Influence of Uterine Cavity Breach in Laparoscopic Myomectomy on the Risk of Obstetric Complications.

OBJECTIVES

Prepregnancy myomectomy is effective for the treatment of infertility or prevention of obstetric complications and is usually performed with laparoscopy. However, pregnancies following myomectomy have risks of obstetric complications, especially in cases with uterine cavity breaches, but the evidence remains unclear. We investigated how uterine cavity breach in laparoscopic myomectomy influenced the occurrence of obstetric complications.

PATIENTS AND

METHODS

One hundred and eighty women who underwent a cesarean section from 2014 to 2020 in pregnancies following laparoscopic myomectomy were included. They were divided into two groups: 25 women in the uterine cavity breach group and 155 in the nonbreach group. Obstetric complications, including placenta accreta spectrum (PAS), uterine rupture, placental malposition, abruption placenta, preterm delivery, threatened premature labor, premature rupture of membranes, and massive intrapartum hemorrhage, were assessed.

RESULTS

Multivariate analysis revealed that the frequency of PAS in the breach group (24.0%) was statistically significantly higher than in the nonbreach group (5.2%, P < 0.05).

CONCLUSION

This study demonstrated that women who experienced uterine cavity breach in laparoscopic myomectomy had an increased risk of PAS in subsequent pregnancies.
