Brief summary

To investigate the most preventable option to reduce primary spontaneous postoperative recurrence.

Detailed description

Pneumothorax is a disease in which air in the lungs leaks into the pleural cavity. It is a disease that occurs most often in young people with active social activities, and it occurs in about 100,000 people in 14 cases. The recurrence rate is as high as 17% to 54%, and the delay of the rehabilitation by the ambulatory with the treatment and prolongation of the hospitalization becomes a problem. It becomes a large failure for the youth who requires early rehabilitation. According to the latest report from the Japanese Society of Surgery, approximately 12,000 pneumothorax surgeries are performed annually in Japan. Many of them applied absorbent material to the surgical stump (coverage technique). However, there are no prospective studies, and efficacy does not appear adequately tested. It is necessary to accumulate prospective data from multiple centers to investigate the coverage technique's real effect.
