Video-assisted Thoracoscopic Surgery (VATS) with mini-thoracotomy for the management of pulmonary hydatid cysts

Background: Hydatid cyst is an endemic infectious disease. Various modalities have been provided to approach hydatosis. This article reports a 20-years-experience of a new minimally invasive technique for the management of solitary pulmonary hydatid cysts using video-assisted thoracoscopic surgery (VATS) with mini-thoracotomy. Methods: We reviewed the medical records of patients who underwent unilateral or bilateral single pulmonary hydatid cyst excision using VATS with mini-thoracotomy. All patients were managed by the same surgeon over the period from January 1996 till January 2015. Results: The study involved 120 patients aged between 11 and 74 years (median age =30 years). The overall number of conducted surgeries was 130 (10 patients needed two surgeries). No deaths were reported during or after surgery. No recurrences were seen in the follow-up period that ranged between 10 and 30 months. Three patients (2.3% out of the 130 surgeries) developed post-operative complications: one patient had prolonged air leak and two patients developed empyema. Conclusion: VATS with mini-thoracotomy is an effective and safe option for managing intact or ruptured solitary pulmonary hydatid cysts. Further studies in controlled prospective design are needed to compare this approach to other modalities of management.
