L’élévation du taux de césariennes : un progrès nécessaire de l’obstétrique moderne

During the last 10 Years, the cesarean section (CS) rate was increased despite of the recommendations of the World Health Organization to keep it below 10-15%. The purpose of this review of the literature was to demonstrate how the concept of CS rate limitation has become obsolete. The increase in the CS rate is mainly justified by the decrease in maternal mortality and morbidity following elective CS: surgery-related risks have decreased and the confusion that was made between the risks of vaginal delivery and those of trial of labor has to be clarified to show that maternal mortality and morbidity are not increased by elective CS. However, instrumental delivery and CS during labor remain two situations at high risks both for the mother and her fetus. There is also an association between the increase in the CS rate and the decrease in perinatal mortality and morbidity, but this effect would only become clinically significant after a dramatic increase in the CS rate: this is the preventile principle of "marginal death". Numerous articles have been published reporting on the effects of vaginal delivery for the pelvic floor: urinary incontinence, pelvic organ prolapse, and especially fecal incontinence. All these publications concluded that CS has a protective effect. The rising duty to provide information to patients in high risk obstetrical situations such as a history of CS also contributes to the overall increase in CS rate mainly through the elective CS rate. Indeed, when faced with the alternative choices of potentially severe complications either for themselves or their child, women are likely to choose what appears to be the safest mode of delivery for their child and thus to opt for a CS. Finally, widespread delivery of information to the patients about trial of labor itself and the risks of vaginal delivery is the first step towards a "principle of preference", which consists in giving an important place to the patient's choice in the decision-making process, and thus to recognize her right to ask for an elective CS.

Vaginal evisceration long after vaginal hysterectomy

BACKGROUND

Vaginal evisceration can take place many years after vaginal surgery.

CASE

An 87-year-old woman presented with evisceration of small bowel through the vagina, 15 years after she underwent a vaginal hysterectomy. On physical examination, her vital signs were normal. Forty centimeters of small bowel was visible emerging from the vagina, appearing viable and nonedematous. Because of the high surgical risk, the bowel was replaced and the defect in the vaginal wall was repaired transvaginally.

CONCLUSION

Vaginal evisceration can be treated by a transvaginal surgical approach. Factors such as the medical condition of the patient and the viability of the herniated viscus should dictate the optimal approach in each case.

Randomized, prospective, double-blind comparison of abdominal and vaginal hysterectomy in women without uterovaginal prolapse

BACKGROUND

To determine under controlled conditions whether there are significant differences in the duration of hospitalization and recovery between abdominal and vaginal hysterectomy for indications other than uterovaginal prolapse.

METHOD

In a two-center prospective, double-blind randomized trial, 36 women with dysfunctional uterine bleeding, uterine fibroids or pelvic pain scheduled for hysterectomy were randomized to abdominal or vaginal hysterectomy. The primary outcome measure was the duration of hospital stay. Secondary outcome measures included analgesic requirements and return to normal health and function.

RESULTS

There were no significant differences in peri-operative patient or surgical characteristics. Vaginal hysterectomy was associated with a reduction in hospital stay compared to abdominal hysterectomy (median stay 3 days vs. 5 days, p = 0.01). In addition, patients undergoing vaginal hysterectomy had reduced analgesic requirements (mean 75.4 mg vs. 131.4 mg morphine equivalent, p = 0.002), shorter need for intravenous hydration (mean 25.3 h vs. 32.7 h, p = 0.05), and faster return of bowel action (median 3 days vs. 4 days, p = 0.002). They also returned to normal domestic activities (mean 4.6 weeks vs. 8.5 weeks, p = 0.01) and work (mean 7.0 weeks vs. 13.9 weeks, p = 0.005), and completed their recovery (mean 7.9 weeks vs. 16.9 weeks, p = 0.008) more quickly.

CONCLUSIONS

Vaginal hysterectomy was associated with significant benefits in terms of reduced hospital stay and improved patient recovery. Vaginal hysterectomy should be the route of choice not only for women with genital tract prolapse but also those without.

Informed consent and birth: protecting the pelvic floor and ourselves

The controversy over elective cesarean versus vaginal birth with regard to pelvic floor trauma has left many caregivers and patients confused. With the growing evidence to support the development of fecal incontinence as a result of childbirth, we believe that it is imperative to reevaluate modern obstetric practices both for the patient's benefit and for our medical-legal protection. Our attention and energy need to be focused on good informed consent regarding these risks along with improved postpartum surveillance for injury.

