title: Bezoars in children: report of four cases.
abstract: We reviewed the histories of four children (2 boys and 2 girls, aged 6 mo to 10 yr) with surgically proven bezoars, treated from 1991 to 1998. Two had gastric bezoars and two had intestinal bezoars. All four patients presented with gastrointestinal symptoms and none had undergone previous surgery. Three had a history of abnormal ingestion, including one who ate a pickled fruit from the Boraginaceae (locally known as Po-pu-tsu) plant for 1 year. Plain radiographs revealed intestinal obstruction in all four patients. Abdominal sonography disclosed a hyperechoic band-like lesion and acoustic shadow in both cases of gastric bezoar, and these bezoars were subsequently confirmed by gastric endoscopy. Lower gastrointestinal studies showed obstruction considered most likely to be due to bezoar in one case, while computed tomography (CT) revealed a characteristic small bowel mottled gas pattern in another. Surgical treatment relieved obstruction in all four patients. Bezoar should be suspected in patients with intestinal obstruction who have a history of ingestion of unusual substances. The findings of this report suggest that sonography and endoscopy are useful in the diagnosis of gastric bezoar, while CT is useful in the detection of intestinal bezoar.
