Bezoars are concretions of plant or animal material in the gastrointestinal tract. The term bezoar is derived from the Persian "padzahr" meaning counterpoison or antidote.3The classic review of 311 patients was published by DeBakey and Ochsner4in 1939. Symptoms range from early satiety, nausea, vomiting, and epigastric pain to obstruction and perforation. Physical findings include the presence of a nontender palpable mass. Computed tomographic examination may show an intraluminal mass without attachment to bowel wall and presence of air within the mass. Treatment depends on the composition of the bezoar. Plant bezoars (phytobezoars) may be dissolved with various enzymes. Trichobezoars (hair) are often resistant to enzymatic dissolution and require endoscopy for removal. Surgical removal is indicated when enzymatic dissolution and endoscopy are unsuccessful.
