Methodology: Patients diagnosed and treated for hydatid cyst with pulmonary echinococcosis and operated were included. Inhospital as well as hospital records of 180 patients including intact and complicated cysts ranging from 1-20cm in size that were
extirpated and included. Patients diagnosed and treated for hydatid cyst having incomplete medical record and /or lost to

Results: Mean age of patients was 38.59±12.51 years. Mean duration of hospital stay was 11.3±6.1 days. Mean pain on VAS postoperatively was 4.92±2.66. About 102(56.67%) of included patients were male while 78(43.33%) females.

About 58% of cases underwent cystotomy and capitonnage, 17% enucleation and capitonnage while 12% pericystectomy, 4% cystotomy and wedge resection and segmentectomy respectively, 3% lobectomy and pneumonectomy in 2% of cases.
