Abstract

Reproductive performance of women with müllerian anomalies, Current opinion in obstetrics & gynecology, NCBI PubMed PMID: 17495638, 2007 Jun.

PURPOSE OF REVIEW
This review discusses current diagnostic techniques for müllerian anomalies, reproductive outcome data, and management options in reproductive-age women.

RECENT FINDINGS
Multiple retrospective studies have investigated reproductive outcomes with müllerian anomalies, but few current prospective studies exist. Uterine anomalies are associated with normal and adverse reproductive outcomes such as recurrent pregnancy loss and preterm delivery, but not infertility. Furthermore, unicornuate, didelphic, bicornuate, septate, arcuate, and diethylstilbestrol-exposed uteri have their own reproductive implications and associated abnormalities. Common presentations of müllerian anomalies and current diagnostic techniques are reviewed. Surgical intervention for müllerian anomalies is indicated in women with pelvic pain, endometriosis, obstructive anomalies, recurrent pregnancy loss, and preterm delivery. Although surgery for most uterine anomalies is a major intervention, the uterine septum is preferentially managed with a hysteroscopic procedure. Several recent studies and review articles discuss management of the septate uterus in asymptomatic women, infertile women, and women with a history of poor reproductive outcomes. Current assessment of reproductive outcomes with uterine anomalies and management techniques is warranted.

SUMMARY
Müllerian anomalies, especially uterine anomalies, are associated with both normal and adverse reproductive outcomes, and management in infertile women remains controversial.

Hysteroscopic metroplasty: term delivery rate after T-shaped uterus surgery

Term delivery rate after hysteroscopic metroplasty in patients with recurrent spontaneous abortion and T-shaped.

Abstract

Term delivery rate after hysteroscopic metroplasty in patients with recurrent spontaneous abortion and T-shaped, arcuate and septate uterus, Gynecologic and obstetric investigation, NCBI PubMed PMID: 21150155, 2011 Dec.

BACKGROUND
To evaluate the improvement of the term delivery rate after hysteroscopic metroplasty surgery in various uterine malformations.

METHODS
170 patients were eligible for the present retrospective case series study. Data were weighted for the number of pregnancies observed (n = 218) after surgical intervention, stratified to the number of previous abortions (at least 2) and type of malformation.

RESULTS
Before surgery, the overall term delivery rate was 5.5%. After surgery, the overall term delivery rate was 59% (absolute benefit increase, ABI, was 54.5) and correlated with the number of previous abortions (69.7% ABI = 64.2, 56.5% ABI = 51 and 26.3% ABI = 20.8 for 2, 3-4 and >4 abortions, respectively; p = 0.0008, log-rank test). Data stratified according to uterine malformations yielded the following term delivery rate: 66.7% for T-shaped uterus, 62.8% for septum/partial septum and 55.6% for arcuate uterus (NS, log-rank test). The number of previous abortions and maternal age also affected the term delivery rate. Their effect upon the term delivery rate, expressed as an odds ratio, was 1.73 (95% CI: 1.20-2.49) and 1.11 (95% CI: 1.05-1.18), respectively.

CONCLUSION
The term delivery rate was about 10-fold higher after surgery. T-shaped uterus surgery yielded the best term delivery rate.

Surgical correction of a T-shaped uterus and DES Daughters pregnancy outcome

Reconstruction in 3D-US of T-shaped uterus. Hysteroscopic metroplasty improves the live birth rate for women with a T-shaped uterus and a history of primary infertility, recurrent abortion or preterm delivery, although it is not a treatment of infertility.

Abstract

Surgical approach to and reproductive outcome after surgical correction of a T-shaped uterus, Human reproduction (Oxford, England), NCBI PubMed PMID: 21398337, 2011 Jul.
Full text: Human Reproduction, Vol.0, No.0 pp. 1–5, 2011, doi: 10.1093/humrep/der056, March 11, 2011.

BACKGROUND
The aim of this study was to describe the surgical approach to, and evaluate the reproductive outcome of, a T-shaped uterus.

METHODS
The study included 97 women who were eligible for hysteroscopic surgery, by either monopolar or bipolar electrosurgical instruments. All had diagnostic hysteroscopy 2 months afterwards to assess the success of the procedure and determine whether any synechiae were present.

