Asymptomatic cecal perforation and ileocecal fistula after intrauterine device migration: a case report

Implantation of an intrauterine device (IUD) is a common method for long-term contraception. However, IUDs can cause colon perforation and fistula formation. We report a case of cecal perforation and ileocecal fistula secondary to IUD migration. The present study investigated incidental identification of a missing IUD after 9 years of deployment in a 35-year-old female with a three-year history of infertility. Abdominal imaging revealed a missing IUD. Intracecal perforation and ileocecal fistula consequent of IUD migration were identified during surgical exploration. Limited ileocecal resection was performed as an appropriate and safe surgical option. IUD migration can present with serious complications. Patients considering IUDs should be educated about the importance of regular check-ups to monitor the position of the IUD. Thorough examination should be carried out if a missing IUD string is reported.
