Two surgical cases of intestinal obstruction in children due to trichophagia, a form of pica are reported with a reference to the literature. Patient I, a 2.5-year-old girl was admitted to the hospital with a chief complaint of vomiting. An upper gastrointestinal series showed duodenal dilatation with complete obstruction in the 3rd portion of the duodenum. Exploratory laparotomy revealed a soft mass in the dilated duodenum with a windsock web. This was composed of cotton or wool threads and strings. Patient II, a 5-year-old girl presented with abdominal pain and vomiting. Upright films of the abdomen showed multiple loops of small bowel with air fluid levels. She went to surgery for removal of a trichobezoar 6.0×3.0cm in the small intestine 150cm proxymal to the end of ileum. Iron deficiency anemia was not seen in either patient, and they were refered to the outpatient psychiatry clinic, and they no longer have hair pulling and trichophagia.
