[Proposition of a simplified investigation model for adverse outcomes in obstetrics and gynaecology].
Investigation of adverse outcomes in obstetrics and gynaecology requires a systematic and systemically oriented approach. The main objective of these assessments is to decrease their incidence. Lethal complications in obstetrics and gynaecological surgery have become so rare in developed countries that we have to grapple mainly with severe morbidities. A model for such investigation is presented, based on answers to 3 questions: What? How? and Why? These questions correspond to 3 components of quality assurance: Outcome, Process, and Structure, respectively. Aspects of Reason's model of accidents are also included, in the form of "active failures" and "latent conditions." The latter are divided into basic contributory factors, 4 of which are derived from a model of human factors influencing behaviour in anaesthesia or flight-crew environments. To illustrate its basic nature, the model is applied to anonymized cases of surgical complications. Application of the model to the reactive investigation of close calls is discussed, as is application to the proactive interrogation of the care system for the presence and nature of hazards that pose threats to safety.

[Use of prosthetic materials in reconstructive pelvic floor surgery. An evidence-based analysis].
Many surgical procedures for the repair of pelvic organ prolapse are used nowadays. Reconstructive pelvic surgery continues to evolve while surgeons continue to search the definitive surgical cure and have to choose the most appropriate procedures for their patients. Concerning the vaginal approach procedures, there is an increasing interest in the use of synthetic meshes which are at present widely used for surgical repair of pelvic organ prolapse. Prosthetic repair seems to be more reliable, especially when native tissues are of poor quality. The use of synthetic meshes may also simplify surgical procedures and reduce operative duration and morbidity. Material must be inert, permanent and resistant to infection. Based on authors' and other researchers' published experimental and clinical experience, polypropylene is assumed to be the most appropriate material for the vaginal repair of pelvic organ prolapse. However, since no standardized outcome measure is available, it is difficult to compare the results of surgical procedures. Only in recent studies, the subjective cure rates (patient satisfaction and outcome) have been assessed as well as the objective cure rates determined by the investigators. The subjective cure rate is probably more influenced by the functional outcome and sexual activity than by the anatomical result. Continuous evaluation is necessary to study replacement synthetic materials which should improve the rate of prolapse recurrence and reduce the risk of complications. Randomized controlled trials are required to determine which surgical procedures and type of prosthesis are most suitable. This review evaluates the properties of prosthetic materials, their complications and the most common procedures involved in the use of meshes for pelvic reconstructive surgery.

Endometriosis and pelvic pain: epidemiological evidence of the relationship and implications.
The relationship between chronic pelvic pain symptoms and endometriosis is unclear because painful symptoms are frequent in women without this pathology, and because asymptomatic forms of endometriosis exist. Our comprehensive review attempts to clarify the links between the characteristics of lesions and the semiology of chronic pelvic pain symptoms. Based on randomized trials against placebo, endometriosis appears to be responsible for chronic pelvic pain symptoms in more than half of confirmed cases. A causal association between severe dysmenorrhoea and endometriosis is very probable. This association is independent of the macroscopic type of the lesions or their anatomical locations and may be related to recurrent cyclic micro-bleeding in the implants. Endometriosis-related adhesions may also cause severe dysmenorrhoea. There are histological and physiopathological arguments for the responsibility of deeply infiltrating endometriosis (DIE) in severe chronic pelvic pain symptoms. DIE-related pain may be in relation with compression or infiltration of nerves in the sub-peritoneal pelvic space by the implants. The painful symptoms caused by DIE present particular characteristics, being specific to involvement of precise anatomical locations (severe deep dyspareunia, painful defecation) or organs (functional urinary tract signs, bowel signs). They can thus be described as location indicating pain. A precise semiological analysis of the chronic pelvic pain symptoms characteristics is useful for the diagnosis and therapeutic management of endometriosis in a context of pain.

The sheathed flagellum of Brucella melitensis is involved in persistence in a murine model of infection.
Persistence infection is the keystone of the ruminant and human diseases called brucellosis and Malta fever, respectively, and is linked to the intracellular tropism of Brucella spp. While described as non-motile, Brucella spp. have all the genes except the chemotactic system, necessary to assemble a functional flagellum. We undertook to determine whether these genes are expressed and are playing a role in some step of the disease process. We demonstrated that in the early log phase of a growth curve in 2YT nutrient broth, Brucella melitensis expresses genes corresponding to the basal (MS ring) and the distal (hook and filament) parts of the flagellar apparatus. Under these conditions, a polar and sheathed flagellar structure is visible by transmission electron microscopy (TEM). We evaluated the effect of mutations in flagellar genes of B. melitensis encoding various parts of the structure, MS ring, P ring, motor protein, secretion apparatus, hook and filament. None of these mutants gave a discernible phenotype as compared with the wild-type strain in cellular models of infection. In contrast, all these mutants were unable to establish a chronic infection in mice infected via the intraperitoneal route, raising the question of the biological role(s) of this flagellar appendage.

