title: Evaluation of a balloon dilator before second-trimester abortion by vacuum curettage.
abstract: We evaluated the cervical dilator device (CDD), an expanding balloon, as a substitute for laminaria tents before abortion at 13 to 16 1/2 weeks by extraction and vacuum curettage. The CDD was found to be an effective dilator, although it did not appear to have any advantage over laminaria tents when placed overnight and was associated with significant pain upon insertion and an apparent increased risk of endometritis. The present CDD or a subsequent modification may offer advantages over laminaria tents for short-term placement.
