Fifteen women with diminished fertility as a result of congenital uterine anomalies were treated by cervical suture (cerclage) in the 11th-12th week of pregnancy without surgical correction of the uterine anomaly. None of these women had either clinical or radiological evidence of cervical incompetence. As a result of the treatment, 13 of the women delivered live full-term mature infants. None of the women aborted, only two women delivered prematurely, and both infants were alive and well. Comparison of these good results to the very poor outcome of previous pregnancies in these women points to a distinct advantage to be gained by cervical suture. As a result of this experience, we recommend cervical suture in cases of diminished fertility as a result of congenital uterine anomaly. We recommend that the suture be performed before considering surgical repair of the anomaly and irrespective of lack of evidence of cervical incompetence. Only in cases where cervical suture is unsuccessful, would we recommend surgical correction according to the accepted techniques.

A total of 182 women with uterine anomalies were observed over a period of 18 years. In all, 126 women had 265 pregnancies, fetal survival rate was 66%, perinatal mortality 8% and premature labors occurred in 23%. When the uterine anomalies were grouped according to degree of failure of normal and uterine development, the complete septate uteri had the best fetal survival rate (86%), complete bicornuate uteri (50%) and unicornuate (40%) poorest. Cervical cerclage was applied most in the partial bicornuate uteri (17%), where fetal survival in operated cases was: before operation, 53% and after, 100%. The frequency of breech presentation was 40-50% in all groups except complete septate uteri (25%) and complete bicornuate (0%). The highest cesarean section rate (82%) was in deliveries of patients with uterus didelphys. The frequency of cesarean section among total deliveries was 53%. Metroplasty was carried out on 19 patients. The obstetric outcome improved from 10% successful pregnancies before surgery to 88% postoperatively.
Patients with two or more previous spontaneous second trimester abortions and vaginal cytology indicating a poor progestational response in current pregnancies were selected for treatment with Provera (medroxyprogesterone acetate) and/or Delalutin (17 alpha-hydroxyprogesterone caproate). Serum was examined serially for progesterone (P) and estradiol (E) by radioimmunoassay. Serum from 174 untreated patients with no known complications ranging from 6--40 weeks gestation provided normal distribution data. Of 14 progestagen-treated patients, four aborted during the second trimester. These all had chronically low (greater than 50% of observations were less than 1 standard deviation of the normal population) or falling P/E ratios. The rest delivered normal full-term infants although five of the 10 had chronically low P, seven had chronically low P/E ratios, and in one other P/E was falling. Chronically high E contributed to the low P/E ratio in three cases. Thus, these selected cases with poor obstetrical histories demonstrated steroid patterns outside the +/- 1 standard deviation range, although the steroid levels were still within the normal range. Serum progesterone and estradiol analysis may eventually be useful in identifying patients who will best respond to progestagen treatment.

Endometriosis is a chronic gynaecological condition affecting reproductive-aged women. It has been associated with infertility and potential risks for adverse pregnancy outcomes, although population-level evidence remains limited. This retrospective cohort study, including 147,950 pregnant women aged 20-45 years, used nationwide population-based data to compare the outcomes between women with (n = 11,400) and without (n = 136,550) endometriosis between 2000 and 2021. Baseline characteristics, comorbidities and pregnancy outcomes were compared between the groups. Multivariable regression analyses were performed to calculate adjusted relative risks (aRR) and 95 % confidence intervals (CI) for various pregnancy outcomes, and subgroup analyses were conducted by maternal age and infertility status. Among 147,950 pregnancies, women with endometriosis [mean ± standard deviation (SD) age 32.38 ± 4.51 years] had higher socio-economic status, more comorbidities, and more surgical history compared with women without endometriosis (mean ± SD age 30.06 ± 4.96 years). Women with endometriosis had increased risk of miscarriage (aRR 1.13, 95 % CI 1.03-1.24), preterm birth (aRR 1.31, 95 % CI 1.26-1.37), premature rupture of membranes (aRR 1.11, 95 % CI 1.06-1.16), placenta previa (aRR 1.63, 95 % CI 1.45-1.84), urinary tract infection (aRR 1.44, 95 % CI 1.31-1.59), and caesarean section (aRR 1.13, 95 % CI 1.11-1.16). Subgroup analysis revealed that risk of miscarriage was only higher in women aged 35-45 years and women without infertility. Risks of preterm birth, placenta previa and caesarean section were elevated across all subgroups, suggesting that endometriosis contributes independently to adverse pregnancy outcomes. Endometriosis is an independent risk factor for several pregnancy complications, supporting the need for tailored prenatal care and closer monitoring of affected women to improve maternal outcomes.

