左肺上葉切除後異時性発生肺癌に対する気管分岐部切除再建

Carinal Resection and Reconstruction for Second Primary Lung Cancer Five Years After the Left Upper Lobectomy

末梢発生の小型肺癌が増加する一方で中枢発生の肺癌は減少し，それに伴い気管支形成術，なかでも気管分岐部切除再建術を行う機会がきわめて少なくなっている1）．われわれは，左上葉肺癌術後に気管分岐部に発生した異時性多発肺癌に対し，肺実質を温存した気管分岐部切除再建例を経験したので報告する．

A tumor was detected at the tracheal carina to the orifice of the left main bronchus in a 66-year-old man who had undergone a left upper lobectomy for lung cancer five years before and was diagnosed as a squamous cell carcinoma. Carinal resection and reconstruction was performed because of the tumor relapse after the treatment by argon plasma coagulator. Carinal resection was performed under the median sternotomy with reconstruction by the montage method. The patient was discharged on the 8th postoperative day without any postoperative complications.
