Combined laparoscopic-colonoscopic approach for the removal of a migrated intrauterine contraceptive device penetrating the sigmoid colon

摘要

Uterine perforation is a rare but potentially life-threatening complication associated with the use of intrauterine contraceptive devices (IUDs). Following perforation, the IUD can migrate to the peritoneal cavity or even perforate several adjacent organs. Migration to the sigmoid colon is extremely rare. We present the case of a 28-year-old woman who had an IUD inserted soon after delivery. The patient again became pregnant, but no IUD could be detected in routine examinations. After an asymptomatic interval of 3 years, the patient suffered acute abdominal pain. Initial laparoscopy elsewhere revealed the IUD attached to the sigmoid colon, but extraction was not possible. The patient was referred to us for further treatment. Under general anesthesia, laparoscopic exploration of the abdomen was performed. The IUD had perforated the sigmoid colon and was firmly fixed. In order not to injure the sigmoid colon, laparoscopic mobilization of the IUD was assisted with a “rendez-vous” sigmoidoscopy. The IUD was removed transanally with laparoscopic and sigmoidoscopic assistance, and the patient was discharged within 24 h after the operation. Insertion of an IUD necessitates regular checks to confirm the device’s correct position. Migration of an IUD warrants prompt laparoscopic removal, even in asymptomatic patients.
