RESUMO
Adenomyosis is a common disease that affects many premenopausal women. Two patients with adenomyosis, aged 51 and 42 years, presented with dysmenorrhea and increased menstrual volume. They refused laparoscopy or laparotomy surgery and were not eligible for the levonorgestrel-releasing intrauterine system (LNG-IUS). The first patient underwent endometrial ablation and subcutaneous etonogestrel (ENG)-releasing implant placement at the same time. Her symptoms of dysmenorrhea and heavy menstruation improved significantly. When serum follicle-stimulating hormone (FSH) and estradiol (E2) levels suggested menopause, the ENG-releasing implant was removed. However, her abdominal pain recurred and was relieved by medication. For the second patient, an ENG-releasing implant was placed first, and her dysmenorrhea and heavy menstrual volume were relieved. However, the bleeding pattern changed from regular bleeding to prolonged bleeding, which troubled the patient. Endometrial ablation was performed 4 months later to solve the problem. Both patients had improved symptoms and were satisfied with the treatment. For patients with adenomyosis who refuse surgery and are not candidates for the use of LNG-IUS, an ENG-releasing implant combined with endometrial ablation may be an effective alternative.
