Surgical treatment of active and sequelar forms of pulmonary tuberculosis.

BACKGROUND

The incidence of tuberculosis has risen since 1990, and in some countries, the resistant forms are becoming more and more frequent. Surgical treatment is once again needed to manage these problems. The purpose of this study was to analyze the indications and results of resection, which we performed for pulmonary tuberculosis.

METHODS

From 1980 to 1997, 477 patients were operated on for thoracic or intrathoracic tuberculosis in Laennec Hospital, Paris (259 suffered lung diseases). There were 165 women and 94 men, aged 25 to 86 years (mean 46 years), from Europe (n = 148), North Africa (n = 65), Subsaharian Africa (n = 34), Asia (n = 7), and the West Indies (n = 5). This population was reviewed concerning the lung tuberculosis (sequelae or active lesions), the indications of lung resection, the type of resections performed, and the results at 1, 6, and 12 months.

RESULTS

Active lesions were present in 97 cases and sequelae in 162. Surgery was performed for a therapeutic purpose in 104 patients with sequelae, and in 10 patients with active tuberculosis (pneumonectomy, n = 19; pleuropneumonectomy, n = 19; lobectomy, n = 54; and segmentectomy, n = 22). Surgery was performed for a diagnostic purpose in 54 patients with sequelae, and in 87 patients with active lesions (lobectomy, n = 32; segmentectomy, n = 19; wedge resection, n = 94, of which 11 performed by video-assisted thoracoscopy since 1991). One patient died after pleuropneumonectomy. We observed 25 complications: empyema, n = 7; hemothorax, n = 2; prolonged air leaks, n = 14; and pneumopathy, n = 2. All patients with active lesions subsequently were given antitubercular drugs. Follow-up was 100% at 1 month, 57% (n = 92) and 77% (n = 75) at 6 months for patients with sequelae and for patients with active lesions, respectively. All were asymptomatic with a normal chest roentgenogram. The number of operations for active lesions is increasing over the years, while it is decreasing for sequelar lesions.

CONCLUSIONS

In our department, surgery is being performed more frequently to make a diagnosis in cases of active tuberculosis, and to treat complicated lesions in case of sequelae. Lung resection for active tuberculosis evolving under treatment or for drug resistance was rare. However, our study confirms the good results commonly obtained by surgery and supports the idea that surgery may help eradicate tuberculosis when social and economic circumstances render its medical management difficult or hazardous.
