This study was made to clarify the result of surgical treatment and the choice of surgical procedures for the open negative cases. The material of this study consisted of 669 cases with open negative cavity among 4, 133 cases who had undergone the operation in 1965 and 1966 at 43 institutions belonging to the Tuberculosis Research Committee (RYOKEN) and had been observed for the period of at least 6 months post-operatively. In this study, the open negative cases were defined as the cases with tuberculous cavity which had showed the negative sputum for the period of at least 6 months by monthly examination.<BR>The successful cases, negative sputum cases, death cases an d post-operative complication cases used as indicators in the evaluation of the result of surgical treatment were defined as the same ones as in our previous several reports.<BR>Comparing the result between the c a ses with negative sputum for more than 6 months and the cases with negative sputum for less than 6 months, the complication rate was significantly higher in the former than in the latter, although there was no difference in the other indicators between the both groups (Table 1).<BR>In the open negative cases, the ratio o f male to female was 71.7% to 28.3%, and 40.0%of these cases were in the age group below 29 years, 49.8% were in the age group of 30 to 49 years, and 9.8% were in the age group above 51 years. The rate of the cases with preoperative %VC less than 50 was 7.2%, that with %VC 51 to 70 was 19.8% and that with %VC more than 71 was 73.0%. The figures of their pre-operative background factors w ere found to be almost the same in all the cases operated upon in the same period. Dividing these cases into 3 groups by the size of cavities, 26.0% had the cavity less than 2 cm, 40.5%2 to 3 cm and 33.5% 3 cm and over in the greatest diameter (Table 2).
