Background:
Colorectal cancer during pregnancy is uncommon. Most patients present in late pregnancy, and the tumor is localized to rectum in up to 85% of cases. Delayed diagnosis due to confusing significant lower gastrointestinal symptoms with pregnancy-associated gastrointestinal changes is a common feature. From the increasing intraabdominal pressure during delivery, a tumor can prolapse throu the anus and develop incarceration and strangulation, but that is seen a extremely rarely,
Case:
A 33-year-old woman was found to have a prolapsing rectal cancer through the anus during delivery, and it progressed to incarceration,
Conclusion:
Colorectal cancer during pregnancy is rare and mostly localized to the rectum. To manage a strangulated rectal prolapse that occurs in labor, consideration should be given to perineal rectosigmoidectomy under general anesthesia. The choice of surgical procedure is controversial if the preoperative diagnosis is not clear.
