Surgical treatment of hydatid cysts of the lung: analysis of 405 patients.

OBJECTIVE

The choice of operation, postoperative success and complications of surgery in patients with pulmonary hydatid cysts.

DESIGN

A series of patients seen over 15 years.

SETTING

A university clinic.

PATIENTS

Four hundred and five patients (209 male, 196 female) ranging in age from 4 to 72 years (mean 29 years). Most (367 patients) had isolated lung cysts; 38 had both liver and lung cysts.

INTERVENTIONS

A variety of procedures to remove cysts, including enucleation and capitonnage, wedge resection, segmentectomy, lobectomy and pneumonectomy. Six patients with bilateral cysts were operated on through a median sternotomy approach. Others underwent posterolateral thoracotomy.

MAIN OUTCOME MEASURES

Value of diagnostic tests, the most efficacious approach for cyst removal and recurrence and death rates.

RESULTS

Chest radiography gave a correct diagnosis in 99% of patients. The Casoni and Weinberg tests were discontinued because of high false-negative rates (up to 35%). Hospital mortality was 1.2% and postoperative complications occurred in 5.2%. The recurrence rate was 1.5%.

CONCLUSIONS

Lung-preserving surgical interventions are the treatment of choice for pulmonary hydatid disease. In patients with bilateral cysts, the median sternotomy approach is preferred, and in the patients with right lung disease and coexisting liver cysts the transdiaphragmatic approach is the one of choice to remove cysts in 1 stage.
