A 74-year-old male was admitted to our hospital because of left pneumothorax with persistent air leakage. He had undergone negative pressure drainage, chemical pleurodesis and transbronchial embolization in another hospital. Chest X-ray and CT scan showed collapse of the left lung and a defect of the pleura in the left lung S9. Patch closure was performed for the round pleurobronchial fistula (35 x 35 mm in size) using polyglycol acid felt and fibrin glue. But as severe air leakage was observed again about 24 hours after surgery, omentopexy was performed. The postoperative course was uneventful, and he was discharged 17 days after the second surgery.
