Extrauterine translocated contraceptive device: a presentation of five cases and revisit of the enigmatic issues of iatrogenic perforation and migration.

Translocation of an intrauterine contraceptive device to an extrauterine site in the peritoneal cavity is an uncommon complication. In cases reported in literature, the timing of extrauterine presentation and the distant sites of translocation often raise the issue of whether iatrogenic uterine perforation or migration of the device was responsible. We present and discuss five referred cases of the extrauterine device inserted in centres outside the University of Port Harcourt Teaching Hospital. The indication for insertion of the intrauterine contraceptive device in the patients (mean age 25.6 years) was contraception in four patients and adhesiolysis for Asherman's syndrome in the fifth. The most common presenting symptom was inability to feel the device's string (in three patients). Four of the patients presented within one month of the insertion. Three of the five translocated intraperitoneal devices were recovered by laparotomy and the forth by laparoscopy. The fifth patient, pregnant, defaulted with the device still retained. We are of the opinion that primary iatrogenic uterine perforation occurs occasionally. Other possible translocatory mechanisms include spontaneous uterine contractions, urinary bladder contractions, gut peristalsis and movement of peritoneal fluid.
