esophagoscope

Bougies should be introduced under visual guidance through the esophagoscope, which is so placed that the lumen of the stricture is in the center of the endoscopic field.

The mouth should be gently opened and a bite block (Fig. 16) inserted between the teeth on the left side of the patient's mouth, to prevent closing of the jaws on the delicate bronchoscope or esophagoscope.

During practice work the value of the beveled lip of the bronchoscope and esophagoscope in solving mechanical problems will be evidenced.

A white, pasty, macerated mucosa, and normally contracted hiatus esophageus which when found permits the large esophagoscope to pass into the stomach, will be recognized as characteristic by anyone who has seen the condition.

- The esophagoscope, like the bronchoscope, is a hollow brass tube with beveled distal end containing a small electric light.

Thus, if an esophagoscope 45 cm. long be introduced and we find that the distance from the incisor teeth to the ocular end of the esophagoscope as measured by the rule is 20 cm., we subtract this 20 cm. from the total length of the esophagoscope (45 cm.) and then know that the distal end of the tube is 25 cm. from the incisor teeth.

As the bronchoscope or esophagoscope is further inserted, the head must be placed so that the tube corresponds to the axis of the lumen of the passage to be examined.

This is readily done by measuring the distance from the proximal end of the esophagoscope to the upper incisor teeth, or in their absence, to the upper alveolar process, and subtracting this measurement from the known length of the tube.

The coiled spring is to be sought, and when found, seized with the rotation forceps and the pin thus drawn into the esophagoscope to effect closure.
