Aim: The purpose of this study is to examine our single stage operation experiences of patients with lung and liver hydatid cyst and to examine the results. Material and Method: Between 2002 and 2011, 29 patients with both lung and liver hydatid cyst were examined. Among those, 21 patients had cysts located on the dome of the liver. Those patients were operated on with phrenotomy through a right thoracotomy. 21 patients are retrospectively examined by reviewing age, gender, symptoms, cyst sizes, operation methods, operation duration, and complications. Results: The age mean was 60,0 +/- 16,72 cm. Of the 21 operated patients, 8 were males and 13 were females. While cough and abdominal pain were the most common symptoms, isolated abdominal pain was observed at 2 patients. 4 patients were asymptomatic. It is found that the average diameter was 7,50 +/- 1,29 cm for lung cysts, 7,0 +/- 1,76 cm for liver cysts. Lung cysts were managed through cystotomy with / without capitonnage or wedge methods. On the other hand, the chosen method for liver cyst was cystotomy and cavity invertion with drainage of subdiaphragmatic area. The average operation duration was 145,0 +/- 15,26 minutes. Prolonged biliary drainage was observed at two patients. There was no mortality. Discussion: The transdiafragmatic liver cyst management by frenetomy via right thorocotomy is a reliable and effective method at patients with simultaneous right lung and subdiafragmatic liver hydatid disease patients.
