[Patients with diagnostic challenging intestinal involvement of the endometriosis].

A considerable proportion of women with endometriosis have intestinal involvement of the endometriosis. Intestinal endometriosis (IE) often results in abdominal pain and thus mimics the symptoms of other bowel diseases, including colon cancer. As a consequence, some women with IE are initially referred to general surgery and treated under suspicion of colon cancer. This case report demonstrates the diagnostic challenges and describes the key symptoms of IE. Women with key symptoms should be referred to a gynaecological department for transvaginal ultrasonography. The optimal surgical treatment for IE is laparoscopically assisted bowel resection.
