Management of giant hydatid cysts: a tertiary centre experience

Hydatid cyst (HC), the most parasitic disease of the lung, is still an important health problem in Tunisia. In this study, we reviewed our experience in a surgical management of 33 patients with giant pulmonary hydatid cyst (GPHC) (diameter ≥ 10 cm). Between 1998 and 2019, a total of 33 patients with GPHC were operated in the Thoracic Surgery Department in Abderrahmane Mami Hospital. Seventeen were males (51.51) and 16 were females (48.48%). The median age was 33.9 years (range 7–83 years). The diameters of the cyst ranged between 10 and 20 cm (mean 13.15 cm). The most common symptoms were chest pain (63.63%) and cough (33.33%). Imaging showed a single GPHC in all cases. GPHC was intact in 75.75% cases and complicated in 24.25% cases. Posterolateral thoracotomy was performed in 27 cases (81.81%). For the residual cavity, parenchyma-saving procedures were performed in 54.54% and anatomical resection was performed in 45.46%. Morbidity was low, and no mortality was seen. GPHC are considered more difficult to treat surgically than small cysts; parenchyma preserving should and could be the surgical method of choice with a good prognosis. The decision of anatomical pulmonary resection is taken in per-operative when conservative surgery is not possible.
