Chevalier Jackson Lecture. Analysis of new optical systems in bronchoesophagology.
A new image transmitting system (Hopkins rod lens) made it possible to redesign the entire armamentarium of rigid broncho- and esophago- laryngology. The introduction of an optical biopsy forceps made tissue sampling more accurate. The increased light transmission produces a brighter image and easier perception. The larger viewing angle facilitates orientation. The new miniature pediatric bronchoscope, with a telescope, changed the pinpoint vision to a panoramic view. The optical foreign body forceps is of great help in fast and precise manipulations. The indirect laryngoscope proved to be a great investigative tool with the capability to obtain, with ease, a movie filmstrip for detailed analysis in the outpatient clinic. The introduction of the flexible fiber bronchoscope brought new dimensions in tissue sampling of peripheral lesions, treatment of pulmonary complications in the intensive care units, and became an important aid in intubating patients with difficult anatomy. The possibility to obtain moive films and to study our visual findings, at leisure, is an important diagnostic and teaching aid.
