Are superficial bullae with broad bases suitable for ablation?

Superficial bullae with broad bases are not suitable for resection, because the residual lung is too deformed to re-expand adequately when we resect them. Therefore, we believe superficical bullae with broad bases are suitable for ablation. It is not clear, however, whether ablated superficical bullae with broad bases remain contracted after treatment or not We examined the morphologic changes of ablated superficical bullae with broad bases on chest computed tomographs. Ten patients with superficical bullae with broad bases that could be identified on computed tomograph underwent ablation using an electrocoagulator. These bullae were examined by chest computed tomograph preoperatively and again one, three and 12 months after surgery. There were no intra-operative complications. Postoperatively, the only complication was prolonged air leak (more than 7 days) in 1 (10%) patient Pneumothorax after the operation presented in 1 (10%) patient Morphologically, a disappearance of air space associated with bulla-wall thickness was observed in 9 (90%) of the 10 heat-ablated lesions and air space decreased in 1 (10%) lesion. Heat ablation proved to be effective in patients with SBBs. Lesions remained contracted for at least one year after the operation.
