We have performed pulmonary resection combined with chemotherapy for multidrug-resistant tuberculosis (MDR-TB). Postoperative complications of pulmonary resection for MDR-TB include space problem, prolonged air leak, bronchopleural fistula with or without empyema, chylothorax, and relapse. Indication, surgical technique, postoperative management, and follow-up of reoperation (thoracoplasty and muscle plombage, clousure of bronchopleural fistula, resuture of bronchial stump, open window thoracostomy, and 2nd pulmonary resection) for these complications are described.

Background: According to the 2007 American Thoracic Society/Infectious Diseases Society of America statement on nontuberculous mycobacterial diseases, more evidence for the benefits of adjuvant nontuberculous mycobacterial lung disease surgical intervention is needed before its wide application can be recommended.

Methods: A retrospective review was conducted of 60 consecutive patients who met American Thoracic Society/Infectious Diseases Society of America diagnostic criteria and underwent pulmonary resection for localized nontuberculous mycobacterial lung disease between January 2007 and December 2011. All patients were receiving chemotherapy before resection.

Background: The purpose of this study was to demonstrate our surgical experience for focal bronchiectasis in the setting of modern diagnostic modalities and state-of-the-art medical treatment in a developed country.

Methods: Thirty-one patients undergoing 33 lung resections for the treatment of focal bronchiectasis from 1991 to 2009 were reviewed. The mean age was 54 years.

To assess whether there is any difference in postoperative morbidity and mortality after pneumonectomy between patients with multidrug-resistant tuberculosis (MDR-TB) and patients with non-tuberculous mycobacterial (NTM) infections. Between January 2000 and December 2007, 61 patients with MDR-TB and 60 patients with NTM infections underwent 66 and 64 pulmonary resections, respectively. Of these, 33 patients were analyzed who underwent a pneumonectomy, including 22 patients with MDR-TB (seven right, 15 left) and 11 patients with NTM infections (seven right, four left).

Objective: Because extensively drug-resistant tuberculosis has emerged, adequate control of drug-resistant tuberculosis has become increasingly important. We report on our experience using liberal adjuvant resectional surgery as part of aggressive treatment for multidrug-resistant tuberculosis.

Methods: We retrospectively reviewed the records of 56 consecutive patients who underwent pulmonary resections for multidrug-resistant tuberculosis between January 2000 and June 2007.

We analyzed 8 patients with unresectable locally advanced non-small cell lung cancer who responded to chemotherapy or chemoradiotherapy and underwent complete resection between June 2003 and June 2005. The patients were all male with a mean age of 61 years (range, 42 to 72 years). Histological subtypes included adenocarcinoma in 4 patients and squamous cell carcinoma in 4 patients.

A case of tuberculous psoas abscess complicated during antituberculosis therapy for miliary tuberculosis and successfully treated with surgery was reported. A 20-year-old man visited our hospital because of fever lasting for 3 months. Chest radiography showed miliary nodules in both lungs and transbronchial lung biopsy revealed granuloma.

We describe a case of chronic tuberculous methicillin-resistant Staphylococcus aureus (MRSA) empyema with bronchopleural fistulae successfully treated by open window thoracostomy followed by thoracoplasty and transposition of the latissimus dorsi muscle. A 69-year old man with a history of artificial pneumothorax for pulmonary tuberculosis was referred to our hospital with fever and purulent bloody sputum. He was diagnosed as having right chronic tuberculous empyema with bronchopleural fistulae.

Objective: Pneumonectomy for complex aspergilloma is associated with high morbidity rates. This study aimed to improve the outcomes of this high-risk procedure by preventing postoperative complications.

Methods: Between April 1999 and December 2004, 25 patients underwent pulmonary resection for complex aspergilloma at our institution.

We describe a case of a large bronchial fistula and empyema after right upper lobectomy that was treated successfully with open window thoracostomy followed by a latissimus dorsi myocutaneous flap and limited thoracoplasty. A latissimus dorsi myocutaneous flap can provide immediate airtight closure of a large bronchial fistula, allowing lavage and curettage of the empyema cavity to reduce the chance of postoperative infection. An important aspect of this technique is that the deepithelialized skin side rather than muscle is sutured to an opening of the bronchus.

Objective: Multidrug-resistant tuberculosis remains a significant health problem. The best available treatment for multidrug-resistant tuberculosis is the combination of pulmonary resection and antituberculous chemotherapy. We herein report the results of pulmonary resection combined with chemotherapy for multidrug-resistant tuberculosis at our institution during the years 2000 through 2002.

Background: Pneumonectomy is considered in the treatment of nontuberculous mycobacterial infections when an entire lung is affected. However, this procedure carries high morbidity. We report on our experience in using pneumonectomy for treating patients with nontuberculous mycobacterial infections.

The condition of a 51-year-old man was complicated with empyema and bronchopleural fistula (BPF) after left upper lobectomy and thoracoplasty for pulmonary aspergillosis. On the postoperative day (POD) 12, the opened bronchial stump was directly closed and covered with a pedicled pectoralis major muscle flap. On POD 66, an open-window thoracostomy was done, because of empyema with Pseudomonas aeruginosa Two years later, we could fill the empyema cavity, and close the multiple BPFs with the transposition of a modified pedicled musculocutaneous (MC) flap and the additional thoracoplasty to gain good quality of life.

Objective: Since the introduction of clarithromycin, it has been assumed that pulmonary Mycobacterium avium complex (MAC) disease can be treated with medication alone. This study examines whether surgery can still play an important role in the management of MAC lung disease in the current era.

Methods: Between April 1993 and January 2001, 21 patients (11 men and 10 women) underwent a pulmonary resection for MAC infection.
