Study Objective: To describe a series of intraperitoneal perforated intrauterine contraception devices (IUDs) and to discuss associated findings, methods for diagnosis, and management of this complication. Design: Retrospective review of surgical database between 1998 and 2012 (Canadian Task Force classification II-2). Setting: University medical center. Patients: Thirty-seven women with a perforated IUD in the intraperitoneal cavity. Measurements and Main Results: Nineteen copper IUDs (51%), 17 levonorgestrel-releasing IUDs (LNG-IUDs) (46%), and 1 Lippes loop (3%) were identified. Twenty women (54%) had abdominal pain, 16 (43%) had no symptoms, and 1 (3%) was found to have strings protruding from her anus. Twenty-six women (70%) underwent laparoscopy to remove the IUD, and 6(16%) underwent hysteroscopy along with laparoscopy. Conversion to laparotomy was required in 4 patients (11%). Two IUDs (5%) caused full-thickness rectouterine fistulas that required laparotomy for repair. Dense adhesions were found in 21 women (57%); and of those, 15 (71%) were associated with a copper IUD. Copper IUDs were significantly more likely than LNG-IUDs to be associated with dense adhesions (p=02). Conclusions: Perforated IUDs can be asymptomatic or cause short-term and long-term symptoms. Long-term complications include abscess and fistula formation. Copper IUDs cause a greater inflammatory process than do LNG-IUDs. Even if asymptomatic, we advocate prompt removal of all IUDs that perforate into the peritoneal cavity once they are identified. Laparoscopic surgical removal of an intraperitoneal IUD is a safe and preferred method.
