Discussion of Bezoar
- Bezoars consist of ingested foreign materials that accumulate within the gastrointestinal tract and are classified according to the materials of which they are composed.
- Trichobezoars (hair) and phytobezoars (fruit/vegetable) are the most frequent forms.
- Bezoars usually form in the stomach and can pass into the small bowel where they occasionally cause small bowel obstruction.
- Predisposing factors include inadequate chewing, high-fiber diets, and previous gastric surgery.
