Saucerization: a modified uncapitonnage method of surgery for pulmonary hydatidosis.

Abstract

There are contrary opinions regarding the surgical treatment of pulmonary hydatid cysts. We report our experience performing a modified version of uncapitonnage surgery, called "saucerization," for treating pulmonary hydatid cysts. A total of 78 patients with pulmonary hydatid cysts were studied regarding their surgery outcome and the complication rate. The procedure used for cyst evacuation depended on whether the cyst had ruptured. If ruptured, cystotomy was done; otherwise, enucleation was preferred. To deal with the residual cavity in an uncapitonnage manner, we removed the thin margins of the pericyst and closed the bronchial openings at the cavity floor. All patients were followed up at least for 6 months. The intensive care unit stay ranged from 1 to 9 days. Incomplete lung expansion (six patients) was the main postoperative complication followed by wound infection (four patients) and persistent air leak (≥7 days) (one patient). There was one death. Dependence on mechanical ventilation and subsequent septic shock were also observed. The other patients exhibited no complications during the follow-up period. Our experience demonstrated a low complication rate associated with removing the thin margins of the residual cavity and changing the shape of it into a "saucer." The results were satisfactory and comparable to the results of other studies on pulmonary hydatid cysts.
