VP62.20: Study of prevalence and clinical features of non‐ovarian located endometriosis

To determine the prevalence and clinical characteristics of endometriosis found in surgical specimen different from ovarian endometriomas and deep infiltrating endometriosis. Retrospective analysis of surgical specimen in women diagnosed with endometriosis not located in the ovaries or in typical places of deep infiltrating endometriosis during the last three years. During 2017-2019 we performed 163 surgical procedures related with endometriosis. 24 of them (14.72%) were diagnosed of non ovarian endometriosis. The most frequent locations were: abdominal wall (N: 9; 5.52%), large intestine (N: 6; 3.68%), appendix (N: 4; 2.45%), vagina (N: 3; 1.84%) and bladder (N: 2; 1.22%). Mean age of woman with non ovarian endometriomas was 41 years (ranging 28-77 years). All of them but two women were under the age of menopause (91.67%). All patients with abdominal wall (N:9) endometriosis had had a clinical suspicion before surgery because of abdominal pain located in a the scar of a prior surgery (e.g. Caesarean section) confirmed by ultrasound and magnetic resonance imaging. In some cases, intestinal endometriosis was a casual finding in the pathological specimens of the mucosa (N:4). One of them related to an adenocarcinoma of sigma, and another to inflammatory bowel disease. Endometriosis found in the appendix (N:4) was always discovered during surgery in the emergency room because of abdominal pain in the context of an acute appendicitis. In two cases, endometriosis appeared as an incidental finding in vagina, diagnosed on vaginoscopy in patients previously treated of deep infiltrating endometriosis. The bladder nodules (N:2) were seen and extracted in a cystography. Endometriosis can be found in other locations different from the ovaries. Clinical features were accordant to its location although some of them were incidental findings.