Presurgical diagnosis of posterior deep infiltrating endometriosis based on a standardized questionnaire.
BACKGROUND: To derive a diagnostic model based on symptoms and history as assessed by a standardized questionnaire to predict posterior deep infiltrating endometriosis (DIE) among women with chronic pelvic pain symptoms. METHODS: 134 women scheduled for laparoscopy for chronic pelvic pain symptoms completed a standardized self-administered questionnaire, specifically designed for the study. We compared the symptoms of the women with posterior DIE diagnosed at laparoscopy with those of the women with other disorders, and used multiple logistic regression analysis to select the best combination of symptoms for predicting posterior DIE. Cross-validation was performed with the jackknife method. RESULTS: 51 women (38.1%) were diagnosed with posterior DIE and 83 with other disorders (61.9%). The following variables were independent predictors for posterior DIE: painful defecation during menses, severe dyspareunia (visual analogic scale > or =8), pain other than noncyclic, and previous surgery for endometriosis. The cross-validation procedure leads to a simplified diagnostic model that uses two independent predictors: painful defecation during menses and severe dyspareunia. The sensitivity of this model for diagnosing posterior DIE was 74.5%, its specificity was 68.7%, its positive likelihood ratio was 2.4, and its negative likelihood ratio was 0.4. It correctly classified 70.9% of our sample into a high-risk (with either severe dyspareunia or painful defecation during menses) and a low-risk (neither symptom) group. CONCLUSIONS: Standardized evaluation of painful symptoms is useful for screening women so that they may have adequate exploration and counselling before laparoscopic surgery for pelvic pain symptoms.

Accuracy of rectal endoscopic ultrasonography and magnetic resonance imaging in the diagnosis of rectal involvement for patients presenting with deeply infiltrating endometriosis.
OBJECTIVE: To compare the accuracy of rectal endoscopic ultrasonography (REU) and magnetic resonance imaging (MRI) for predicting rectal wall involvement in patients presenting histologically proven deeply infiltrating endometriosis (DIE). METHODS: This was a retrospective study of a continuous series of 81 patients presenting histologically proven DIE who underwent preoperative investigations using both REU and MRI. The sonographer and the radiologist, who were unaware of the clinical findings and patient history, but knew that DIE was suspected, were asked whether there was involvement of the digestive wall. RESULTS: Rectal DIE was confirmed histologically in 34 of the 81 (42%) patients. For the diagnosis of rectal involvement, sensitivity, specificity and positive and negative predictive value for REU were 97.1%, 89.4%, 86.8% and 97.7% and for MRI they were 76.5%, 97.9%, 96.3% and 85.2%. CONCLUSION: The sensitivity and negative predictive value of REU were higher than those of MRI suggesting that REU performs better than MRI in the diagnosis of rectal involvement for patients presenting with DIE. Prospective studies with a large number of patients are needed in order to validate these preliminary results.

[Cystocele repair by vaginal approach with a tension-free transversal polypropylene mesh. Technique and results].
OBJECTIVE: To evaluate mid term results, tolerance and efficiency of interposition of a tension-free polypropylene monofilament mesh by vaginal approach for the repair of cystoceles. PATIENTS AND METHODS: Fourty consecutive women underwent this new procedure between March 2001 and September 2002. After complete dissection of the cystocele, the polypropylene mesh (Gynemesh), Gynecare, Ethicon, Johnson & Johnson, France), proper cut-out was positioned under the bladder without any fixation. The lateral extensions of the mesh where introduced in the para-vesical spaces in contact with the arcus tendinus fascia pelvis. RESULTS: Before surgery all patients had cystocele of more or equal than grade II according to the POP-Q classification. Eight had grade II cystocele (20%) and 32 had grade III cystocele (80%). Thirty women had associated posterior or median prolapse (82.5%). Thirty women had urinary incontinence (75%). Mean age was 63.9 years (51-78). The procedure was performed without any difficulty in all cases. Duration of a cystocele cure procedure was 20 min +/- 2.2 (16-24). Mean follow-up is 16.4 months +/- 4.7 (12-24). The early complication rate was 7.5% (two vaginal erosions and one complete exposition of the mesh which requires secondary ablation). There was no mesh infection. The success rate was 95%. The satisfaction index overpasses 80% in 95% of our patients 6 months after the cystocele repair. DISCUSSION AND CONCLUSIONS: The interposition of a sub-vesical transversal tension-free polypropylene mesh by the vaginal route seems to be an excellent procedure in the definitive surgical treatment of grades II and III anterior vaginal wall prolapse. This new procedure is simple, mini-invasive, reproducible and efficient with low morbidity and good tolerance.

