Endoscopic surgery in gynecologic practice.

In recent decades, the operative approach for several gynecologic diseases has changed from laparotomy to laparoscopy. New techniques and indications are continuously being developed. Laparoscopy offers a lot of advantages for the patient, but still a lot of additional data are required to determine the exact indications. Operative laparoscopy requires not only skill and experience, but also specialized equipment and paramedical staff. The most important topics for the gynecologist will be reviewed in this article.

Bilateral salpingectomy does not compromise ovarian stimulation in an in-vitro fertilization/embryo transfer programme.

The question whether salpingectomy has a negative influence on ovarian function and the outcome of pregnancy in an in-vitro fertilization (IVF) and embryo transfer treatment programme is not yet answered. We performed a retrospective case-control study to investigate the possible negative effect of salpingectomy on ovarian response to human menopausal gonadotrophins (HMG) during IVF and embryo transfer. The study group was composed of 26 patients with bilateral salpingectomy. In 67 cycles we analysed different parameters of ovulation such as the number of days of ovarian stimulation, numbers of ampoules of HMG, pre-ovulatory oestradiol concentrations and the numbers of oocytes retrieved. These parameters were compared to a control group of 134 cycles in 134 women with healthy Fallopian tubes. No differences were found. Implantation ratio, pregnancy rate and outcome were the same in both groups. We conclude that bilateral salpingectomy had no detrimental effect on ovarian performance during IVF and embryo transfer treatment nor on the outcome.

Analysis of the risk factors with regard to the occurrence of ectopic pregnancy after medically assisted procreation.

In a retrospective study (1985-1989) based on data from the Centre for Reproductive Medicine in Brussels, a total of 23 ectopic pregnancies (2.24%) occurred after 3800 embryo, zygote or gamete transfers. This number was low compared with the data published elsewhere. Tubal damage was a major risk factor towards developing an ectopic pregnancy after in-vitro fertilization and embryo transfer. The number of ectopic pregnancies after the association of clomiphene citrate and human menopausal gonadotrophin (HMG) was significantly higher in patients with tubal (7.8%) and non-tubal indications (2.1%) compared with those stimulated with gonadotrophin-releasing hormone (GnRH) and HMG (2.18% and 0.84%, respectively). The number of replaced embryos was not associated with the rate of ectopic pregnancy and neither did transfer technique (intra-uterine or intra-Fallopian transfer) influence the ectopic pregnancy rate.
