Endoscopic removal of sharp and pointed foreign bodies in the upper gastrointestinal tract still poses technical difficulties. Overtubes may be uncomfortable to the patients and only objects fitting within a lumen of about 11-15 mm can be removed. We present here our preliminary experience with a commercially available new endoscopic end protector hood having the unique characteristic of maintaining its bell portion inverted during the progression of the scope through the gut and flipping back to its original shape during withdrawal through the lower esophageal sphincter. This prevents exposure of the esophageal and pharyngeal wall to injuries from the edges of the foreign body. We used this device to remove nine large sharp or pointed gastroesophageal foreign bodies in six consecutive patients in whom conventional techniques were considered unsafe or not technically feasible owing to the size and shape of the objects. In all cases, removal was successful and easily performed without bowel damage. We believe that this device enhances the safe removal of a wide variety of potentially dangerous gastroesophageal foreign bodies.
