◆要旨:左胸腔鏡下に核出した食道GISTの1例を経験した.腫瘍の主座が中部食道の左側壁であったため,左胸腔からのアプローチを採用し,腹臥位にて胸腔鏡下食道腫瘍核出術を行った.心拍動が多少鉗子操作の妨げにはなるものの,腹臥位のため心臓を強く圧排する必要がなく,術中の循環動態も安定しており,安全に手術を行うことができた.食道領域においては右胸腔鏡下手術が行われることが多いが,近年では下部食道に対する左胸腔鏡アプローチの報告もみられる.中下部食道左側壁に主座をおくGISTにおいては,左胸腔鏡下腫瘍核出術が良い適応になると考えられた.
We experienced a case of left thoracoscopic enucleation for esophageal gastro intestinal stromal tumor. The tumor was confined to the left side of the middle esophagus, and the patient underwent thoracoscopic enucleation from the left thoracic cavity. In spite of interruption by cardiac beats, thoracoscopic surgery was performed safely. Prone position surgery ensured the operative field and handleability, anesthetic management. In general, esophageal thoracoscopic surgery is performed from the right thoracic cavity, but there are some case reports about left thoracoscopic approach for the lesions at lower esophagus in recent years. Enucleation under the left thoracoscopic technique may be feasible for small sized GIST located in left side of middle and lower esophagus.
