Intrauterine device removal from the sigmoid colon during a screening colonoscopy.

An intrauterine device (IUD) is a highly effective method of contraception and is associated with few side effects; however, uterine perforation and migration of the IUD to adjacent organs including the colon have been reported. A 54-year-old woman without relevant medical history underwent a screening colonoscopy. A cylindrical foreign body measuring 25×1mm and penetrating the wall of the sigmoid colon was detected, and was easily removed using a snare (●" Fig.1). The foreign body was later confirmed to be an IUD. The woman remained asymptomatic but a computed tomography scan was performed to rule out complications and no sign of perforation was found. Subsequently, the woman reported that she had undergone insertion of an IUD a few months before falling pregnant at the age of 34. She explained that the IUD had not been found inside her uterus when pregnancy ultrasound scans were performed but, despite that, the woman had given birth naturally. Finally, the patient was discharged and was scheduled to undergo the screening colonoscopy, during which a normal mucosal defect closure was observed. IUDmigration to the colonusually requires surgical intervention. Endoscopic IUD removal has been reported from the rectum, which ismainly extraperitoneal. However, we have only found one case involving the sigmoid colon where clips were used to close the wall defect [1]. In circumstances where a thin foreign body has been embedded in the bowel wall for a long time, we believe that endoscopic removal is safe because the fistulous tract collapses spontaneously and does not require mucosal defect closure or additional interventions.
