espanolPresentamos el caso de una mujer de 39 anos, que aqueja dolor abdominal intermitente asociado a gran perdida de peso en 4 meses de evolucion, acude a urgencias con cuadro clinico y radiologico que sugirio obstruccion intestinal. Se realizo laparotomia exploradora resecandose porcion de colon derecho, sigma distal y recto proximal. El estudio histologico de la pieza quirurgica revelo fibrosis de recto-sigma con presencia de glandulas endometriales secundario a endometriosis rectosigmoidea. La endometriosis como afectacion digestiva debe considerarse en el diagnostico diferencial de todas las mujeres en edad fertil con dolor abdominal intermitente u obstruccion intestinal, aunque no tengan sintomas perimenstruales. EnglishWe report the case of a 39 year-old woman with intermittent abdominal pain associated with severe weight loss in four months, who came to the emergency services with clinical and radiological manifestations suggesting intestinal obstruction. The patient underwent a laparotomy with the right portion of the colon, proximal rectum and distal sigmoid colon being resected. Histology of the surgical specimen showed the existence of fibrosis of rectosigmoid with presence of endometrial glands secondary to rectosigmoid endometriosis. Endometriosis with gastrointestinal involvement should be considered in the differential diagnosis of all women of childbearing age with intermittent abdominal pain or bowel obstruction, even without perimenstrual symptoms.
