The increase in the diameter of the cyst in younger ages was correlated with higher lung tissue elasticity and the delay in diagnosis because of delayed symptoms in these patients. Although postoperative complications occurred in 19.1% of patients, all were managed by conservative measures, and there were no indications that the affected lung should have been treated with resection instead of a parenchyma-saving operation.

Background: Echinoccosis is an endemic disease throughout the world. We reviewed a series of 26 bilateral lung and liver hydatid treated surgically via median sternotomy and either phrenotomy or laparotomy.Aims: This study was conducted to emphasize the importance of one-stage operation via median sternotomy for multiple hydatid cysts. Materials and Methods:This study is a retrospective review of our surgical skills for treatment of hydatid cysts. From January 1990 to January 2001, 173 patients were operated for hydatid disease in Heybeliada Thoracic Surgery Center. Twenty-six (15%) of them had bilateral lung hydatid cysts including 17 concomitant liver cysts. Median sternotomy was performed in all of 26 cases and phrenotomy was commonly used to remove concomitant liver cysts at the same operation. Cystotomy without capitonnage was the most common operative procedure for both lung and liver cysts.Results: There was no operative and postoperative death. Post-operative complications occurred in only two patients; these were atelectasis and wound infection. The mean follow-up was 7.3 years (ranging from 1 to 12 years). No recurrence was recorded both in lung and in liver.Conclusions: One-stage operation using median sternotomy and phrenotomy should be preferred to stage thoracotomies in suitable cases with multiple hydatid cysts. Cystotomy without capitonnage and closure of the bronchial openings can be an alternative procedure in hydatid disease surgery.
