One of the most difficult and disturbing problems of endoscopy has been the removal of foreign bodies from the stomach. Even the use of the gastroscope and the flexible forceps under biplane fluoroscopic guidance does not circumvent such difficulties. The constant shifting of the position of the foreign body, in a space as large as the stomach, makes it difficult to establish contact between the forceps and the object.
Herewith is presented the description of a magnet1 of cast alnico which has proved highly gratifying in cases of magnetizable foreign bodies in the stomach and tracheobronchial tree. As shown in figure 1, the magnet is 3.5 cm. in length and 0.5 cm. in diameter and is attached to a levine tube, size 12 E, through which a metal stylet has been inserted to increase the mobility of the tube. The other end of the levine tube is
