Abstract:

Objective: To investigate the reproductive prognosis of patients with Herlyn-Werner-Wunderlich syndrome (HWWS) after minimally invasive surgery and analyze the pregnancy outcomes and influencing factors. Methods: A retrospective analysis was conducted on the clinical data of 25 HWWS patients with fertility requirements who underwent minimally invasive surgery at the Hysteroscopy Diagnosis and Treatment Center of Fuxing Hospital Affiliated to Capital Medical University from April 2008 to December 2023. All patients underwent hysteroscopy or combined hysteroscopy and laparoscopy, and their pregnancy outcomes were followed up. Results: The postoperative pregnancy rate(80% vs. 8%) and live birth rate (69.2% vs. 0%) of the 25 patients were significantly improved compared with those before surgery, and the differences were statistical significant(P<0.05). The incidence of preterm birth rate was 23.1%(6/26). 20 patients achieved successful pregnancy after surgery, among which 17 were spontaneous pregnancies and 3 patients were conceived through in vitro fertilization-embryo transfer. Adverse pregnancy outcomes included preterm birth, miscarriage, and induced abortion due to fetal malformation. There were differences in pregnancy outcomes among patients with uterus didelphys, septate uterus and bicornuate uterus. In patients with uterus didelphys, pregnancy mostly occurred on the side of the oblique vaginal septum, while patients with septate uterus had a higher postoperative fertility rate. All parturient patients underwent cesarean section. Conclusions: The pregnancy and live birth rates of HWWS patients are significantly improved after minimally invasive surgery, but adverse pregnancy outcomes such as preterm birth and miscarriage need attention. Factors such as the type of uterine malformation, pregnancy location, and surgical approach affect pregnancy outcomes. Close postoperative monitoring and management are crucial for improving reproductive prognosis.
