Surgical Procedures and Postoperative Complications in Patients with Giant and Non-giant Pulmonary Hydatid Cysts

Abstract

There is a challenge over treatment of giant pulmonary hydatid cysts. Therefore, we aimed at comparing the surgical procedures and postoperative complications between patients with giant and non-giant hydatid cysts. In a retrospective clinical study, patients operated for hydatid lung cysts were divided into giant pulmonary hydatid cysts (size> 10 cm) and non-giant hydatid cysts groups. Patients were treated surgically using lung preservation (capitonnage, uncapitonnage and segmentectomy) and lobectomy procedures. A total of 612 patients, 59 (9.6%) in the giant and 553 (90.4%) in the non-giant pulmonary hydatid cysts, were recruited. The most common symptoms in the giant group were cough (100%) and dyspnea (71.2%). These symptoms along with the systemic symptoms and ruptured hydatid cysts were more observed in the giant group (P<0.001). The lung preservation procedures and cyst delivery were more performed in the non-giant group (P<0.001), while lobectomy, needle aspiration and bronchial opening closure procedures were more applied to the giant group (P<0.05). The postoperative pulmonary complications, excluding empyema and anaphylaxis, were more observed in the non-giant group (P<0.001). The patients undergoing the surgery of giant pulmonary hydatid cysts, using lobectomy in comparison with the lung preserving procedures experience lesser postoperative pulmonary complications and total length of hospitalization.
