Endoscopic removal of sharp and pointed foreign bodies in the upper gastrointestnal tract still poses technical difficulties. We present here our experience with a new endoscopic end lucent skirt protector having the unique characteristic of maintaining its bell portion inverted during the progression of the scope through the gut and flipping back to its 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 large sharp and pointed dental prosthesis in the fourth part of the duodenum. We belived that this device enhance the safe removal of a wide variety of potentially dangerous gastroesophageal foreign bodies.
