[Operative termination of pregnancy between 12 and 14 weeks' gestation: influence of the operator's experience]. / Particularités techniques de l'IVG instrumentale entre 12 et 14 semaines d'aménorrhée: influence de l'expérience de l'opérateur.

ABSTRACT

OBJECTIVE: To assess the feasibility of operative termination of pregnancy between 12 and 14 weeks of gestation and the role of the operator's experience in physicians previously unfamiliar to this technique. MATERIALS AND METHODS: A prospective study of 251 operative terminations of pregnancy, from July 1st, 2001 to January 31st, 2002, and from May 1st, 2002 to October 31st, 2002, in order to assess the role of operator's experience. 104 terminations between 12 and 14 weeks were compared to 147 terminations at earlier gestational ages. All patients received cervical ripening with 400 mcg oral misoprostol 3-4 hours before operation performed under general anesthesia. Evaluation criteria were duration of operation, need for use of forceps, and complications uterine perforation, cervical laceration, bleeding > 500 ml and need for blood transfusion. RESULTS: There was no difference in the rate of operative complications between terminations before and after 12 weeks. The duration of operation was slightly longer after 12 weeks than before (12.9 +/- 6.7 min versus 11.1 +/- 2.8 min.; p < 0.05). Forceps use was 0.7% before 12 weeks, 20% between 12 and 13 weeks, and 59% between 13 and 14 weeks (p < 0.01). There was no difference in the complication rate or in the need for forceps according to the operator's experience. The perceived difficulty in cervical dilatation was higher in early experience than in experimented operators (19.6% versus 5.2%; p < 0.05). CONCLUSION: Operative termination of pregnancy is technically feasible beyond 12 weeks without dramatic increase in operative complications. Technical skill can be acquired in a short time interval.
