The purpose of this study was to evaluate our adolescent patient population who had received a levonorgestrel intrauterine system (LNG-IUS) at or after the time of endometriosis diagnosis, and determine efficacy of the LNG-IUS in regards to pain and bleeding on follow-up exam. Retrospective cohort study. Pediatric Adolescent Gynecology Clinic and Children's Hospital in a metropolitan area. Adolescent patients age 14 22 with pathology-proven endometriosis who had the LNG-IUS placed during the course of their treatment for this disease. Patients were divided into LNG-IUS placement at the time of surgical diagnosis versus placement some time after diagnosis. Pain and bleeding were assessed by follow-up exam. Pain was classified at each follow-up visit as either none, minimal, moderate, or severe. Bleeding was classified as none, irregular spotting, irregular bleeding, or daily bleeding. The majority of patients (67%) required additional hormonal therapy for pain and bleeding suppression. Time to bleeding suppression and pain suppression was sooner in the group with interval time between surgical diagnosis and LNG-IUS placement, compared to LNG-IUS placement at the time of surgery (2.4 months vs 5.3 months until bleeding suppression, and 3.8 months vs 4.8 months until pain suppression), although statistical significance was not achieved. The LNG-IUS is an option for treatment of endometriosis in adolescents. As pain is the main problem associated with endometriosis, LNG-IUS placement is beneficial at the time of surgery when it is diagnosed. A prospective study is needed for further assessment of outcomes.
