Chevalier Jackson,
Bronchoscopy and Esophagoscopy
“ Symptoms.—Dysphagia is the most frequent complaint in cases of esophageally lodged foreign bodies. A very small object may excite sufficient spasm to cause aphagia, while a relatively large foreign body may be tolerated, after a time, so that the swallowing function may seem normal. Intermittent dysphagia suggests the tilting or shifting of a foreign body in a valve-like fashion; but may be due to occlusion of the by-passages by food arrested by the foreign body. Dyspnea may be present if the foreign body is large enough to compress the trachea. ”
