[Trichobezoars in children and adolescents].

BACKGROUND

Trichobezoars are composed of hair or fibres. The typical patient presenting with a trichobezoar is an adolescent girl experiencing mental disturbance or retardation.

CASE REPORT: Three girls with trichobezoars were seen. Two of them, 4 and 15 years old, had serious digestive antecedents (corrosive oesophagogastritis and oesophageal atresia, respectively) and had undergone previous surgery. The third was a 13-year-old mentally retarded girl. In two cases, an enzymatic dissolution trial was unsuccessful, requiring secondary surgical removal after, in one case, ineffective gastroscopic removal complicated by an oesophageal perforation. The third child had an initial operative removal.

DISCUSSION: Serious digestive antecedents may favour bezoars, a diagnosis that must be evoked in such patients presenting with chronic digestive symptoms. Enzymatic dissolution is ineffective for large bezoars, and gastroscopic removal carries some risks such as perforation or intestinal obstruction. Operative removal is usually indicated. Psychiatric follow-up is needed to prevent this complication in children with serious digestive antecedents and to reduce the risk of recurrences.