Perception of genital prolapse: a hospital-based study in Alexandria (Part II)

Genital prolapse is a common health problem, understanding women's perceptions and beliefs may illuminate our understanding of their health seeking behavior which form a first step in any effort to improve their health. The present study was designed to investigate the perception of genital prolapse among women attending the outpatient clinic in El-Shatby Maternity University Hospital in Alexandria. Data was collected from a sample of 291 women who had any form of genital prolapse. Women's knowledge about risk factors for genital prolapse, women's beliefs related to genital prolapse as well as their beliefs about assistance at delivery (beliefs were assessed through the Health Belief Model) were measured for women who knew that they were suffering of genital prolapse (n = 40). The results revealed that more than two thirds of cases (70.4%) had poor (36.4%) or fair knowledge (34%) and only 29.6% had satisfactory knowledge. The majority of women having positive perception to diagnosis and symptoms for genital prolapse had high perception of "susceptibility" to and "severity" of complications of genital prolapse (97.5% and 85% respectively). More than two thirds (67.5%) had high scores of "perceived benefits" of treatment and medical advice, while nearly one third (32.5%) scored moderate. The majority of women (82.5%) had either moderate scores (55%) or high scores (27.5%) of perceived barriers to compliance to medical instructions or recommended surgery. About two thirds of cases (65.6%) sought medical care later than one year of perception of symptoms. Women's knowledge and degree of genital prolapse were directly related to women's report of symptoms characteristic of prolapse, while the level of education was inversely related. Health education for women on different aspects of reproduction using appropriate materials is highly recommended.

Colposuspension success and failure: a long-term objective follow-up study

The Burch colposuspension is regarded as one of the most successful procedures for the operative treatment of genuine stress incontinence. In this study the authors have attempted to define long-term subjective and objective success rates. Of 121 patients operated on between 1985 and 1995, 83 were fully assessed: 77% (64/83) had no stress leakage, but 41% (34/83) were suffering from urge incontinence. On clinical assessment 6 cases of uterine prolapse or vault descent, 21 cystoceles (25%) and 47 rectoceles or rectoenteroceles (57%) were detected, all but 8 being asymptomatic. On ultrasound 64/83 patients (77%) had a normal result. Ten patients demonstrated bladder neck hypermobility and in 9 there was urethral funneling without hypermobility. Survival analysis showed that the likelihood of all types of failure and of abnormal ultrasound findings increased over time. It is proposed that long-term results after incontinence surgery be presented as survival analysis.

[Complications of vaginal hysterectomy on non-prolapsed uterus]

OBJECTIVE

To assess our rate of complications after vaginal hysterectomy and those described in the literature, particularly in high risk groups such as obese, nulliparous women with previous abdomino-pelvic surgery or after GnRH administration.

METHOD

We retrospectively looked for complications in 490 patients who underwent vagina l hysterectomy between 1990 and 1998: infections, hemorrhage, intraoperative complications, thrombophlebitis or pulmonary embolism, postoperative complications up to one month. The chi-squared test, t test for equality of means and Fisher's exact test were used for statistical analysis.

RESULTS

The complication rate observed in our series (20.7%) was similar to those reported in the literature. We found no difference in the obese group (n=109) the nulliparous women (n=34), after GnRH administration (n=24) or i women with previous abdomino-pelvic surgery (n=128). Heavy bleeding was not increased by morcellation.

CONCLUSION

Vaginal hysterectomy is easy and safe. The vaginal route is the best way for obese subjects and can be carried out in most cases, especially in nulliparous women or after GnRH analogs, even when morcellation is necessary, without increasing morbidity.

How to increase the proportion of hysterectomies performed vaginally

OBJECTIVES

The main purpose of our study was to identify the patient characteristics of women undergoing hysterectomy and to estimate the proportion of hysterectomies that could be done vaginally by recognized surgical techniques.

STUDY DESIGN

The records of 500 women who underwent hysterectomy were reviewed. The characteristics of patients without an absolute contraindication to vaginal hysterectomy were analyzed.

RESULTS

Overall, 96 (19.2%) of our study group underwent vaginal hysterectomy. A total of 382 (76.4%) women were judged not to have an absolute contraindication to this route. The most frequent characteristics of this group were lack of uterine prolapse (76.4%), a myomatous uterus (44.5%), and a need for oophorectomy (43.2%). We did not exclude women who did not have significant uterine prolapse or a history of pelvic surgery or pelvic tenderness and we included those requiring oophorectomy or with a uterine size up to that of 14 weeks' gestation; with these criteria more than two thirds of the entire study population could undergo vaginal surgery.

CONCLUSIONS

To maximize the proportion of hysterectomies performed vaginally, gynecologists need to be familiar with surgical techniques for dealing with nonprolapsed uteri, uterine leiomyomas, and vaginal oophorectomy.

Pregnancy and intercurrent diseases of the urogenital tract

Pregnancy, labor, delivery, and the puerperium cause many changes in the urinary and genital tracts. The management of lower urinary tract symptoms, disease, and genital prolapse during and after pregnancy is controversial. Patients treated surgically for incontinence, genital prolapse, and lower urinary tract reconstruction present a challenge to the obstetrician and other doctors caring for them during pregnancy. This article reviews the literature on the effect of pregnancy, labor, delivery, and the puerperium on lower urinary and genital tract disease. Preventive methods to reduce subsequent pelvic floor muscle damage and urinary and fecal incontinence are reviewed. The management of pregnant women with antecedent urinary and genital tract abnormalities also are summarized.

Blunt trauma of uterovaginal and vesical prolapse with associated bladder rupture

A 71-year-old woman had complete uterovaginal and vesical prolapse associated with a large decubitus ulcer on the anterior vaginal wall. She sustained blunt trauma to the perineum after a fall, which resulted in rupture of the prolapsed bladder. The management of this rare problem is discussed.