RESULTS
Forty-eight women (49.5%) became pregnant after metroplasty. The overall live birth rate per pregnancy before surgery was 0%; for these patients, it increased to 73%, and their miscarriage rate fell from 78 to 27% (P < 0.05). For all 57 pregnancies in 48 women, the ectopic pregnancy rate was 9% (n = 5), the miscarriage rate 28% (n = 16), the preterm delivery rate 14% (n = 8), the term delivery rate 49% (n = 28) and the live birth rate was 63% (n = 36).

CONCLUSIONS
Hysteroscopic metroplasty improves the live birth rate for women with a T-shaped uterus and a history of primary infertility, recurrent abortion or preterm delivery, although it is not a treatment of infertility.

Discussion

A T-shaped uterus can be a primary or congenital malformation (related to DES exposure or other causes) or can be acquired due to marginal adhesions with a T-shaped appearance. The description of the surgical technique and the results of this series are important regardless of the cause of the anomaly.

Two-third of our cases had history of DES exposure, and the results of this series are encouraging for all malformations requiring modification of the cavity volume. The question of systematic cervical cerclage during pregnancy after metroplasty remains open.

Beneficial effect of hysteroscopic metroplasty on the reproductive outcome in a T-shaped uterus

Hysterosonography of T-shaped uterus. DES-exposed women with a T-shaped uterus who want to improve their reproductive function should be encouraged to undergo hysteroscopic metroplasty.

Abstract

Beneficial effect of hysteroscopic metroplasty on the reproductive outcome in a ‘T-shaped’ uterus, Gynecologic and obstetric investigation, NCBI PubMed PMID: 8821883, 1996.

Eight women (aged 27-43) with reproductive dysfunction who were diagnosed by hysterosalpingogram and hysteroscopy as having a ‘T-shaped‘ uterus were operated on using fiberoptic hysteroscopic guidance; the uterine side walls were incised until a normal uterine cavity was achieved.

The women’s gynecologic and obstetric records were compared before and after the operation.

  • In all the 8 women the operation was without complications and resulted in a satisfactory uterine cavity.
  • Before the operative procedure, the women had had 10 spontaneous abortions and 1 ectopic pregnancy.
  • The postoperative performance available for 7 of the 8 women showed 4 term pregnancies in 3 women, 1 ectopic pregnancy, and no abortions.

Our study suggests that hysteroscopic metroplasty in women with a T-shaped uterus improves the reproductive outcome, mainly in women with repeated abortions. We conclude that women with a T-shaped uterus who want to improve their reproductive function should be encouraged to undergo hysteroscopic metroplasty.

Abstract

Hysteroscopic metroplasty for uterine enlargement: a treatment for diethylbestrol-exposed and hypoplastic uteri, Journal de gynécologie, obstétrique et biologie de la reproduction, NCBI PubMed PMID: 8901300, 1996. Full text: Hysteroscopic metroplasty in diethylbestrol-exposed and hypoplastic uterus: a report on 24 cases , Human reproduction (1998) 13 (10): 2751-2755, oxfordjournals, 1996.

OBJECTIVE
To determine the feasibility of correcting the uterine deformity in the diethylbestrol-exposed uterus and hypoplastic uterus.

DESIGN
Hysteroscopic metroplasty. Patients served as their own controls.

PATIENTS
Five patients referred for primary sterility (2 cases) or primo-secondary infertility with recurrent pregnancy loss or ectopic pregnancy (3 cases). Three of them had been exposed in utero to diethylbestrol. All of them have a hypoplastic uterus or uterine deformities as seen by hysterosalpingogram.

OUTCOME MEASURES
Postoperative hysterosalpingogram aspect. Ability to conceive and carry pregnancy to livebirth.

RESULTS
All the postoperative hysterosalpingograms appeared more normal than the preoperatively. Three patients have conceived since surgery.

CONCLUSION
Hysteroscopic metroplasty is feasible. It gives good anatomic results. This technique could be used in the patients with diethylbestrol-exposed or hypoplastic uteri, with severe infertility, recurrent pregnancy loss or implantations failures in a IVF program.
