Abstract

Approaches to the removal of mosaic by special decomposition, composition and image scanning are discussed. This provided 6 times larger volume of the information transmitted. A principle of choosing parameters for endoscope oculars is offered and pictures showing ways to bend their distal end are presented.

Endoscopy of the lacrimal outflow system.

Management of obstructions in the lacrimal drainage system would be greatly aided by improvements in the ability to visualize the blockages. We describe a new method of observation using miniature fiberoptics to view the entire lacrimal excretory system. We employed flexible endoscopes of fiberoptic bundles with outside diameters of from 0.5 to 0.7 mm. These endoscopes were inserted through the puncta and canaliculi. Sixteen patients were examined. A range of pathologic conditions were found, including slightly stenosed passages and severely destroyed canalicular mucosal lining. Our results indicate that this technique is feasible and useful in the diagnosis of lacrimal excretory disease.

Neuroendoscopic technique for the operative treatment of septated syringomyelia.

The management of septated, chambered syringomyelia has until now been problematic because the usual operative methods cannot secure drainage of all chambers of the cavity. The development of a flexible neuroendoscope affords the possibility to perforate the septa under visual control which subdivide the cavity. We present our experiences with 11 cases of septated syringomyelia, which have been operated upon using a flexible neuroendoscope.

Embryoscopy: a closer look at first-trimester diagnosis and treatment.

Advancing technology has made the fetus and its environment even more accessible to prenatal diagnosis and treatment. The current approach to prenatal diagnosis relies mainly on the use of high-resolution ultrasonography. However, as attempts are made to conduct antenatal diagnoses earlier in gestation, the limits of ultrasonography are approached. Embryoscopy allows for direct visualization of the first-trimester fetus with a fiberoptic endoscope. A customized side channel enables the operator to pass a variety of diagnostic tools and gain access into the fetal circulation. The further development and refinement of this technology are expected to change early prenatal diagnosis and treatment considerably. The potential contribution of this technique to perinatal medicine is readily apparent when it is placed in historic context. Undoubtedly, many ethical, legal, and regulatory questions will have to be addressed before the full potential of embryoscopy is realized. The responsibility for the judicious use of this powerful technology for prenatal intervention will have to be shared by the scientific community and a well-informed public.
