Bronchoscopy and Esophagoscopy

Bronchoscopy and Esophagoscopy - A Manual of Peroral Endoscopy and Laryngeal Surgery

This book is based on an abstract of the author's larger work, Peroral Endoscopy and Laryngeal Surgery. The abstract was prepared under the author's direction by a reader, in order to get a reader's point of view on the presentation of the subject in the earlier book. With this abstract as a starting point, the author has endeavored, so far as lay within his limited abilities, to accomplish the difficult task of presenting by written word the various purely manual endoscopic procedures. The large number of corrections and revisions found necessary has confirmed the wisdom of the plan of getting the reader's point of view; and these revisions, together with numerous additions, have brought the treatment of the subject up to date so far as is possible within the limits of a working manual. Acknowledgment is due the personnel of the W. B. Saunders Company for kindly help. Direct laryngoscopy, bronchoscopy, esophagoscopy and gastroscopy are procedures in which the lower air and food passages are inspected and treated by the aid of electrically lighted tubes which serve as specula to manipulate obstructing tissues out of the way and to bring others into the line of direct vision. Illumination is supplied by a small tungsten-filamented, electric, "cold" lamp situated at the distal extremity of the instrument in a special groove which protects it from any possible injury during the introduction of instruments through the tube. The bronchi and the esophagus will not allow dilatation beyond their normal caliber; therefore, it is necessary to have tubes of the sizes to fit these passages at various developmental ages. Rupture or even over-distention of a bronchus or of the thoracic esophagus is almost invariably fatal. The armamentarium of the endoscopist must be complete, for it is rarely possible to substitute, or to improvise makeshifts, while the bronchoscope is in situ. Furthermore, the instruments must be of the proper model and well made; otherwise difficulties and dangers will attend attempts to see them. Laryngoscopes.The regular type of laryngoscope shown in Fig. I (A, B, C) is made in adult's, child's, and infant's sizes. The instruments have a removable slide on the top of the tubular portion of the speculum to allow the removal of the laryngoscope after the insertion of the bronchoscope through it. The infant size is made in two forms, one with, the other without a removable slide; with either form the larynx of an infant can be exposed in but a few seconds and a definite diagnosis made, without anesthesia, general or local; a thing possible by no other method. For operative work on the larynx of adults, such as the removal of benign growths, particularly when these are situated in the anterior portion of the larynx, a special tubular laryngoscope having a heart-shaped lumen and a beveled tip is used. With this instrument the anterior commissure is readily exposed, and because of this it is named the anterior commissure laryngoscope (Fig. 1, D). The tip of the anterior commissure laryngoscope can be used to expose either ventricle of the larynx by lifting the ventricular band, or it may be passed through the adult glottis for work in the subglottic region. This instrument may also be used as an esophageal speculum and as a pleuroscope. A side-slide laryngoscope, used with or without the slide, is occasionally useful. ......Buy Now (To Read More)
