Fetoscopes

Abstract: One of the major goals in modern obstetrics is to provide more detailed informations of prenatal fetal physiology. Since 1972, more than 200 amniocentesis were performed in our hospital and the importance of prenatal genetic diagnosis has been recognized. But amniocentesis has the limitations which are 1) the lack of expression of many single gene hereditary disorders in amniotic fluid and its cells, 2) the large percentage (90%) of nonviable fetal cells in any given sample, 3) the length of time required to culture fetal cells. Accordingly the necessity of development of other methods to obtain further direct data on the fetus from the uterine cavity has been indicated. Among gynecological endoscopies, fetoscopy which is direct visualization of the fetus by introduction of an endoscope into the amniotic cavity is expected to obtain direct information from the uterine environment in pregnant women. By our newly developed fetoscope, we investigated clinical indications and contraindications of fetoscopy as well as future possibilities of this endoscope. Our present study indicates that further developments and future benefits of fetoscopy entirely depend on the progress of laboratory techniques which can provide more accurate data through specimens obtained fetoscopy.
