RESUMEN
A clinical study of 71 cases of pulmonary tuberculosis that had had surgical resection during the period of 7 years and 6months from January 1989 to June 1996 in National Masan Tuberculosis Hospital. The results were as follows : 1. The ratio of male to female was 3.7 : 1 and in the age incidence the fourth decade was 22%, the third decade 15%. 2. Although medical treatment was performed for more than 3 to 6 months, preoperatively the conversion failure rate of positive sputum to negative state was 66.2%(47 cases). Of the failure cases, multiple-drug-resistant(MDR) patients were 41 cases(87.2%). 3. In MDR group, preoperatively conversion failure rate was 71.9%. 4. From the view of indication for lung resection on the radiographic finding, cavitary lesions were 43 cases(60.6%), destroyed lung lesions were 24 cases(33.8%). 5. The incidence of postoperative complication was 28.2%(20 cases). All cases were MDR group and the most common of complication was tuberculosis spreading. 6. In bilateral lesion, incidence of postoperative tuberculosis spreading was 25%(7 cases). Of the 7 cases, there was the cavitary lesion in 6 cases(86.7%). 7. Total conversion rate of AFB positive sputum to negative state related to resectional sugery was 76.6% and in MDR group conversion rate of AFB positive sputum to negative state was 73.2%. Conversion rate of MDR group with bilateral lesion was the lowest(60%). Conversion rate of drug-sensitivity group was 100% regardeless of lesions site. In conclusion, despite of long-standing medical treatment, it is difficult to converse sputum-positive to negative state in multiple-drug resistance patients and that increases postoperative complications such as tuberculosis relapse as a lack of appropriate drugs postoperatively. Postoperative conversion rate of sputum-positive to negative state was decreased in multiple-drug resistance patients. Because multiple-drug resistance patients have increased due to several factors in Korea, it is important to prevent spreading of multiple-drug resistnce patients through the aggressive operative treatment. When the first medical therapy is fail or drug-resistance is found, operative treatment should be considered with the secondary medical therapy. The operation should be aggressively attempted even though at first medical treatment if indicated.
