Prolapse of Intussusception through the Anus as a Result of Sigmoid Colon Cancer

Hiroki Ochiai et al. Case Rep Gastroenterol. .

Abstract

Adult intussusception is rare and most often associated with cancer. We report a case of intussuscepted sigmoid colon into the rectum protruding from the anus of a 47-year-old woman. The cause of the intussusception was sigmoid colon cancer. We removed the intussuscepted part of the sigmoid colon as well as the rectum and regional lymph nodes. The patient recovered uneventfully and there has been no evidence of recurrence of the cancer.
