[Results of surgery in Mycobacterium avium complex pulmonary disease].
Recently, several studies have revealed the usefulness of surgical therapy for nontuberculous mycobacterial (NTM) disease. We have encountered and taken many opportunities for surgical therapy in Mycobacterium avium complex (MAC) disease. From April 1995 through March 1999, 14 patients with MAC disease underwent 16 pulmonary resections. NTM was diagnosed at our hospital in all subjects according to the criteria of the American Thoracic Society. There were 8 women and 6 men, with a mean age of 54 years. The most common indications for surgery were localized lesion (7 cases), severe symptoms (5 cases) and progressive disease (2 cases). Twelve patients were receiving multidrug chemotherapy, 10 of whom were also receiving clarithromycin. The mean period of preoperative chemotherapy was 17 months. Ten patients had a variety of symptoms, with some combination of cough, sputum, hemosputum, dyspnea, fever and anorexia. About 30% of the symptoms were improved after preoperative chemotherapy. The symptoms disappeared in all except one patient, who underwent pneumonectomy. After surgery, all patients attained a sputum-negative status. Nine patients underwent 11 partial resections, comprising 3 thoracotomies and 8 video-assisted thoracic surgeries (VATS). There was no operative mortality. Re-operation was performed in a patient with bronchopleural fistula after initial surgery. Currently, 2 months after the last operation, we have encountered no other severe complication and no relapse. Surgery may play an important role in treatment of MAC disease. We recommend partial resection with VATS for localized MAC disease.
