Thoracoscopic resection for Mycobacterium avium complex

We report 2 cases of thoracoscopic resection for patients with Mycobacterium avium complex (MAC). A 25-year-old female was referred to our hospital because of abnormal shadows in the right lower lung field on chest X-ray. Her chest computed tomography (CT) showed that the lesion was localized in the right lower lobe. She was given a diagnosis of MAC by polymerase chain reaction (PCR) of sputum. Thoracoscopic lobectomy was performed after chemotherapy for 10 months. A 64-year-old female was referred to our hospital because of hemoptysis. Bronchiectasis had been diagnosed in her since the age of 35 years, and then she was given a diagnosis of secondary MAC. Her chest CT showed bronchiectasis, and consolidations were localized in the superior segment of the right lower lobe. Then superior segmentectomy of the right lower lobe under video-assisted thoracoscopic surgery (VATS) was performed. It was reported that surgical intervention is indicated in patients with MAC, when persistent hemoptysis is seen or chemotherapy is ineffective. If the lesion is localized, lung resection under VATS may be a good option in selected patients.
