[A Case of Sigmoid Colon Cancer with Rectal Intussusception Treated by Robotic Surgery].

We reported a case of sigmoid colon cancer with rectal intussusception. An 82-year-old woman had anal prolapse. Results of the examination, it was a diagnosis of sigmoid colon cancer with rectal intussusception. The tumor was then repositioned. Based on the above, robotic sigmoidectomy with D3 dissection of lymph nodes was performed. The histopathological diagnosis demonstrated double sigmoid colon cancers and no ischemic change of colon. She has not recurred 16 months later after operation.
