[Local resection of pulmonary lesions by Nd-YAG laser without suturing]

Local excision of 67 pulmonary lesions in 5 patients was performed with the Nd-YAG laser. There were 2 women and 3 men with an average age of 68 years. The patients consisted of three cases of metastatic lung cancer (65 lesions), one hamartoma (One lesion) and one organized pneumonitis (one lesion). The lesion was first enucleated by a contact method using an Nd-YAG laser scalpel, then the crater of the resected lesion in the normal lung tissue was coagulated with a defocused laser beam. The craters of 52 of the 67 resected lesions which were shallow seated in the lung were left open, but the other 15 resected lesions were closed with sutures. Total blood loss was less than 100 ml. There was no bleeding or air leakage (30 cm water pressure) during the post operative days in 4 of the 5 patients, but one patients (one lesion) had to be treated by bronchoscopic endobronchial embolization against a persistent air leak. This lesion was 2.5 cm in diameter and 4 cm deep in the lung on CT. The other lesions were also measured by CT. The tumor size was 1.4 +/- 0.7 cm and the depth was 2.4 +/- 1.0 cm. The Nd-YAG laser is very suitable for local resection of peripheral lung lesions without suturing.