[Embolization of uterine fibroids and infertility: is a clinical trial conceivable?].
Uterine artery embolization is a recent technique intended for treating uterine fibroids, as an alternative to hysterectomy. The possible side effects putting at stake the prognosis of fertility after embolization are considered as a brake to its use for the treatment of infertility associated with myoma. Secondary hysterectomy and permanent amenorrhea are the two main risks. But they are not so frequent and can be prevented. To date, the experience in the field of fertility and pregnancy after arterial embolization for fibroids is quite limited. However, first results are encouraging and not very different from those observed after surgical myomectomy. A therapeutic trial using arterial embolization for the management of fibroids within a context of infertility can be devised in the presence of submucosal or intramural myomas responsible for metromenorrhagia and with no major infertility factors associated. It is likely that uterine artery embolization should provide results equivalent or superior to those of surgical myomectomy in case of numerous and intramural fibroids with no prevailing myoma. Arterial embolization could be also interesting in case of recurrent myoma after laparotomic myomectomy.

[Deep pelvic endometriosis: management and proposal for a "surgical classification"].
Deep pelvic endometriosis presents essentially in the form of a painful syndrome dominated by deep dyspareunia and painful functional symptoms that recur according to the menstrual cycle, with the semiology directly correlated with the location of the lesions (bladder, rectum). It is essential to investigate these deep endometriosis lesions and draw up a precise map, which is the only way to be sure that exeresis will be complete. The treatment of first intention remains surgery, and medical treatment is only palliative in the majority of cases. Success of treatment depends on how radical surgical exeresis is. Based on analysis of the anatomical distribution of deep pelvic endometriosis lesions, a "surgical classification" is proposed with the aim of establishing standard modes for surgical treatment. Further studies are required to clarify the place and modes for pre- and postoperative medical treatment.

[Ectopic pregnancy: interest and value of clinical examination in management policy].
Clinical examination (history and physical examination) is not considered to be a useful tool in the diagnosis of ectopic pregnancy (EP). In this systematic review we aimed to evaluate its value when ancillary tests are not readily available or when they are equivocal. Suspicion of EP is based on the presence of one or more of the following signs: vaginal bleeding, acute pelvic pain, or any risk factors for EP occurring in a pregnant woman. Detection of early pregnancy by urinary or serum hCG testing must be systematic because neither medical history nor physical examination can rule out early pregnancy with a high level of confidence. No isolated sign has sufficient diagnostic accuracy to rule out EP. In presence of vaginal bleeding without pain and if abdominal and pelvic examination are normal the risk of EP is very low. The presence of spontaneous pain moderate to severe, peritoneal signs, or definite pain during digital cervical mobilization increase the probability of EP. Absence of these signs does not rule out EP but tend to eliminate tubal rupture. In the presence of these signs one may consider an emergency transfer in a specialized center. In their absence, suspicion of EP may have outpatient diagnosis procedures.

Comparison of magnetic resonance imaging and transvaginal ultrasonography in diagnosing bladder endometriosis.
STUDY OBJECTIVE: To take recent progress in magnetic resonance imaging (MRI) into account to determine its accuracy compared with that of transvaginal ultrasonography (TVUS) in diagnosing bladder endometriosis. DESIGN: Retrospective analysis (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. PATIENTS: Twelve women with histologically proved bladder endometriosis. INTERVENTION: Magnetic resonance imaging with body and endocavitary coils and TVUS. MEASUREMENTS AND MAIN RESULTS: Although TVUS was normal in four patients, MRI enabled endometriotic lesions to be detected in all patients. Magnetic resonance imaging with endocavitary coil established the existence of deep infiltration in three patients when muscularis involvement was not visible with the body coil. In seven women MRI determined how far deep posterior endometriotic lesions extended, whereas with TVUS this was impossible to see. Conclusion. MRI had advantages over TVUS in diagnosing small lesions of associated posterior deep endometriotic lesions. The endocavitary coil gave better results than the phased-array coil for diagnosing deep infiltration. These results are important in that they help guide surgical management.

