[Validation of the cervical length education and review program in a population of French residents in obstetrics and gynecology]. / Intérêt d'une formation théorique des internes de gynécologie obstétrique à la mesure échographique du col utérin.

OBJECTIVES: Evaluate an educational program based on "CLEAR" (Cervical Length Education and Review) in the teaching of measuring sonographic cervical length to residents in gynecology and obstetrics. METHODS: This is a prospective cohort study in a tertiary care center between May and November 2017. The residents were asked to collect 5 cervical length images from patients suspected with threatened preterm labor. A theoretical session on cervix measurement image criteria based on "CLEAR" program was taught to all residents. Then, they had to collect 5 new cervical length images. All the images were reviewed by two experienced reviewers, blinded to the resident and whether the image was obtained before or after the theoretical session and based on 8 criteria. RESULTS: Ten residents participated to the study. The mean total score CLEAR was significantly higher post-intervention: 6.6±0.9 vs. 4.3±2.1, positive difference of 2.3±2.3 (P<0.001). Improvement was most significant with the junior residents: 3.6 pre vs. 6.5 post-intervention. CONCLUSION: Educational program based on CLEAR criteria allowed to improve the competence of residents in measuring sonographic cervical length, although this can also be correlated with the progression of residents during the semester. It could be implemented systematically with the aim of CLEAR certification to standardize the teaching of residents in gynecology and obstetrics.

Hysteroscopic enlargement metroplasty for T-shaped uterus: 24 years' experience at the Strasbourg Medico-Surgical and Obstetrical Centre (CMCO).

STUDY QUESTION: What is the impact of hysteroscopic enlargement metroplasty for T-shaped uterus on the live birth rate? SUMMARY ANSWER: Performing enlargement metroplasty appears to improve the obstetrical prognosis and fertility in patients with a T-shaped uterus. WHAT IS KNOWN ALREADY: T-shaped uterus is linked to an excess of myometrium in the uterine walls giving rise to a subcornual constriction ring which causes dysmorphism and hypoplasia of the uterine cavity. It is commonly associated with infertility or a sequence of repeated miscarriages. STUDY DESIGN: Single-centre observational cohort study in 112 patients who underwent enlargement metroplasty for T-shaped uterus between 1992 and 2016 in a Strasbourg university hospital centre. MAIN RESULTS: The mean age of patients was 33.2; they had been attempting to conceive on average for 56 months for subfertile patients and 42.2 months for infertile patients. Prior to surgery, patients had succeeded in becoming pregnant 161 times, i.e. a mean gravidity of 1.4 pregnancies. For subfertile patients the mean gravidity was 2.67. Mean parity was 0.04. In the overall population, one hundred pregnancies occurred following enlargement metroplasty. The live birth rate increased in a statistically significant manner following enlargement metroplasty: 4 (2.5%) vs. 60 (60%), p < 0.05. In parallel, the miscarriage rate was statistically reduced: 126 (78.3%) vs. 22 (22%), pnull< .05. Intraoperative complications were 1 case of cervical laceration (0.9%) and 1 case of false passage (0.9%). Subsequent pregnancies remained at risk of miscarriage (22%) and premature delivery (20%) but not extra uterine gestation. Delivery took place by Caesarean section in 61% of cases. In the subgroup of infertile patients, the live birth rate was also markedly increased and 49% of pregnancies which occurred were spontaneous. LIMITATIONS: This study was descriptive and retrospective. WIDER IMPLICATIONS: These results are consistent with those in the literature. Hysteroscopic enlargement metroplasty is now a well-established technique with few complications but which should nevertheless be reserved for symptomatic patients.

[Outcome of in utero transfusion in case of fœtomaternal red blood cell incompatibility]. / Devenir obstétrical après transfusion in utero pour allo-immunisation fœto-maternelle.

OBJECTIVE: Erythrocyte allo-immunization's rate has decreased but without adapted treatment the prognosis is still poor. The aim of our study was to evaluate the fetal prognosis, the complication's rate and the risk factors of complications of the intrauterine transfusion. METHODS: Retrospective study about 37 fetus and 86 intrauterine transfusions between 2001 and 2017. Our main criterion in judging was the occurrence of procedure related complications: premature membrane rupture or premature delivery within seven days from the procedure, chorioamnionitis, abnormal fetal heart rate indicating an emergency ceasarean section within the 24hours from the procedure, in utero death or neonatal death related to the procedure. RESULTS: The survival rate was about 88.9% with a severe complication's rate of 5.8% per intrauterine transfusion and 13.5% per pregnancy. Intrauterine transfusions before 18 weeks of pregnancies was a complication risk factor: 50% of complications before 18 weeks vs. 1.3%, P=0.8×10-3. On the contrary, hydrops did not seem to be a complication risk factor (16.7% of complication with hydrops vs. 3.9%, P=0.27). The localisation of the needle insertion, intra-abdominal or placental insertion, had no effect on the fetal prognosis. CONCLUSION: Intrauterine transfusion complications are rare and it enhances the fetal prognosis. However, an early procedure is related to a higher rate of complications.
