Levonorgestrel-containing intrauterine contraceptive devices, marketed as Mirena (Bayer HealthCare Pharmaceuticals, Inc. Australia) are widely used in contemporary gynecology, primarily as an effective method for contraception and for control of menstrual disorders like menorrhagia and dysmenorrhea. In this article, the authors report 2 cases of Mirena migration following intrauterine insertion by general practitioners (family physicians). In the first case, the contraceptive device had moved to the patient’s right iliac fossa just anterior to the cecum and, in the second, within the peritoneal cavity close to the left leaf of the diaphragm. Both patients underwent uneventful laparoscopic retrieval of the devices.
