    Abstract:
    Delta devices, modifications of standard Lippes Loop D and TCu 220C IUDs, were designed for postpartum insertion. A study of the Delta T and the Delta Loop was conducted at Hacettepe University School of Medicine in Ankara, Turkey. The IUDs were randomly allocated to 246 immediately postpartum women (less than 10 min postplacenta). Twelve-month expulsion rates were low for both devices; 3.7 for Delta Loop users and 7.6 for Delta T users. This study analyzed 12-months expulsion rates among women who had Delta IUDs (modifications of the Lippes Loop D and the TCu 220C) inserted immediately after delivery. 122 women received the Delta Loop and 124 received the Delta T IUD. 1 failed insertion and 1 case of mild pelvic pain were reported at insertion for Delta Loop group, whereas 5 women in the Delta T group experienced mild pelvic pain. The proportions of women reporting menstruation-related problems at follow-up were similar for both groups. There were no cases of pelvic inflammatory disease, although 2 women in the Delta Loop group had cervicitis. The 12-month expulsion rate was 3.7 for the Delta Loop and 7.6 for the Delta T. Most expulsions occurred in the 1st month after insertion. The 12-month removal rate for bleeding or pain was 1.1 for the Delta Loop and 1.0 for the Delta T. Continuation rates at 12 months were 93.3 for the Delta LOOP and 90.7 for the Delta T. The 12-month accidental pregnancy rate was 2.1 among Delta Loop users; there were no pregnancies in the Delta T group. These findings suggest that expulsions are minimized and the risks of infection and uterine perforation are not increased when IUD insertion is performed within 10 minutes after delivery of the placenta. The addition of biodegradable suture projections in the Delta devices is considered to signficantly reduce the number of explusions relative to standard loops.
