[The management of intra-, and post-operative air-leakage].

The intra-operative air-lekage usually is found in the operation for emphysematous patients with insufficient separation of the lobar fissure. To those, thoracic surgeons should be careful on making a reasonable line of separation between two lobes. Moreover, after the lobectomy the wide lack of visceral pleura should be repaired absolutely by the various techniques. Postoperatively if the air-leakage would be severe, re-thoracotomy will be needed for the closure of the portion of the air-leakage.
