Abstract: Although the true prevalence of adolescent endometriosis is unknown, at least two thirds of adolescent girls with the chronic pelvic pain or dysmenorrhea being unresponsive to oral contraceptive (OCP) and non-steroidal anti-inflammatory drugs (NSAIDs) will be diagnosed with endometriosis at the time of diagnostic laparoscopy. Compared with adult endometriosis, adolescent endometriosis has certain clinical features. The main manifestations are dysmenorrhea and chronic pelvic pain, often accompanied by gastrointestinal and urinary symptoms. About 48% of patients with adolescent endometriosis have psychological disorders, mainly manifested as anxiety or depression and so on. The risk factors of adolescent endometriosis include reproductive organ malformation, early menarche, family history, maternal pregnancy-related diseases and so on. Diagnosis should be combined with the history, clinical manifestations, high-risk factors, gynecological examination, pelvic ultrasound and/or MRI. Laparoscopy and biopsy are the standard for diagnosing definitely adolescent endometriosis. The treatment method of adolescent endometriosis should be based on the comprehensive consideration of the age, symptoms, stages and side effects of medicine, which includes drug therapy, surgery and postoperative adjuvant drug therapy. It is necessary to take the individual treatment and long-term management for those patients with adolescent endometriosis.
