[Developments in surgery of pulmonary metastases].

Two groups of patients between 1977-1986 and 1987-1989 underwent surgery for pulmonary metastases. The most frequent primary sites were the kidney and the colon-rectum. While metastases from testicular cancer have become rare indications, metastases from breast cancer are increasing. Our results show that more metastatic lesions are usually found at operation than indicated by CT scan. The discrepancy amounts to 18% in presumably solitary metastases and increases to 50% if three or more lesions were identified preoperatively. Therefore, bilateral exploration is advocated. Lesions of the posterior lower lobes are more satisfactorily approached by a bilateral transverse incision and sternotomy. The mortality was 1% in the former and 0% in the more recent group of patients.

[Value of diagnostic procedures in fiberoptic bronchoscopy of pulmonary infections].

Fibreoptic bronchoscopy has become an important means of diagnosing infections of the lower respiratory tract, since it a method with few complications, whereas, on the other hand, the conventional non-invasive methods are hardly reliable in respect of diagnostic relevance. Frequent oropharyngeal contamination severely limits the significant assessment of the pathogenicity of cultured microorganisms. The protected specimen brush (PSB) or quantitative cultures of bronchoalveolar lavage (BAL) might be useful in solving this problem. These methods were studied in two prospective trials comprising 123 patients with suspected bronchopulmonary infection and 54 control patients. Both methods were found to be disappointing in respect of sensitivity; moreover, quantitative cultivation did not yield any differences with regard to specificity.
