Perforation, Migration, and Omentum Embedding of a Levonorgestrel Intrauterine Device: A Case Report.

The intrauterine device (IUD) is currently one of the most widely used methods due to its great effectiveness. Uterine perforation and migration of the device is one of its most serious complications, although rare. In most patients, it usually occurs at the time of placement and goes unnoticed; however, it can also occur late. The diagnosis is established by imaging studies, preferring abdominal ultrasound, and its treatment should be removal in all cases. We present the case of a 27-year-old woman, with a history of levonorgestrel IUD placement two years earlier, who presented with chronic pelvic pain. During a gynecological consultation, the IUD threads were not evident. An abdominal CT scan showed that the IUD was in the abdominal cavity, so open abdominal surgery was performed where the IUD was found embedded in the omentum and the segment of the omentum containing the IUD was resected. The patient evolved satisfactorily and was discharged 24 hours after surgery.
