Evacuation and bronchial opening closure "the result of 100 surgeries for Lung Hydatid Cyst"

ABSTRACT

Hydatid cysts are an endemic zoonosis in Iran. Lung is second most common site of involvement [10-15%]. There are different methods for hydatid cyst surgery Video Assisted Thoracic Surgery, cystectomy, lobectomy, Evacuation and Bronchial Opening Closure [EBOC]. This is a retrospective study of 120 patients operated between 1368 to 1380[1990 to 2002]. Our patients aged between 3 to 60 years; 62% males and 38% females. Patients present by symptoms as cough, sputum, bloody stained sputum, dyspnca, chest pain in 92% of cases; 4% of patients discovered incidentally, there were 10% of patients with bloody stained sputum; 5% had intact hydatid cysts. All patients were operated via posterolateral thoracotomies. We did EBOC in 100 patients, labectomy in 8 and cystectomies in 5 patients. Wedge resections performed in 7 patients. We did not use Video Assisted Thoracotomy Surgery. Broncho pleural fistula occurred in 2% of patients, that forced us in one case to performing lobectomy, but another case was treated by chest tube insertion. Also there were 2 patients affected with empyema, treated with conservative treatments. Superficial wound infection occurred in 4 patients which was treated with drainage and all of them cured. There were no additional complication in one-year follow up and residual cavity gradually faded, up to 6 months. Evacuation and Bronchial Opening Closure is a safe, simple, and non-invasive procedure; it is applicable in a shorter time compared with other procedures; and then suggest using E BOC for lung hydatid cysts
