Abstract

A 9-year-old girl presented with a chief complaint of abdominal pain. Esophagogastroduodenal endoscopy (EGD) identified a long and large gastric trichobezoar extending into the duodenum. We attempted endoscopic retrieval after informed consent was obtained from the patient’s mother. Initially, a gasper with 5-prolongs, commonly used for retrieval of endoscopically excised polyps, failed to remove the whole trichobezoar. When a net was used instead, it proved impossible to remove the trichobezoar completely. Therefore, we withdrew the scope from the mouth, leaving the net grasping the tricobezoar firmly in the stomach. Subsequently, we were able to retrieve about 70% of the trichobezoar manually by grasping the snare part of the net directly. A second pass found no deep laceration or perforation endoscopically. The remaining trichobezoar was completely retrieved with the net. The procedure was completed within 15 min. The retrieved specimens were 34 cm in length and 100 g in weight. The patient was discharged uneventfully 5 d thereafter. She was advised to visit a psychiatrist to avoid suffering from a relapse. Follow-up EGD showed no trichobezoar, and the patient’s frontal hair grew back.
