Cap of a duodenoscope
Cap of a duodenoscope Cap in the dormia basket
During examination this loose cap of the duodenoscope fell off. It obliterates the esophageal lumen completely. Since the cap is made of soft rubber, it can be safely forwarded by pushing it carefully to the stomach with the scope itself. The cap is caught by means of a dormia basket.
Cap in overtube A transparent plastic overtube is inserted to the proximal esophagus to protect it (and also the upper respiratory tract) from mucosal lesions inflicted by sharp edges of foreign bodies (i.e.:parts of dentures). Aspiration of the cap into the trachea is also prevented.
