Ileocecal intussusception as the initial presentation of endometriosis: case report.

Cecal endometriosis is a rare entity that can present as nonspecific acute abdominal pain and can be complicated by ileocolic intussusception, which is extremely infrequent. We present the case of a 33-year-old woman with no relevant pathological antecedents who consulted for abdominal pain for 5 days, associated with rebound tenderness and abdominal guarding on the right lower quadrant and a palpable mass during the physical examination. Computed tomography was realized and emergency surgery performed due to suspected ileocolic intussusception. The laparoscopic examination identified an ileocolic intussusception associated with a tumor. Conversion to open surgery was needed, and an oncological right hemicolectomy with ileotransverse anastomosis was carried out. Histopathological study reported ileocolic intussusception and a focus of cecal endometriosis. Currently, the patient does not have recurrences. Ileocolic intussusception secondary to deep endometriosis requires great diagnostic presumption in women of childbearing age with acute abdomen diagnosis.