[Laparoscopic treatment of genital prolapse: lateral utero-vaginal suspension with 2 meshes. Results of a series of 47 patients].
We report our experience with a new technique to treat genital prolapse: the laparoscopic lateral suspension with two meshes. This is a prospective longitudinal study of 47 women with genital prolapse. With a mean follow-up of 15.2 +/- 10 months (1-39), the anatomical result was perfect in 78.7% of the cases (37 patients). From the functional point of view, 89.3% were satisfied (42 patients). These good preliminary results need to be confirmed by other extensive studies.

Laparoscopic surgery is not inherently dangerous for patients presenting with benign gynaecologic pathology. Results of a meta-analysis.
BACKGROUND: Laparoscopic surgery presents a large number of advantages over laparotomy. The goal of this work was to check whether these benefits outweigh any greater risk of complications. METHODS: The study design was a meta-analysis of published data from prospective randomized clinical trials (RCT). For the period 1966 to June 2000 we searched Medline and Cochrane Controlled Trial Registers and asked the investigators for further details. Meta-analysis was carried out with the Cochrane review manager software RevMan 4.1. RESULTS: A total of 27 prospective RCT including 3611 women (1809 treated by operative laparoscopy and 1802 treated by laparotomy) were enrolled in the meta-analysis. The overall risk of complications was significantly lower for patients operated by laparoscopic surgery [relative risk (RR) 0.59; 95% confidence interval (CI) 0.50-0.70]. There was no statistically significant difference concerning the risk of major complications with respect to the approach used (RR 1.0; 95% CI 0.60-1.65). The risk of minor complications was significantly lower for patients operated by laparoscopic surgery (RR 0.55; 95% CI 0.45-0.66). Concerning the risks of readmission, second procedure and blood transfusion, there was no difference between the two groups. Identical results were found when we performed a sensitivity analysis including or excluding studies according to the methodological score. Subgroup analysis according to how serious the surgery was (minor, major, advanced) showed a significant increase in the risk of transfusion for advanced procedures performed by laparotomy. CONCLUSIONS: Laparoscopic surgery is not inherently dangerous for patients presenting benign gynaecological pathologies. The potential risk of complications should no longer be advanced as an argument against using laparoscopic surgery rather than laparotomy for an operation when the indication allows the choice.

Adhesion formation after laparoscopic resection of uterosacral ligaments in women with endometriosis.
STUDY OBJECTIVE: To analyze the risk of postoperative adhesions in women who undergo laparoscopic surgical management of deep endometriosis infiltrating the uterosacral ligaments (USL). DESIGN: Retrospective analysis (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. PATIENTS: Forty-six women with deep endometriosis infiltrating the USL. INTERVENTION: Laparoscopic resection of all USL with deep endometriotic lesions and excision of all other endometriotic lesions, followed by second-look laparoscopy. MEASUREMENTS AND MAIN RESULTS: At second-look laparoscopy, 15 patients (32.6%) had no adhesions at the site where the USL had been resected, 24 (52.2%) had filmy avascular adhesions, and 7 (15.2%) had dense or vascular adhesions. No patient had adhesions of the binding type. Only two factors, the revised American Fertility Association (rAFS) score at initial laparoscopy and surgical modality (unilateral resection of the right USL, unilateral resection of the left USL, bilateral resection of USL) had a statistically significant influence on the risk of postoperative adhesions occurring. After adjustment, the relation with initial rAFS stage and surgical modality remained significant in the stepwise logistic regression model. CONCLUSION: These encouraging results are particularly interesting for patients with infertility due to pelvic pain syndrome. Second-look laparoscopy should not be performed routinely after laparoscopic management of deep endometriosis infiltrating the USL. We propose that it be reserved for women with rAFS stages III and IV endometriosis, especially when lesions are located on the left side.

Recurrence of leiomyomata after laparoscopic myomectomy.
STUDY OBJECTIVE: To assess recurrence of leiomyomata after laparoscopic myomectomy (LM) and evaluate predictive factors of recurrence. DESIGN: Observational study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: One hundred ninety-six women. INTERVENTION: Laparoscopic myomectomy with mean follow-up of 47 months. MEASUREMENTS AND RESULTS: Myoma recurrence included recurrence of initial symptomatology before LM, recurrence at clinical examination, and appearance of a myoma 2 cm or larger on ultrasound examination. Recurrence was observed in 45 patients (22.9%). The mean time before recurrence was 42 months (range 4-95 mo). Eight women (4.08%) required reoperation. The cumulative recurrence risk was 12.7% at 2 years and 16.7% at 5 years. Predictive factors for recurrence were number of myomas and nulliparity. CONCLUSION: According to our results, the cumulative rate of myoma recurrence within 5 years appears greater after LM than after laparotomy. However, this should not lead us to reject laparoscopy, which has many advantages compared with laparotomy, in particular its low morbidity.
