Photographs of the in vitro experiment. A: Endoscopically extracted fragments of the gastric bezoar were used; B: Representative photographs of the bezoar fragments incubated at 37 °C with gentle swirling for 12 h with double-distilled water; C: Bezoar fragments after incubation with Coca-Cola^®; D: Bezoar fragments after incubation with Coca-Cola Zero^®; E: Bezoar fragments after incubation with a digestive enzymes supplement including cellulase; F: Bezoar fragments after incubation with papain. The bezoar fragments were clearly more softened and more fragmented after 12-h incubation with Coca-Cola^® or Coca-Cola Zero^® than with the other agents.
