An unusual cause of gastrointestinal obstruction: bezoar
1Department of Pediatric Surgery, Hamad General Hospital, Doha, Qatar.
Abstract:
Bezoars are concretions of swallowed hair, fruit vegetable fibers, and similar substances found in the alimentary canal. The first description of a postmortem human bezoar was by Swain in 1854. Although the prevalence of bezoars in humans is low, an absence of treatment has been associated with mortality rates as high as 30%, primarily because of gastrointestinal bleeding, destruction, or perforation.
