Bezoar: an uncommun cause of upper gastrointestinal bleeding.

Bezoars are aggregates of non-digestible material that accumulate in the gastrointestinal tract. They can be classified according their composition and phytobezoars (composed by vegetable or fruit fiber) is the most common type. They occur more often in patients with some risk factors, namely prior gastric surgery, neuropsychiatric, endocrine or other disorders that lead to abnormal gastric function or poor gastric peristalsis (2). Bezoars may be asymptomatic but most commonly cause abdominal discomfort or pain, nausea, vomiting, fullness, difficulty in swallowing or anorexia and weight loss. Upper GI endoscopy for both diagnostic and therapeutic purposes is the key in the managment of bezoars.
