The objective of this study was to identify the prognostic factors for conception after myomectomy carried out in cases of infertility. A total of 91 infertile patients presenting at least one subserous or intramural myoma measuring >2 cm underwent myomectomy. The characteristics of the patients, myomata and associated infertility factors were collected in a uniform and systematic way. A postal questionnaire was sent to patients. For each of the various factors studied, the specific cumulative probability of spontaneous intrauterine conception was estimated using the Kaplan-Meier method. Multiple regression analysis was then carried out using Cox's proportional hazards model. The cumulative probability of spontaneous intrauterine conception at 2 years follow-up was 44% (95% confidence interval: 32-56%). The cumulative probability of conception was less after removal of a posterior or intramural myoma, after a sutured hysterotomy, and when accompanied by a male factor, associated tubal or ovulation pathology. The cumulative probability of conception was greater after ablation of myomata responsible for menometrorrhagia. The size, deforming effect on the cavity and age played no role in our sample. Our results indirectly suggest that post myomectomy adhesions could have an adverse effect on fertility. Myomata responsible for menometrorrhagia are also the cause of infertility. In the presence of an associated male, tubal or ovulatory factor, the results were poor and it was not possible to determine if a myomectomy should be performed in these cases in order to enhance fertility.

BACKGROUND AND STUDY AIMS: The main area of the gastrointestinal tract affected by deep pelvic endometriosis is the rectosigmoid colon in 3-37% of cases. Due to the risk of infiltration and the clinical symptoms of endometriosis, with pain and infertility, the condition may require surgical resection. Preoperative imaging diagnosis of rectosigmoid involvement is therefore important. Rectal endoscopic ultrasonography (EUS), which is already used for the staging of anorectal carcinoma and submucosal lesions, may be a promising technique for this indication. The present study was conducted in order to describe the endosonographic appearance of rectosigmoid endometriosis, and to define the potential relevance of the technique to the choice of resection method. PATIENTS AND METHODS: Between 1993 and 1997, 46 women (mean age 31) with deep pelvic endometriosis underwent imaging investigations and surgical resection. The clinical and imaging findings, and the surgical and histological features identified--mainly with regard to infiltration of the rectal wall--were compared retrospectively. The impact of the EUS findings on the decision on whether or not to carry out resection, either by laparoscopy or open abdominal surgery, was also examined. RESULTS: When there was deep pelvic endometriosis with suspected rectal wall infiltration, EUS showed normal anatomy in nine patients, endometriotic lesions without rectal wall infiltration in 12, and typical rectal infiltration in 25. The lesions were confirmed by the surgical findings during therapeutic laparoscopy (n = 22) and laparotomy (n = 25), as well as by clinical follow-up. Rectal wall infiltration, demonstrated in all cases using EUS, had initially been suspected on the basis of clinical examinations, rectoscopy, barium enema, computed tomography, and magnetic resonance imaging in 62%, 50%, 33%, 67% and 66% of cases, respectively. CONCLUSIONS: EUS is a simple and noninvasive technique capable of correctly diagnosing rectal wall infiltration in deep pelvic endometriosis. It may be helpful in determining the choice between laparoscopy and laparotomy when complete resection is indicated.

• 07/2000

The work presented here demonstrates the utility of the integrated cell culture-reverse transcriptase-polymerase chain reaction (ICC-RT-PCR) coupled with nested PCR to detect human astroviruses and enteroviruses in sludge biosolids. Viruses were concentrated by beef extract elution and organic flocculation prior to analysis by a plaque assay and ICC-RT-PCR. Astroviruses were detected in all but one sample and all of the samples were positive for enteroviruses. We have demonstrated the prevalence and frequency ofastrovirus in sludge and validated the ICC-RT-PCR/nested PCR technique as a useful tool to detect viruses in sludge.

[Treatment of ectopic pregnancy in 2000].

Operative laparoscopy is currently the best treatment for pregnancy (EP). As with laparotomy, laparoscopic treatment of EP can be either conservative (salpingotomy or radical (salpingectomy). After conservative laparoscopic treatment, failures are diagnosed by monitoring the drop in beta-hCG levels. Fertility results after laparoscopic treatment of EP are comparable with those observed after similar treatment by laparotomy. Better knowledge o the risk factors of EP, development of hCG assays using serum progesterone and high resolution sonography using vaginal probes allow early diagnosis of EP and a nonsurgical approach in more than 30% of cases. When inclusion criteria are strict, methotrexate administered by local injection or systemically (1mg/kg) in a single dose or in combination with mifepristone gives a 90 to 95% success rate. Whatever treatment protocol is used, fertility prognosis after EP is not correlated to the features of EP but depends mainly on patient age and past history.

