Cervical dilatation with Lamicel in first trimester therapeutic abortion.

Preoperative treatment with Lamicel tent for first trimester therapeutic abortion was evaluated in an open randomized trial and compared with no treatment. Measured by the lowest Hegar moved through the internal os without resistance, the Lamicel group had significantly higher cervical dilatation than the control group (8.2 mm vs. 5.8 mm; P less than 0.001). One perforation was observed in the Lamicel (n = 270) group compared to six in the control group (n = 359) (not significant). There was no difference between the groups in the frequency of readmissions to the hospital. During one year of clinical experience with pretreatment of elective abortion with Lamicel per- and postoperative complication rates were not reduced.
