Bronchopulmonary dysgenesis

The experience with the diagnosis and treatment of bronchopulmonary dysgenesis is presented. Twenty-eight patients were evaluated: 8 with congenital lobar emphysema; 9 with bronchial cyst; 4 with adenomatoidcystic malformation; 4 with pulmonary sequestration; 2 patients with arteriovenous malformation; and 1 pulmonary agenesia. Two patients died in the postoperative period (7.6 percent of postoperative mortally). Two were not operated on, and the remainder had a satisfactory outcome following sugery. The complications and the follow-up of the patients are analyzed. Embriologic considerations are made and the diagnostic and surgical methods used are evaluated.

Tracheobronchoplasties in lung cancer

Seventy-four tracheobronchoplastic procedures were analyzed in a population of 990 pulmonary resections performed for lung cancer between 1954 and 1994. Fifty-four tracheobronchoplasties were performed between 1954 and 1977 without clinical staging. A second group of 20 tracheobronchoplastic procedures were carried out between 1978 and 1994 with prospective staging assessment. These were classified according to stage as follows: stage I, 5; stage II, 4 and stage III, 11. The overall indidence of bronchial fistula was 13.5 percent (10 cases), nine patients in the 1954-1977 group (16.6 percent) and one (5 percent) in the 1978-1994 period. Local recurrence was detected in 8 patients (13.1 percent) out of 61 postoperative survivors in the whole series. However, this figure was markedly reduced (5 percent) in the second group. Overall postoperative mortality was 17.6 percent (13 patients) and was not different in both groups. Five-year actuarial survival curve reached 21.8 percent in the first group and 21.9 percent in the second group. Tracheal and bronchoplastic techniques are useful procedures that can be safely applied to lung cancer surgery. Indications are the following: to extend the limits of resection; to allow resections in limited pulmonary function patients and to perform isolated main stem bronchus or carinal resections.
