エキノコックス症による縦隔・肝臓病変に対する一期的手術

Simultaneous Resection of Mediastinal and Liver Hydatid Disease

イヌやキツネを媒介して感染するエキノコックス症の本邦での発生は年間10～30例であり，まれな疾患である．多くは肝臓や肺に感染病巣を形成するが，縦隔病変は非常にまれで，その0.1％以下ともされる1）．われわれは，エキノコックス症による縦隔と肝臓の病変に対し一期的切除手術を行った．同様の報告は認めず，ここに報告する．

Cystic echinococcosis is an uncommon zoonosis in Japan. Typical location of the cyst is the liver and the lung. Mediastinal hydatidosis is found in less than 0.1％ of all hydatid disease patients. We report a rare case of 68 years old male with mediastinal and liver hydatid cysts. Serological test confirmed the diagnosis of hydatidosis. The patient underwent complete resection of mediastinal and liver cysts successfully. Postoperative follow-up for two years has not shown any signs of recurrence. Simultaneous resection of the cysts in different sites including mediastinum is rare and has not been reported in Japan. Hydatid disease is an important differential diagnosis for patient who has cryptogenic liver cyst and history of contact to wildlife or unsterile water.
