bezoar
Pronunciation: BEE-zohr
A mass of indigestible material that accumulates in the stomach or intestines.
Full Definition
A bezoar is a solid mass composed of indigestible material that forms and accumulates within the gastrointestinal tract, most commonly in the stomach. In pediatric patients, bezoars can be classified by their composition: phytobezoars (plant material), trichobezoars (hair), pharmacobezoars (medications), or lactobezoars (formula or milk). Children with developmental delays, pica, or trichotillomania are at increased risk. Bezoars may cause symptoms ranging from mild abdominal discomfort to complete gastric outlet obstruction. Large trichobezoars may extend into the small intestine (Rapunzel syndrome). Treatment options include endoscopic removal, enzymatic dissolution, or surgical extraction depending on size and composition.
Usage
Usage note: Specify type (tricho-, phyto-, pharmaco-, lacto-) when known; note Rapunzel syndrome if applicable.
