Rare case of retained Copper‑T IUCD transmigration, presenting in a pregnant lady with Caecal Perforation Requiring Ileocecal Resection and Ileocolic Anastomosis: A Case report.

Background: Intrauterine contraceptive devices (IUCDs) are effective long‑acting reversible contraceptives but may rarely perforate the uterus and migrate to adjacent viscera, sometimes remaining asymptomatic for years. Case Presentation: A 33‑year‑old woman at 26 weeks’ gestation presented with right iliac fossa pain; fever and tachycardia for 1 day. Intraoperative findings revealed a transmigrated Copper‑T device within the caecum causing dual perforations of caecum requiring ileocecal resection and end-to-end ileocolic anastomosis. Outcome: Maternal recovery was uneventful and fetal viability was preserved throughout the entire hospital stay. The patient was discharged on the 5th postoperative day. Conclusion: Long‑standing retained IUCDs can cause serious gastrointestinal complications and contraceptive failure; prompt surgical management yields favorable outcomes.
