Two cases of sigmoid colon cancer with intussusception prolapsing through the anus in adults: consideration of preoperative reduction and surgical approaches: case reports

Adult intussusception is a rare condition that is often associated with a high incidence of malignancy.

We present two cases of sigmoid colon cancer with intussusception prolapsing through the anus and highlight the different surgical approaches.
