Abstract: Intrauterine device (IUD) placement is a safe, effective, long-acting and reversible contraception, which is one of most commonly contraceptive methods in China. Although the complications of IUD placement are very rare, the IUD ectopia may cause serious clinical consequences. Both doctors and IUD receptors should pay enough attention to this complication. The causes of IUD ectopia could be related to the improper operation or the individual factors of receptor. We reported a case of IUD ectopia that IUD was placed during lactation. The emergency laparoscopic exploration was performed under general anesthesia. The ectopic IUD was removed, and uterine lesion was repaired by punctate electrocoagulation. After 3 days of Anti-inflammatory therapy, the patient was safely discharged from hospital. Combined with this case, the literatures on IUD ectopia were reviewed, so as to attract more attention of gynecologists and obstetricians to the high-risk factors and serious consequences of this complication of IUD placement.
