Abstract

We report a case of duodenal obstruction due to gastric trichobezoar. An 11-year-old girl admitted for abdominal pain and vomiting, was found to have a firm mass palpated in the left upper abdomen. Blood studies showed elevated white blood cell counts, ALT, γ-GTP, and amylase. Computed tomography (CT) showed a large intraluminal gastric mass containing air and a mass with the same pattern in the duodenum. The girl had developed a habit of eating her hair as a 7-year-old, leading to a diagnosis of duodenal obstruction due to the trichobezoars. We removed the trichobezoars from the stomach and duodenum in emergency laparotomy. Gastric trichobezoar extended the trichobezoar to the duodenum, it was causing duodenal obstruction and elevated ALT, γ-GTP, and amylase. Diagnosis thus requires questions to patients about a history of trichophagia, in addition to suggestive CT findings.
