Colorectal penetration by two intrauterine devices

A colonoscopy was performed as part of a colorectal screening program on a 77-year-old female with positive fecal occult blood test. During withdrawal, two metallic elongated foreign bodies, around 20 mm in length were found pinned into the transverse colon and rectal wall. A computed tomography with multiplanar reconstruction showed two metallic density T-shaped foreign bodies that resembled intrauterine devices (IUDs) that penetrated the intestinal wall , which ruled out other complications. The patient confirmed a previous loss of an IUD device 35 years previously and underwent a second IUD insertion a few years later. She refused another colonoscopy for endoscopic removal as she did not have any symptoms in the past.
