[Surgical hysteroscopy in the treatment of septate uterus: systemic treatment or selective indications].

OBJECTIVES: A retrospective study to evaluate the fertility rate after endoscopic hysteroplasty in the case of a septate uterus. METHOD: From 1st January 1988-31st December 1996, 93 patients showing a septate uterus were treated by endoscopic hysteroplasty. The hospitalisation is short: one day surgery or out office. A control of uterine cavity by hysteroscopy did next to two months. RESULTS: Patients were evaluated after a period in excess of 6 months (6 months-8 years). 63 pregnancies were achieved amongst the 84 patients to be reviewed (75%). The fertility rate achieved is higher amongst infertile patients (80.3%) compared with that of sterile patients (64%). CONCLUSION: In the presence of septate uterus the endoscopic hysteroplasty is an efficient treatment in the case of secondary infertility and of unexplained sterility.

[Birth after two cesarean sections: the role of trial of labor].

OBJECTIVE: To study the management of labor following two cesarean sections, we evaluated maternal and neonatal morbidity subsequent to this attitude. PATIENTS AND METHODS: A retrospective study was conducted over a 6-year period (1-1-1990 to 31-12-1995) in 184 women presenting two uterine scars. Trial of labor was allowed in 96 cases with cephalic presentation and a normal pelvis. RESULTS: The rate of vaginal birth was 65%. Three patients presented a uterine scar dehiscence and in one of them hemostasis hysterectomy for uterine atony was performed. Neonatal outcome was good in all cases. CONCLUSION: Trial of labor after two cesarean sections is possible in the majority of cases. Rate of vaginal birth is high and maternal and fetal morbidity is low.

[Hysteroscopic myomectomy. Functional results with an average follow-up of 6 years].

OBJECTIVE: In 1995, we presented our experience in hysteroscopic resection of hemorrhagic submucous fibroids in 196 patients. The objective of the present work was to analyze functional outcome three years later. PATIENTS: One hundred ninety-six patients with abnormal uterine bleeding were treated between 1987 and 1993. Equipment, techniques, characteristics of the procedures and early results were detailed in the previous article. RESULTS: With a mean follow-up of 73 months (range 50,104), results were: 13.8% of the patients were lost to follow-up; 68.4% had symptomatic improvement and failure was observed in 17.8% (subsequent hysterectomy in 12.7%). Forty-nine patients had repeat resection in this series; 61 became menopausal after surgery, and 21 were taking hormone replacement therapy with good results. CONCLUSION: Developed as an alternative to hysterectomy, operative hysteroscopy has proven to be a safe and effective procedure. This treatment modality appears to give satisfactory long-term results, with a low rate of complications.

Quantitative analysis of leukocyte membrane antigen expression on human fetal and cord blood: normal values and changes during development.

We studied the antibody binding capacity (ABC) of various cell-surface antigens in normal human fetuses and term neonates on lymphocyte, monocyte, and polymorphonuclear (PMN) cells by quantitative flow cytometry also designated by quantimetry. Analysis of changes of expression level on these leukocytes during the developmental process was also investigated. The results indicated that the ABC values of most studied markers change during the maturational process. The ABC of lymphocyte-associated antigens studied such as CD5 and CD7 showed only a decrease from fetus to adult, whereas according to the type of molecule on monocyte and PMN there was either an increase or a decrease of ABC values dependent on the stage of the developmental process, from fetus to neonate or from neonate to adult. However, the ABC values of leukocyte membrane antigens such as CD16, CD46, and CD55 on all leukocytes and CD11b, CD11c, and CD35 on myeloid cells did not change. Their expression level was already mature in fetuses compared with adult cells. In addition, in this quantimetric approach, the analysis of the results for CD11a and CD8 suggested that the changes of CD11a expression level on lymphocyte subsets can depend on one mechanism, whereas there are probably at least two for CD8. Furthermore, the expression patterns of CD5, CD7, and CD11a change during maturation. We concluded that, even if the neonate response pattern to immunological challenge differs from an adult and this is based primarily on the relative numbers and functional activity of lymphocyte T subsets (especially TH1/TH2) and their cytokine profiles, these quantitative and qualitative phenotypical differences might also contribute to explain the functional peculiarities of leukocyte fetal and cord blood cells. All these findings support the notion of immaturity and maturity of ABC expression.

