Evacuation and bronchial opening closure : the results of 100 surgeries for lung hydatid cyst

الملخص EN

Hydatid cysts are an endemic zoonosis in Iran.

Lung is second most common site or 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 % female.

Patients present by symptoms as cough, sputum, bloody stained sputum, dyspnea, 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 ease 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 F.BOC for lung hydatid cysts .
