Case of rapid formation of intraoperative pulmonary pneumatocele after lobectomy.

Pulmonary pneumatocele that forms immediately after pulmonary resection is extremely rare. We report a case where a pneumatocele was rapidly formed in the left lower lobe immediately after left upper lobectomy. We noticed massive and persistent air leakage through a chest tube immediately after we closed the chest. Therefore, we re-opened the chest and incised the cyst wall. The air leakage point was cauterized and covered with a polyglycolic acid sheet and fibrin glue. To the best of our knowledge, this is the first case of newly developed pneumatocele immediately after lobectomy.