We evaluated the use of an integrated cell culture-reverse transcription-PCR (ICC-RT-PCR) procedure coupled with nested PCR to detect human astroviruses, enteroviruses, and adenovirus types 40 and 41 in surface water samples that were collected and evaluated by using the Information Collection Rule (ICR) method. The results obtained with the ICC-RT-PCR-nested PCR method were compared to the results obtained with the total culturable virus assay-most-probable-number (TCVA-MPN) method, the method recommended by the U.S. Environmental Protection Agency for monitoring viruses in surface and finished waters. Twenty-nine ICR surface water samples were analyzed. Viruses were concentrated by using filter adsorption-beef extract elution and organic flocculation techniques, and then the preparations were evaluated for viruses by visualizing cytopathic effects in the Buffalo green monkey kidney (BGMK) cell line. In the ICC-RT-PCR-nested PCR technique we used Caco-2 cells to propagate astroviruses and enteroviruses (ICC step), and we used BGMK cells to propagate adenovirus types 40 and 41, as well as enteroviruses. Fifteen of the 29 samples (51.7%) were positive for astrovirus as determined by the ICC-RT-PCR-nested PCR method, and eight of these samples (27.5%) contained infectious astrovirus. Seventeen of the 29 samples (58.6%) were positive for enteroviruses when the BGMK cell line was used, and six (27.6%) of these samples were determined to be infectious. Fourteen of the 29 samples (48.3%) were positive for adenovirus types 40 and 41, and 11 (37.9%) of these samples were determined to be infectious. Twenty-seven of the 29 samples (93.1%) were positive for a virus, and 19 (68.9%) of the samples were positive for an infectious virus. Only 5 of the 29 samples (17.2%) were positive as determined by the TCVA-MPN method. The ICC-RT-PCR-nested PCR method provided increased sensitivity compared to the TCVA-MPN method.

Uterine rupture after myomectomy by laparotomy is not a common occurrence. Some case reports of uterine rupture after laparoscopic myomectomy (LM) raise the question of the quality of the uterine scar produced when this technique is performed. In order to assess the outcome of pregnancies and deliveries after LM and to assess the risk of uterine rupture, we performed an observational study. Questionnaires were mailed to all women who had had LM for at least one intramural or subserosal myoma of more than 20 mm diameter and who were aged <45 years. Ninety-eight patients became pregnant at least once after LM, giving a total of 145 pregnancies. Among the 100 patients who had delivery, there were three cases of spontaneous uterine rupture. Because only one of these uterine ruptures occurred on the LM scar, the risk of uterine rupture was 1.0% (95% CI 0.0-5. 5%). Seventy-two patients (72.0%) had trials of labour. Of these, 58 (80.6%) were delivered vaginally. There was no uterine rupture during the trials of labour. Spontaneous uterine rupture seems to be rare after LM. This risk should not deter the use of LM if needed. When performing LM, particular care must be given to the uterine closure.

OBJECTIVES: The aim of this study is a direct costs comparison between laparoscopic and abdominal total hysterectomy when theses procedures are indicated for benign pathologies. STUDY DESIGN: To this end we compared the direct costs of total laparoscopic hysterectomy (TLH) calculated from a series of 105 patients with that obtained for a comparable series of 30 patients who underwent hysterectomy by laparotomy. RESULTS: The direct costs of total hysterectomy for a benign pathology by laparoscopic surgery and laparotomy are comparable (respectively 7693 French francs (FF) and 7759 FF). Whatever the type of operation the cost for staff represents 60% of the total cost. Expenditure for staff during the operation represents 41.0% of the total cost of TLH (3154 FF/7693 FF) whereas it represents only 31.0% of the cost of the operation when carried out by laparotomy (2406 FF/7759 FF) (P<0.0001). Inversely the expenditure due to staff during the post operative phase represents 24.1% of the total cost of the operation when laparotomy is used (1875 FF/7759 FF) and only 13.4% of the cost of the operation by laparoscopic surgery (1029 FF/7693 FF) (P<0.0001). When the operation uses laparoscopic surgery the increase in expenditure during the surgical act is compensated by the statistically significant shortening in the hospital stay. Expenditure connected with the laparoscopic surgery equipment is minimal compared to the costs connected with the staff. CONCLUSION: Provided that TLH is carried out with reusable laparoscopic surgery equipment, by skilled surgeons working in suitable hospital structures making the particularly heavy investment in laparoscopic surgery equipment economically viable, TLH is an economically viable technique as an alternative to laparotomy.
