Translocation of an intra-uterine contraceptive device with sigmoid penetration through an endometriosic nodule.

The intra-uterine device (IUD) is the most common existing reversible contraception. Uterine perforation occurs in 0.6 to 3.4 per 1000 insertions. We describe the first report of IUD translocation and subsequent penetration of the sigmoid through an endometriosic nodule. A 44-year-old gravida 2 para 2 woman consulted for rectal bleeding and melena. Rectosigmoidoscopy revealed ischemic colitis secondary to the use of NSAIDs, which explained the bleeding, but also sigmoid perforation from part of an intra-uterine device. This was discovered by chance. Perforation had occurred though an endometriosic nodule.
