Clinical Effectiveness of Modified Laparoscopic Fimbrioplasty for the Treatment of Minimal Endometriosis and Unexplained Infertility

Abstract EN

Objective.

To study the reproductive outcomes of modified laparoscopic fimbrioplasty (MLF), a surgical technique designed to increase the working surface area of the fimbriated end of the fallopian tube.

We postulated that an improvement in fimbrial function through MLF will improve reproductive outcomes.

Design.

Retrospective cohort study.

Setting.

Academic tertiary-care medical center.

Patients.

Women with minimal endometriosis or unexplained infertility, who underwent MLF during diagnostic laparoscopy (n=50) or diagnostic laparoscopy alone (n=87).

Intervention.

MLF involved gentle, circumferential dilatation of the fimbria and lysis of fimbrial adhesions bridging the fimbrial folds.

Main Outcome Measures.

The primary outcome was pregnancy rate and the secondary outcome was time to pregnancy.

Results.

The pregnancy rate for the MLF group was 40.0%, compared to 28.7% for the control group.

The average time to pregnancy for the MLF group was 13 weeks, compared to 18 weeks for the control group.

The pregnancy rate in the MLF group was significantly higher for patients ≤35 ys (51.5% versus 28.8%), but not for those >35 ys (17.6% versus 28.6%).

Conclusion.

MLF was associated with a significant increase in pregnancy rate for patients ≤35 ys.
