Conservative Surgical Management for Pulmonary Hydatid Cyst: Analysis and Outcome of 148 Cases

Background. Hydatid cyst (HC) disease is endemic in many developing countries, like Yemen, Egypt, and Saudi Arabia, especially in the rural regions.The disease has a variable clinical courses and even might be asymptomatic for many years. Objectives. In giant and large pulmonary hydatid cysts, pulmonary resection is the usual method of surgical treatment. In this study, we aimed to evaluate the lung conservative surgery in treatment of cases with giant and large hydatid lung cysts, as an effective method of management. Patients and Methods. Between January 2009 and August 2014, a total of 148 patients with pulmonary hydatid cysts were operated and their data was reviewed retrospectively and analyzed. Out of these cases, 52 (35.14%) cysts with more than 10 cm in diameter and 36 (24.32%) cysts with 5–9 cm were regarded as giant and large hydatid lung cysts, respectively. The small cysts less than 5 cm were presented in 8 (5.4%) cases only; other cases had ruptured cysts. Preservation of the lung tissues during surgery by cystotomy and Capitonnage was our conservative surgical methods of choice. Results. Eight patients developed bronchopleural fistula (BPF); of them, 4 BPFs have healed with chest tube and physiotherapy, but in the other 4 patients reoperation was done for the closure of persistent BPF. No mortality was observed in the present study. Conclusion. We conclude that conservative surgical procedure can achieve complete removal of the pulmonary hydatid cyst. Enucleation of the intact huge cysts is safe. Careful and secured closure of the bronchial communication should be done by purse string or figure-of-8 sutures, with or without Teflon pledgets. These simple procedures are safe, reliable, and successful.
