Post-cesarean section pain secondary to intussuscepting colonic adenocarcinoma

The differential diagnosis for lower abdominal and pelvic pain following Cesarean section includes many causes, such as endometritis, abscess, pelvic hematoma, wound complications, pelvic vein thrombophlebitis, gastrointestinal dysfunction and obstruction. Colonic obstruction secondary to intussusception is a rare cause. We present a case of post-Cesarean section pain in a 26-year-old patient due to obstructing colonic intussusception secondary to colonic adenocarcinoma. Review of the literature failed to identify a previous case report of colonic adenocarcinoma with intussusception presenting early in the postpartum period. The diagnosis was initially made by ultrasound, and later corroborated by computed tomography, barium enema and laparotomy.
