女性自然気胸手術例における臨床的特徴―男性例との比較・検討

Clinical Features in Surgical Cases of Female Spontaneous Pneumothorax；Comparison with Male Patients

気胸は，疫学的には細長体型の若年男性に多く認められ1），女性には比較的まれな疾患とされている．諸家の報告に差はあるが，自然気胸の約12％，続発性自然気胸の約17％を占めるにすぎないとの報告もあり2），またその成因など不明な点もまだまだ多い．

We assessed the clinical features in surgery cases of female spontaneous pneumothorax by comparing them with male patients. One hundred six patients （female/male：16/90）who had undergone surgery for spontaneous pneumothorax between January 2003 and August 2013 was retrospectively studied. Patient background, pneumothorax classification and treatment were assessed. No significant difference was found in patient background and treatment. In pneumothorax classification, the frequency of secondary pneumothorax in females was significantly greater than that in males （p＜0.001）. Additionally, in females, the number of bulla identified during surgery was significantly fewer and the number of recurrences before surgery was more frequent than that in males.
