十二指腸乳頭部癌切除後単発性肺転移の1例

Solitary Pulmonary Metastasis from Carcinoma of the Ampulla of Vater after Pancreatoduodenectomy；Report of a Case

はじめに　十二指腸乳頭部癌の根治術後に肺転移のみで再発し，肺切除を行えた症例の報告は少ない．単発性肺転移で再発した十二指腸乳頭部癌に対して肺部分切除術を施行した症例を経験したので，文献的考察を含めて報告する．

A 74-year-old woman had underwent pancreatoduodenectomy for a carcinoma of the ampulla of Vater. After 3 years of the operation, chest computed tomography （CT） scan showed a solitary nodule in the right posterior segment （S2）. Under the diagnosis of solitary pulmonary metastasis, we performed wedge resection for the right S2 lesion under video-assisted thoracic surgery （VATS）. Pathological diagnosis was the metastasis of carcinoma of the ampulla of Vater. One year later, chest CT scan showed another solitary lesion in right superior segment （S6）. Wedge resection was performed again for the right S6 nodule, which was also diagnosed as a metastasis.