After preterm premature rupture of membranes at <24 weeks' gestation, pregnant women may choose continuation (expectant management) or termination of pregnancy, via either dilation and evacuation or labor induction. Neonatal outcomes after expectant management are well described. In contrast, limited research addresses maternal outcomes associated with expectant management compared to termination of pregnancy. This study aimed to compare maternal morbidity after preterm premature rupture of membranes at <24 weeks' gestation in women who choose either expectant management or termination of pregnancy. This retrospective cohort study included women with preterm premature rupture of membranes between 14 0/7 and 23 6/7 weeks' gestation with singleton or twin pregnancies at 3 institutions from 2011 to 2018. We excluded pregnancies complicated by fetal anomalies, rupture of membranes immediately after obstetrical procedures (chorionic villus sampling, amniocentesis, cerclage placement, fetal reduction), spontaneous delivery <24 hours after membrane rupture, and contraindications to expectant management. Our primary outcome was the difference in composite maternal morbidity between women choosing expectant management and women choosing termination of pregnancy. We defined composite maternal morbidity as at least 1 of the following: chorioamnionitis, endometritis, sepsis, unplanned operative procedure after delivery (dilation and curettage, laparoscopy, or laparotomy), injury requiring repair, unplanned hysterectomy, unplanned hysterotomy (excluding cesarean delivery), uterine rupture, hemorrhage of >1000 mL, transfusion, admission to the maternal intensive care unit, acute renal insufficiency, venous thromboembolism, pulmonary embolism, and readmission to the hospital within 6 weeks. We compared the demographic and antenatal characteristics of women choosing expectant management with that of women choosing termination of pregnancy and used logistic regression to quantify the association between initial management decision and composite maternal morbidity. We identified 350 women with pregnancies complicated by preterm premature rupture of membranes at <24 weeks' gestation, and 208 women were eligible for the study. Of the 208 women, 108 (51.9%) chose expectant management as initial management, and 100 (48.1%) chose termination of pregnancy as initial management. Among women selecting termination of pregnancy, 67.0% underwent labor induction, and 33.0% underwent dilation and evacuation. Compared to women who chose termination of pregnancy, women who chose expectant management had 4.1 times the odds of developing chorioamnionitis (38.0% vs 13.0%; 95% confidence interval, 2.03-8.26) and 2.44 times the odds of postpartum hemorrhage (23.1% vs 11.0%; 95% confidence interval, 1.13-5.26). Admissions to the intensive care unit and unplanned hysterectomy only occurred after expectant management (2.8% vs 0.0% and 0.9% vs 0.0%). Of women who chose expectant management, 36.2% delivered via cesarean delivery with 56.4% non-low transverse uterine incisions. Composite maternal morbidity rates were 60.2% in the expectant management group and 33.0% in the termination of pregnancy group. After adjusting for gestational age at rupture, site, race and ethnicity, gestational age at entry to prenatal care, preterm premature rupture of membranes in a previous pregnancy, twin pregnancy, smoking, cerclage, and cervical examination at the time of presentation, expectant management was associated with 3.47 times the odds of composite maternal morbidity (95% confidence interval, 1.52-7.93), corresponding to an adjusted relative risk of 1.91 (95% confidence interval, 1.35-2.73). Among women who chose expectant management, 15.7% avoided morbidity and had a neonate who survived to discharge. Expectant management for preterm premature rupture of membranes at <24 weeks' gestation was associated with a significantly increased risk of maternal morbidity when compared to termination of pregnancy.
