Colonic Trichobezoar Causing Acute Large Bowel Obstruction.

ABSTRACT

A trichobezoar is a solid mass of undigested hair that accumulates in the gastrointestinal tract that is typically associated with trichotillomania and trichophagia. Most documented cases are reported to be found in the stomach and small intestine. We report a case of a complete large bowel and small bowel obstruction secondary to a trichobezoar in an 81-year-old male with abdominal pain for one month. He presented to the emergency department with sudden onset nausea, vomiting, constipation, and severe abdominal pain, prompting him to come to the emergency department. CT demonstrated a mechanical obstruction with a transition point at the splenic flexure with pneumatosis. He was taken for urgent exploratory laparotomy, where a colotomy was made and the obstructive intraluminal mass in the transverse colon was identified and removed, and a transverse colostomy was matured. Subsequent pathology revealed the mass as hair and fecal material, confirming a diagnosis of colonic obstruction due to trichobezoar.
