Three step, keep it simple and safe technique for enucleation of pulmonary hydatid cyst

Objectives: Cystic echinococcosis is a zoonotic parasitic infection caused by larval stages of the cestode Echinococcus granulosus , and is an uncommon infectious disorder in human beings, but when present, the liver is the most common location of the echinococcal cyst (>65%), followed by lungs (25%). The slow-growing nature of cysts is responsible for their late presentation, usually as complications such as cyst rupture, secondary infection, suppuration, and pneumothorax. Cyst rupture may lead to an abrupt onset of chest pain, hemoptysis, cough, and fever. Urticaria and wheezing may arise because of hypersensitivity to fluid from a ruptured cyst, which may be life-threatening, so a pulmonary hydatid cyst needs proper emergency management, and delay in management contributes to a sequence of complications, which, if not taken care of may be life-threatening. Materials and Methods: Pulmonary hydatid cysts can be safely operated on with low morbidity and negligible mortality rates. We relate to share our experience of 55 cases of pulmonary hydatid cyst and its surgical management, keep it simple and safe (KISS) technique of enucleation of hydatid cyst and obliteration of residual cavity devised by amalgamation of available techniques for lung cyst removal. Results: By our technique, we achieved maximal conservation of functional pulmonary parenchyma with no post-operative air leak and fatality with no recurrence. Conclusion: The KISS technique has maximal benefits compared to alternative techniques, illustrated by others with minimum morbidity and no mortality. Technique leads to maximal pulmonary parenchyma preservation with no post-operative air leak and no recurrence.
