Incidentally discovered extrauterine migration of a Lippes loop: should we let it stay?

Intrauterine devices (IUDs), a form of long-acting reversible fertility control, are often preferred for preventing pregnancy. The Lippes loops, made of plastic, are inserted into the uterus via the cervix, fitting into the uterine cavity. The non-medicated (inert) structure of the loop allows for long-term IUD use. Uterine perforation and translocation of the IUD are the most threatening complications. In this case report, we present an asymptomatic 79-year-old woman with a forgotten IUD that migrated into the abdominal cavity and was discovered during her follow-up for lung cancer.
