[Evaluation of different fibroscopic sampling techniques for the diagnosis of isolated peripheral pulmonary nodules. A prospective study of 74 cases in Vietnam].
Isolated pulmonary nodules raise serious diagnostic problems. Combined imaging and endoscopic methods can often avoid exploratory thoracotomy. The situation is different however in developing countries where health facilities and technical availability are quite variable. Bronchial fibroscopy without image guidance can provide the diagnosis is an acceptable number of cases. We conducted a prospective study in 74 patients. After chest x-ray and CT scan of the lesion of interest, bronchial lavage was performed in each patient with brushings samples in 71 and transbronchial biopsy in 68. Riu staining was performed immediately in the endoscopy suite, providing an almost immediate diagnostic approach. The combination of lavage, brushing and biopsy provided a diagnostic yield as good as the brushings and biopsy combination. These endoscopic techniques gave the diagnosis of the specific lesion in 52 cases (70%). Most involved cancer but there were 15 cases of tuberculosis diagnosis, which remains frequent in developing countries.
