Endoscopy

Once the foreign body has been identified with the gastroscope, various devices can be passed through the gastroscope to grasp or manipulate the foreign body. Devices used include forceps, which come in varying shapes, sizes and grips, snares, and oval loops that can be retracted from outside the gastroscope to lasso objects, as well as Roth baskets (mesh nets that can be closed to trap small objects), and magnets placed at the end of the scope or at the end of orogastric tubes. Some techniques have been described that use foley catheters to trap objects, or use two snares to orient foreign bodies.
