Gastric trichobezoar: case report and literature review

Mayo Clin Proc. 1998 Jul;73(7):653-6. doi: 10.1016/S0025-6196(11)64889-1.


Bezoars are conglomerates of food or fiber in the alimentary tract of humans and certain animals, mainly ruminants. In adults, bezoars are most frequently encountered after a gastric operation, but in children, bezoars are associated with pica, mental retardation, and coexistent psychiatric pathologic disorders. We describe a 4-year-old girl with trichotillomania in whom a gastric trichobezoar resulted in failure to gain weight, iron deficiency anemia, and a painless epigastric mass. The causes of gastric bezoars are discussed, with emphasis on diagnostic considerations, treatment options, and preventive measures.
