Abstract

A 62-year-old woman with no past history was referred to our hospital for endoscopic treatment of a large gastric bezoar measuring 10 cm in diameter. The bezoar had a hard surface and huge volume. A tunnel was created at the center of the bezoar using electrohydraulic lithotripsy and was dilated using a through-the-scope balloon. The bezoar was then gradually crushed using alligator forceps and snares to decrease the risk of intestinal obstruction by the crushed bezoar fragments. The sequential use of electrohydraulic lithotripsy, alligator forceps, and snares according to the therapeutic plan enabled the endoscopic treatment of the giant gastric bezoar without surgery.

Keywords: electrohydraulic lithotripsy; endoscopic treatment; gastric bezoar.

(d) Balloon dilation is performed after electrohydraulic lithotripsy to enlarge the tunnel. (e) The bezoar is grasped using alligator forceps and gradually crushed. (f) The bezoar is crushed using alligator forceps and snares. (g) The giant bezoar is completely crushed and removed without complications. Large fragments of the bezoar are retrieved, and small fragments are allowed to pass into the intestine.
