Bezoars are collections or concretions of indigestible foreign material in the gastrointestinal tract. In the past, the most common method for the treatment of bezoar was surgical management. The current treatment methods for bezoars include chemical dissolution and endoscopic lithotripsy using biopsy forceps and, snare, electrohydraulic lithotripsy and laser. Cases of endoscopic fragmentation of gastric bezoars using an argon plasma and dissolution of gastric bezoars with Cola have recently been described, but it took a long time in those cases to remove a bezoar by a single method. Moreover, fragmented, residual bezoar-related complications sometimes occurred. We report here on a case of a 35-year-old man with a 10x8x8 cm sized huge gastric bezoar that was successfully removed by combination therapy using an argon plasma and Coca-Cola injection. Compared with the previous single method, combination therapy using an argon plasma and Coca-Cola injection shortened the procedure time and reduced the complications related to a fragmented, remaining bezoar.
