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 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.

Case ReportsEndobronchial foreign body removal using the bronchofiberscope.
In certain situations the flexible fiberoptic bronchoscope can augment rigid bronchoscopy in foreign body removal. A case of a successful fiberoptic removal of an endobronchial foreign body (dental bridge) is presented. A wire basket, inserted through the channel of the bronchofiberscope, was used to capture the object.

An animal model of subglottic stenosis has been developed. The results of this pilot study show evidence to suggest that injury to the cricoid cartilage leading to perichondritis is the important factor in the development of subglottic stenosis.

A 2 1/2-year-old child was found to have subglottic stenosis with no obvious etiology. He initially responded well to dilatation, injection of triamcinolone and intermittent stenting of the airway, but four months later developed a marked, unyielding subglottic stenosis requiring tracheostomy. He had a gradual good response to dilatations and injections with triamcinolone and acquired a good subglottic lumen. ⋯ Subglottic stenosis may be congenital, traumatic, inflammatory, neoplastic or neurogenic. An additional group of patients has no obvious etiology and are classified as idiopathic. Treatment consists of various combinations of stents, systemic and intralesional steroids, dilatations and various operative procedures in the more refractory cases.

Case ReportsFatal complication from an alkaline battery foreign body in the esophagus.
Foreign bodies and alkali burns in the trachea and esophagus are potentially fatal. Some camera batteries contain 45% potassium hydroxide electrolyte which can leak and cause liquification necrosis upon tissue contact. This report describes a case of an alkali battery foreign body in the esophagus with a subsequent fatal course which was masked by steroid therapy. A discussion of corrosive burns of the esophagus, their etiology, clinical course and pathology is presented.
