolysis in involved chest wall areas (4/55 p.ts).
