2009 URMC Imaging Sciences
Publication Date: 2010-03-09
A bezoar is any type of indigestible material that accumulates in the gastrointestinal tract, most commonly the stomach. There are many different types of bezoars, depending on the etiology and composition. Different materials include hair (trichobezoars) or vegetable fiber (phytobezoars).
There is a female predominance of more than 50%. Predisposing factors include any etiology for gastric paresis including narcotics or vagotomy. Symptoms include anorexia, bloating, and early satiety. It may cause small bowel obstruction after forming in the stomach.
The radiographic findings are of a mass in the gastric lumen which mimics food. Barium studies demonstrate a filling defect with contrast seeping into the heterogeneous mass. Delayed films are helpful because the barium will be retained in the bezoar.
