Surgery for bullous disease of the lung.

Abstract

Between July 1986 and December 1990, 22 patients underwent 23 operative procedures for bullous disease at Harefield Hospital. Their ages ranged from 21 to 71 years (mean 49.8 years). There were 18 males and 4 females. All patients were operated upon for symptoms of exertional dyspnoea. Four patients belonged to functional class IV, 11 to class III and 3 to class II. In 80% of patients, computed tomography was performed as part of the preoperative assessment. The bullae were dealt with in 13 patients on the right side, in 7 on the left and in 2 bilaterally. Six patients were treated by a modified Monaldi procedure and 17 by bullectomy. There was no operative mortality. Mean hospital stay was 14.8 days. Two patients required a second operative procedure during their hospital stay for persistent air leak and pneumothorax. One of these had a Monaldi procedure in the first instance but underwent bullectomy later. All patients improved symptomatically, 10 patients moving up two grades and 12, one grade. Mean FEV1, FVC and MVV were significantly improved postoperatively, but there were no significant changes in RV or TLC. A graduated exercise test was performed in 4 patients. Improvements were seen in ventilation and oxygen consumption at anaerobic threshold and maximum exercise. Surgery for bullous disease improves symptoms by reducing airway obstruction and increasing ventilatory capacity on exercise.
