Gastric Diospyrobezoar Dissolution with Ingestion of Diet Soda and Cellulase Enzyme Supplement

Diospyrobezoars are a subtype of phytobezoars caused by excessive consumption of persimmons, which contain large amounts of tannins. In contrast to phytobezoars, diospyrobezoars have a harder consistency than other bezoars, making them more difficult to break up both chemically and endoscopically. We have previously reported successful dissolution of phytobezoars with diet soda and cellulase. A review of the literature found low efficacy of soda in dissolving diospyrobezoars compared to other phytobezoars. We report a case of successful dissolution of a diospyrobezoar after a failed attempt with diet soda alone.
