ENDOSCOPIC REMOVAL OF FOREIGN BODY IN THE UPPER GASTROINTESTINAL TRACT USING ACONE-SHAPED HOOD

-APPLICATION TO TWO CASES OF A SWALLOWED DENTURE

Abstract

Hooded endoscopy is a technique for removing foreign bodies in the upper gastrointesfinal tract using a fiberscope attached with a cone-shaped hood on the tip. We applied hooded endoscopy to 2 cases of swallowed artificial denture where extraction with ordinary endoscopic removal technique had failed. In this technique, the swallowed denture was pulled into the hood by a grasping forceps and easily extracted with the fiberscope through the cardia and pharyngo-esophageal junction without mucosal injuries. The hood used in this study covered the irregular surface and sharp edges of the denture. In addition, it could cover a denture larger than the diameter of the fiberscope in size. Hooded endoscopy was considered to be an applicable technique to endoscopic removal of a swallowed denture.