Endoscopic surgery. The end of classic surgery?

Gynecological endoscopy is now a well-established procedure and it has been proved that the laparoscopic surgical technique can be used in the management of most gynecological disorders thus replacing conventional laparotomic procedures. The latest indications apply to such functional pathologic conditions as urinary incontinence and genital prolapse, and oncology (radical hysterectomy, lymphadenectomy). Hysteroscopy has afforded an easier surgical approach to certain pathologies such as septate uterus and endometrial ablation. Indications of conventional surgery are getting fewer. Yet conventional surgery should be part of the training of the gynecologist surgeon as the laparotomic approach is still the only solution in the most difficult cases.

Increased nuchal translucency thickness at 10-14 weeks of gestation as a predictor of severe twin-to-twin transfusion syndrome.

The study examines a possible association between increased nuchal translucency thickness at 10-14 weeks of gestation in monochorionic twin pregnancies and the subsequent development of severe twin-to-twin transfusion syndrome (TTS). In 132 monochorionic twin pregnancies, including 16 that developed severe TTS at 15-22 weeks of gestation and 116 that did not develop TTS, crown-rump length, nuchal translucency thickness and fetal heart rate were measured at 10-14 weeks. In those that developed severe TTS, the prevalence of nuchal translucency thickness above the 95th centile of the normal range and the intertwin difference in nuchal translucency thickness and fetal heart rate were significantly higher than in the non-TTS group; there were no significant differences between the groups in the inter-twin difference in crown-rump length. For fetal nuchal translucency above the 95th centile, the positive and negative predictive values for the development of TTS were 38% and 91%, respectively; the likelihood ratios of nuchal translucency above or below the 95th centile for the development of severe TTS were 4.4 (1.8-9.7) and 0.7 (0.4-0.9), respectively. These findings demonstrate that the underlying hemodynamic changes associated with TTS may manifest as increased fetal nuchal translucency thickness at 10-14 weeks of gestation.

Human thymic B cells largely overexpress the VH4 Ig gene family. A possible role in the control of tolerance in situ?

Human thymus contains a small population of B cells, a fraction of which expresses CD2 and/or CD5, as revealed by FACS analysis. Human thymic B cells enriched on CD19 panning revealed a constant co-expression of CD19 and Ig light chains. In the absence of detectable B precursors, these cells had reached at least the stage of IgM+ immature B lymphocytes. Analysis of Ig transcripts by PCR amplification first revealed a strong bias in favor of the VH4 and sequencing of 45 VH4-D-J cDNA clones isolated from two thymuses indicated that this thymic repertoire significantly differed from that of peripheral blood lymphocytes. Most genes of the VH4 family were used with various D-J combinations and a relatively high frequency of somatic mutations. This repertoire thus appears clearly selected in the thymus. This is of particular interest since the VH4 gene family is frequently encountered in autoimmunity a situation in which the number of thymic B cells is largely increased. They could play a major role in the control of tolerance in situ.

Effects of embryo reduction from trichorionic triplets to twins.

Sixty-six trichorionic triplet pregnancies reduced to twins were compared with 47 triplet pregnancies that were not reduced. The miscarriage rate was higher (7.6% compared with 2.6%) but the number delivering between 24 and 32 weeks was lower (8.2% compared with 24.0%). Since severe preterm delivery is associated with risks of neonatal death and severe handicap, embryo reduction of triplets to twins may not improve the chance of survival but may reduce the rate of handicap.

Dichorionic twins discordant for intrauterine growth retardation.

A policy of expectant management until 32 weeks of gestation in 29 dichorionic pregnancies discordant for growth retardation resulted in an overall mortality of 24% (95% CI 13.9-37.2%) and a handicap of 2.2% (95% CI 0-12.0%). None of the normally grown co-twins died or was handicapped as a result of iatrogenic prematurity.

[Endometrial resection in the management of menometrorrhagia refractory to medical treatment].

