[Preliminary experience of use of ultrasonic surgical aspirator for lung limited resection].

The authors reported 8 cases undergone lung limited resections (11 operations) by cavitron ultrasonic surgical aspirator (CUSA). There were 3 cases (6 operations) with multiple metastases in lung, 1 case with single metastasis in lung, 1 case with peripheric lung cancer, 1 case with nodule of tuberculosis in lung, 1 case with lung abscess and 1 case with lung cyst. All the patients recovered well postoperatively. Until now 4 cases with lung metastatic tumors have living well for 3.5, 1, 0.5, and 0.3 years. Ultrasonic Aspiration is very beneficial for lung limited resection: Less blood lose; Simple surgical techniques; and to be able to resect the deep lesions in lung and multiple lung lesions, and avoid lobectomy or pneumonectomy for more preserving lung tissue.
