Endoscopic shaving of hair in a gastric bypass patient with a large bezoar

Trichotillomania can be associated with the formation of trichobezoars (hair ball) usually located in the stomach. Trichobezoars may lead to complications including bowel obstruction, and perforation. Patients with a history of diabetes, certain psychiatric disorders, prior gastric surgery and poor mastication ability are at an increased risk of developing bezoars. We are presenting a case of patient who suffered from a large, recurrent trichobezoar, who had a history of gastric bypass surgery as well as trichotillophagia. The endoscopic method used to remove the large bezoar will also be discussed. We have reviewed the cases published, in which patients developed bezoars after undergoing gastric bypass surgery. The purpose of this study is to raise awareness among clinicians that patients with certain psychiatric issues who had prior gastric surgeries, are at eminent risk of bezoar formation. A multidisciplinary approach including cognitive behavioural therapy, dietary education and pharmacotherapy should be taken to prevent complications.
