Intussusception secondary to endometriosis of the cecum.

introductionIntussusception in adults is a rare cause of bowel obstruction. Endometriosis of the bowel is also a rare entity that can be the cause of bowel obstruction. Here, we report a rare case of intussusception secondary to endometriosis of the cecum. PRESENTATION OF CASE: A 40-year-old woman presented to the hospital with a one-week history of intermittent epigastric pain. On physical examination, there was a soft, round non-tender palpable mass in the right flank and abdominal computed tomography scan revealed an intussusception. We made the diagnosis of ileo-colic intussusception and performed ileocecal resection. The surgical specimen revealed a round submucosal cystic mass in the cecum and the histology showed endometriosis of the cecum. DISCUSSION: Intussusception in adults is a rare entity present in just 1% of all patients with bowel obstruction, and 5% of all intussusceptions. In general, intussusception in adults has a pathologic lesion as the lead point and the lesion is a malignancy in 20-50% of the cases. Thus, the treatment of an intussusception in adults should be operative. Endometriosis of the bowel is a rare cause of intussusception. Small endometriosis lesions of the bowel are unlikely to cause symptoms; however, in patients presenting with bowel obstruction, urgent treatment is indicated.

conclusionIntussusception in an adult is a rare cause of bowel obstruction and intussusception caused by endometriosis is also rare. Although rare, the diagnosis of endometriosis as a cause of intussusception must be considered as part of the differential diagnosis.
