Retrieval of Dropped Hood

Whereas a hood left caudal to the stenotic site is spontaneously excreted in the feces, a hood left proximal to the site may be retained in the gastrointestinal tract as a foreign body. Spontaneous excretion is unlikely, particularly when the dilatation is unsatisfactory. The hood should be retrieved after a series of interventions. It can be retrieved simply by reinserting the endoscope into the overtube that had been left in place, grasping the hood with a basket catheter (FG-33W, Olympus) under endoscopic guidance, and removing the endoscope together with the overtube (Fig. 11.4.13).
