Is hysteroscopic metroplasty using the incision method for septate uterus a risk factor for adverse obstetric outcomes?

AIM: This study aimed to assess whether hysteroscopic metroplasty using the incision method for septate uterus is a risk factor for adverse obstetric outcomes during pregnancy or delivery.

METHODS

This retrospective, single-center cohort study of obstetric complications included 41 patients with recurrent pregnancy loss or unexplained infertility who underwent hysteroscopic metroplasty using the incision method for septate uterus. As controls, we recruited 1139 women who delivered at our hospital during the same period. The primary outcomes were mean weeks of delivery, mean birthweight, rate of cesarean section, rate of breech presentation, rate of post-partum hemorrhage, rate of preterm delivery, rate of placental abruption, rate of placenta previa, rate of placenta accreta and uterine rupture during pregnancy and delivery.

RESULTS

The two groups did not differ in terms of age, mean weeks of delivery, mean birthweight, rate of post-partum hemorrhage, rate of preterm delivery, rate of placental abruption, rate of placenta previa or rate of placenta accreta. The rates of cesarean section and breech presentation were significantly higher in the study group than in the control group (56.1 vs 27.7%; P = 0.0002 and 19.5 vs 6.8%; P = 0.007, respectively). There were no cases of uterine rupture during pregnancy or delivery following hysteroscopic metroplasty.

CONCLUSION

Hysteroscopic metroplasty using the incision method for septate uterus is not a risk factor for adverse obstetric outcomes. No severe complications, such as placenta abruption, placenta previa, placenta accreta, uterine rupture or heavy hemorrhage, were observed in the postoperative live birth group.
