Perforation of the uterus by an intrauterine contraceptive device (IUCD) is not a rare complication with this means of birth control. However, perforation of the colorectum by an IUCD is extremely unusual. Herein we report a case of a 33-year-old female in whom a Copper-T IUCD migrated and subsequently perforated the rectum after she had received painless insertion of the device 3 years previous. Colonoscopic retrieval was tried but failed; thus. a laparotomy was necessary to remove the IUCD. The outcome was satisfactory.
