[New method for localization of the small ground-glass opacity lesion in resected lung].
A small lesion showing ground-glass opacity (GGO) by preoperative computed tomography (CT) is sometimes difficult to detect after lobectomy when it locates in the central part of the lobe. In order to facilitate to identify the lesion for marking pathological specimen, we developed a new method using CT. After surgery, the resected pulmonary lobe was expanded with airflow through the bronchial stump and the target lesion was examined with CT. The laser beam of the CT on the surface of the lung is used as a guiding line for cutting. Through the application of this method for 2 clinical cases, it was found to be possible to exactly identify the GGO lesion from the surface of the resected lung enabling to visualize a fresh surface of the lesion like a CT image with minimal destruction of the structure.
