Gastric trichobezoar presenting as gastric outlet obstruction--a case report.

Trichobezoars are impactions of swallowed hairs in the stomach and occasionally in the intestine. They occur in emotionally disturbed, depressed, or mentally retarded patients who have trichotillomania and trichophagia. Removal of gastric trichobezoar by open surgery (gastrotomy) is a standard approach.
