Osmotic Dilator Intra-Abdominal Perforation: A Case Report.

BACKGROUND

This report describes an unusual case of a retained hygroscopic osmotic dilator following second trimester dilation and evacuation.

CASE: A 24-year-old woman presented for elective pregnancy termination at 16 weeks gestational age. A cervical osmotic dilator could not be retrieved and fractured on attempted removal. Magnetic resonance imaging showed perforation through the cervix, possibly traversing the peritoneum. Hysteroscopy and laparoscopy were performed to remove the retained dilator. Significant inflammation and mesenteric adhesions surrounded the osmotic dilator, which was successfully removed.

CONCLUSION

This is the first reported case of an intra-abdominal osmotic dilator. Although this device is inert, close follow-up and timely retrieval, possibly with hysteroscopy or laparoscopy, are recommended to minimize the resulting inflammatory response.