The authors report the results of 197 endometrectomies and analyse the indications, complications and long-term results. A retrospective analysis was performed at La Conception Hospital. Department of Gynaecology-Obstetrics, Prof Blanc, Marseille, between June 1988 and June 1994. The mean follow up was 53 months. 197 endometrectomies were performed in 186 women during this period. The indication was menometrorrhagia failing to respond to medical therapy. We considered patients to be cured when they no longer suffered from menorrhagia or metrorrhagia and when hormone replacement therapy could be started or continued. The success rate with a follow-up of 7 years was 70%. The failure rate was correlated with the woman's age, hysterometry data and histological results. The complication rate was 2.5%. Endometrectomy appears to be a safe and successful technique for the treatment of menometrorrhagia.

[Role of endo-uterine resection using hysteroscopy in the treatment of sub-mucous hemorrhagic fibroma in the peri-menopausal period].

OBJECTIVES: To study retrospectively the long-term outcome after hysteroscopic treatment for intra-uterine fibromas. METHODS: From October 1987 to January 1993, endo-uterine glycocol resection was performed in 196 patients with intra-uterine fibromas. The operation had to be repeated in 39 patients due to incomplete resection or recurrent symptomatology. Patients presented with menometrorrhage. RESULTS: Intra-operative complications were rare, mainly uterine perforations (7 cases) or metabolic syndromes due to reabsorption of glycine (5 cases). Mean follow-up was 2.5 years. In all 196 women consulted for bleeding, good results were achieved in 81.1%. CONCLUSION: Endo-uterine resection is a sure, effective and long-lasting treatment for intra-uterine fibromas.

[Richter's spinofixation in vaginal prolapse].

The transvaginal sacrospinous fixation, called Richter operation was initially aimed to cure vaginal vault prolapse after hysterectomy. The results are as good as those of the abdominal promontory fixation with the well known advantages of the vaginal route. Indications way be extended to V3 U3 R3 prolapse and cure of elytrocele with good results in our practice. In few cases remnant cystocele may be a trouble some problem.

Hysteroscopic management of uterine synechiae: a series of 102 observations.

This retrospective study concerns 102 cases of intra-uterine adhesions treated by exclusive hysteroscopic approach. Fifty-two patients (51%) presented with reproductive problems, 44 patients (43%) with menstrual problems and 6 were asymptomatic. Seventy-eight patients (76.5%) had an antecedent endometrial trauma on a gravid uterus. One hundred and forty-eight operative hysteroscopies were performed to treat 102 patients; 70 patients were treated in one endoscopic session (68.6%), 23 in two sessions (22.6%), 4 in three sessions (3.9%) and 5 in four sessions (4.9%). We report no infectious, hemorragic or metabolic complication but 6 perforations (5.8%). The mean follow-up is 24.4 months (from 6 to 46 months). Ten patients did not keep contact during follow-up. A good anatomical result was obtained in 88 patients (86.2%) after one or two hysteroscopic sessions. A good result on menstrual problems was obtained in 75% of the cases, especially in amenorrhea (90.5% success rate). The reproductive outcome is more disappointing. We obtained 34 pregnancies in 28 patients (10 abortions, 24 live born children). Twenty-two patients achieved no pregnancy (44%), but 13 of these patients presented with additional infertility factors.

Hysteroscopic management of menstrual disorders: a review of 395 patients.

OBJECTIVE: To evaluate the long-term effectiveness of transcervical resections in menstrual disorders. DESIGN: Retrospective consecutive patient follow-up. PATIENTS: From 1987 to 1993, 395 patients with menstrual disorders (menorrhagia and/or metrorrhagia) were treated with operative hysteroscopy in our department. Resection of endometrial polyps was performed in 65 cases, resection of submucous fibroids in 196, and endometrial ablation in 134. Fourty-one patients had a repeat procedure. RESULTS: Our mean follow-up period was 2.7 years. Thirteen complications were noted (3%), two of which were serious (one hemoperitoneum after uterine perforation, one severe symptomatic hyponatremia). Twenty-eight patients did not remain in contact after hospitalization (7.1%). Menstrual disorders were controlled in 297 patients (75.2%). Failure was noted in 70 patients (17.7%), including hysterectomy in 50 patients and persistent bleeding in 20. CONCLUSION: Hysteroscopic surgery is a satisfying technique for women with abnormal uterine bleeding who want a conservation of the uterus. Better results are noted with resections of polyps and fibroids than with endometrial ablations.
