In this study we evaluated treatment outcomes of pulmonary hydatic disease in our Department.Methods: Patients admitted with pulmonary hydatic cyst from 1981 to 2008 enrolled in this study and demographic data, site and number of cysts, diagnostic methods, type of operations, outcomes and rate of recurrence were statistically analyzed.Results: In 1024 patients, mean age was (30.6±16.1) years and M/F=1.09. The most common symptom was cough (55.1%).Only 1% was asymptomatic. 53.8% had right side involvement, 40% had left side involvement and 6.2% had bilateral disease. Inferior lobe was the most common involved lobe. The cyst was intact in 539 (52.6%) patients and other, were complicated or perforated. The most common surgical technique was removing the cyst membrane without resection of pericyst and closure of orifice of air ways (67.2%). The cyst was enucleated in 21.2% and parenchymal resection was performed in 10.3%. The mortality rate was (0.2%) and morbidity occurred in 8.4% of patients. The most common complications were residual spaces with prolonged airleak and wound infection. The recurrence rate was 2.5% mostly managed by surgery (82.6%).Conclusion: The best treatment for pulmonary hydatic cyst disease is surgery with low mortality and morbidity. The most common and acceptable treatment is extraction of cyst membrane without manipulation of pericyst and closure of small air ways. Pulmonary resection should be reserved for complicated forms of disease. %U
