Objective(S):
Cervical incompetence is an important cause of recurrent pregnancy loss, typically presenting in the second trimester with silent cervical dilation and premature delivery of the fetus. We aimed to evaluate the conception rate and time to conception or failure to conceive after preconceptional laparoscopic abdominal cerclage (LAC).
Study Design:
We conducted this retrospective observational cohort study at a tertiary referral center. Patients who underwent LAC in the nonpregnant state for a second-trimester pregnancy loss between June 2012 and February 2020 were included.
Results:
The subjects were 40 patients with a history of one or more second-trimester pregnancy losses despite the placement of vaginal cerclage, who had undergone LAC before contemplating a future pregnancy. The mean number of second-trimester pregnancy losses before LAC was two per woman. The ages of the women at the time of cerclage ranged from 21 to 42 years. The time to pregnancy, which was the primary outcome of the study, was determined as the number of menstrual cycles before the patient became pregnant after LAC and the number of cycles needed for the patient to achieve her latest pregnancy before LAC. Of the 40 women, 22.5 % were noted during the LAC operation to have a pelvic peritoneal pathology that might have affected fertility, and all such pathologies were treated concomitantly during the procedure. Spontaneous pregnancy rates before and after LAC were 96.4 % and 89.3 % (p = 0.299), and times to pregnancy before and after LAC were 6.3 ± 8.4 and 6.6 ± 8.1 cycles (p = 0.897). Neither difference was statistically significant. In more than 84 % of patients who became pregnant after LAC, pregnancy was sustained to the stage of viability.
Conclusion(S):
In patients with cervical incompetence, LAC is a very effective intervention to sustain pregnancy to the stage of viability. If placed during the preconceptional period, it does not delay achieving pregnancy and does not have a negative impact on the chances of conception. This may be reassuring to women undergoing this procedure before they achieve a pregnancy.
