Broncheiectasis is not an infrequent disease in Korea and is defined as irreversible abnormal dilatation of one or more bronchi. Bronchographyis the definitive method of establishing the diagnosis, extent, and severity of bronchiectasis and its performance is essential to the surgeon before the operative procedure is begun.Retrospectively we reviewed 131 patients of bronchiectasis diagnosed by bronchography during the recent 5 years from January, 1982 to December, 1986 and obtained the following results : 1. Male to female ratio was 64:67, and peak incidence was between 21 and 40 year of age with 31.9 of mean age. 2. Chronic coughing, productive sputum, and blood-tinged sputum or hemoptysis were the three predominant symptoms, and duration of the symptoms was less than 5 years in 67.9%. 3. Among tepresumptive etiologic factors, pulmonary tuberculosis was the most common one. Interestingly, bronchial obstruction due to tracheal cancer, bronchial adenoma, and right upper medias inal neurofibroma were also present in one case each. 4. In 91.6% of patients, plain chest film was abnormal, and one of the more unusual abnormal fingings was typical right middle lobe collapse. 5. Left ower lobe, lingular sement, and right lower lobe were the three most frequent sites of incolcement. 6. Among the basal segments, the superior segment was involved in half of the incidence because its anatomical relationship to the others made natural drainage easy. 7. Cylindrical type was the most common bronchographic finding.
