Small bowel obstruction due to trichobezoar: Role of upper endoscopy in diagnosis

      Trichobezoars are foreign bodies composed of hair or fibers impacted in the stomach or the intestine of humans and certain animals. They are more common in children and adolescents and are usually associated with pica, serious psychiatric illness, or mental retardation. In most cases trichobezoars are present in the stomach, only rarely reaching into the small intestine. Trichobezoars are rare causes of small bowel obstruction. A patient with trichotillomania and trichophagia presented with manifestations of small bowel obstruction and was found to have gastric and jejunal trichobezoars. The epidemiology, etiology, clinical manifestations, diagnostic considerations, and treatment options are discussed, with emphasis on the role of upper endoscopy in the early diagnosis and management of complicated GI trichobezoars.
