This paper reports a case of inguinal endometriosis in which a 2022 Japanese patient developed a mass and menstruation-associated pain in the inguinal region. The authors describe laparoscopically assisted combined resection of the round ligament, performed after dienogest pharmacotherapy failed (dienogest-resistant disease), and note that the inguinal mass was removed along with the round ligament during the operation. Postoperatively, dienogest was continued and no recurrence was observed during follow-up, and the report includes a literature review of laparoscopic surgical treatment of inguinal endometriosis in Japan. As a single case report, the main limitation is that findings are not generalizable beyond this patient. This paper is centrally about endometriosis — specifically dienogest-resistant inguinal endometriosis treated with laparoscopically assisted resection of the round ligament.

Abstract

Inguinal endometriosis is rare and accounts for 0.3% to 0.6% of all cases of endometriosis. Although a few studies have described drug therapy for this condition, inguinal endometriosis is primarily treated surgically. We report a case of inguinal endometriosis in a patient who presented with a mass and menstruation-associated pain in the inguinal region. Dienogest administered as pharmacotherapy was ineffective, necessitating surgical management. The inguinal mass was percutaneously removed along with the round ligament after laparoscopic resection of the round ligament. Dienogest was administered postoperatively, and no recurrence was observed during follow-up. We present a case of inguinal endometriosis, together with a literature review on the surgical treatment of inguinal endometriosis with laparoscopy in Japan.
