Nd-YAG laser-assisted pulmonary metastasectomy: initial experience from a tertiary care cancer center in India

Pulmonary metastasectomy is recommended for metastatic lung lesions when R0 resection is possible, the primary site is in controlled status, surgery is of low risk, and extrathoracic metastases are absent. We present the initial experiences of laser-assisted surgery (LAS) for pulmonary metastatic lesions from a tertiary care cancer center in India.

All patients undergoing non-anatomical pulmonary metastasectomy between September 2022 and January 2023 for synchronous and metachronous lesions, operated on by a single consultant thoracic oncosurgeon in a tertiary care center of India, were identified from a prospective database. Ten patients with 124 metastatic lesions were included in the study. A hybrid approach (video-assisted thoracoscopic surgery (VATS) with mini-thoracotomy) was performed. Measurements of total lesion volume and lung parenchyma resected were taken from the final histopathological analysis of the intraoperative sample.

LAS was performed for 102 lesions and stapled wedge resection for 22 lesions. Evidence of malignancy was noted in 88/102 (86.3%) of the lesions excised. Patients with LAS had advantages of parenchyma preservation, less postoperative morbidities, and shorter hospital stays.

LAS of pulmonary metastatic lesions addresses more lesions in a single sitting; the bilateral lung lesions can be operated and has parenchyma preserving and good sealant properties.
