Abstract
A 51-year-old woman, who had video-assisted thoraco-surgery (right middle lobectomy) two years prior, was admitted to our hospital. Her serum CEA level rose 1 and a half years after the operation. Half a year later, she complained of abdominal pain and abdominal fullness. A colonic neoplasm was diagnosed. She underwent elective right hemi-colectomy. Many lung cancer digestive tract metastases are well advanced at the time of detection ; indications for surgery are rare. However, in this case elective excision was possible. A literature review is also presented.
