Ballooning Esophagoscopy
By inserting the window plug shown in Fig. 6 the esophagus may be inflated and studied in the distended state. The folds are thus smoothed out and constrictions rendered more marked. Ether anesthesia is advocated by Mosher. The danger of respirator... Complications Following Esophagoscopy
These are to be avoided in large measure by the exercise of gentleness, care, and skill that are acquired by practice. If the instructions herein given are followed, esophagoscopy is absolutely without mortality apart from the conditions for which ... Difficulties Of Esophagoscopy
The beginner may find the esophagoscope seemingly rigidly fixed, so that it can be neither introduced nor withdrawn. This usually results from a wedging of the tube in the dental angle, and is overcome by a wider opening of the jaws, or perhaps by ... Entering The Bronchi
The lip of the bronchoscope should be turned in the direction of the bronchus to be explored, and the axis of the bronchoscope should be made to correspond as nearly as possible to the axis of this bronchus. The position of the lip is designated by ... Introduction Of The Esophagoscope
The esophagoscope is to be passed only with ocular guidance, never blindly with a mandrin or obturator, as was done before the bevel-ended esophagoscope was developed. Blind introduction of the esophagoscope is equally as dangerous as blind bouginag... Specular Esophagoscopy
Inspection of the hypopharynx and upper esophagus is readily made with the esophageal speculum shown in Fig. 4. High lesions and foreign bodies lodged behind the larynx are thus discovered with ease, and such a condition as a retropharyngeal absces... Stage 2
Passing the cricopharyngeus is the most difficult part of esophagoscopy, especially if the patient is unanesthetized. Local anesthesia helps little, if at all. The handle of the esophagoscope is still pointing upward and consequently we are sure tha... Stage 3 Passing Through The Thoracic Esophagus
The thoracic esophagus will be seen to expand during inspiration and contract during expiration, due to the change in thoracic pressure. The esophagoscope usually glides easily through the thoracic esophagus if the patient's position is correct. Af... Stage 4 Passing Through The Hiatus Esophageus
When the head is dropped, it must at the same time be moved horizontally to the right in order that the axis of the tube shall correspond to the axis of the lower third of the esophagus, which deviates to the left and turns anteriorly. The head and... Stage I Entering The Right Pyriform Sinus
The operator standing (as in Fig. 66), inserts the esophagoscope along the right side of the tongue as far as and down the posterior pharyngeal wall. A lifting motion imparted to the tip of the esophagoscope by the left thumb will bring the rounded... Technic Of Specular Esophagoscopy
Recumbent patient. Boyce position. The larynx is to be exposed as in direct laryngoscopy, the right pyriform sinus identified, the tip of the speculum inserted therein, and gently insinuated to the cricopharyngeal constriction. Too great extension ...
